In this study, a series of reversible thermochromic microencapsulated phase change materials (TC-MPCMs), exhibiting excellent latent heat storage-release performance, were designed and fabricated successfully. The characterization and microstructure regulation of TC-MPCMs were conducted systematically as well. The core of TC-MPCMs was comprised of crystal violet lactone employed as thermochromic colorant, bisphenol A employed as developer and 1-tetradecanol employed as co-solvent, respectively. These influencing factors of encapsulation process such as the amount of emulsifier, stirring rate, feeding weight of core/shell ratio, acid resistance and thermal cyclic durability were carried out to clarify the effect of various experimental conditions. The surface morphology, shell thickness and core?shell structure of TC-MPCMs were characterized via optical microscope (OM), thermal field emission scanning electronic microscope (TFE-SEM), transmission electron microscope (TEM), respectively. From different scanning calorimetry (DSC) analysis, the performance of temperature of fusion and crystallization and enthalpy of TC-MPCMs under various conditions were measured as well. The results of thermogravimetric (TG) analysis illustrated the influence on thermal stability of TC-MPCMs. In addition, Lab color space obtained by colorimeter is certainly intuitive to observe the colorimetric characteristics of TC-MPCMs as well. More importantly, the reversible thermochromic property associated with phase state of the 1-tetradecanol could also provide a visual evidence of energy storage or release performance of the TC-MPCMs. Furthermore, The TC-MPCMs exhibited excellent stability even after 100th thermal cycling test without any obvious performance degradation, including the morphology, phase change properties and thermal stability. In the end, the fire fighter protective clothing containing TC-MPCMs was designed and fabricated, which could provide adequate thermal protection in the various fire environments. Thus, TC-MPCMs developed in this work showed great potential applications in thermal protective clothing and other thermal regulation fields.

A current concern with in vitro mammalian cell genotoxicity testing is the high frequency of false or misleading positive results caused in part by the past use of excessively high test concentrations. A dataset of 249 industrial chemicals used in Japan and tested for genotoxicity was analyzed. Of these, 116 (46.6%) were positive in the in vitro chromosomal aberration (CA) test, including 6 that were positive only at test concentrations >10. mM. There were 59 CA-positive chemicals at test concentrations ?1. mM. At >1. mM, 51 chemicals were CA-positive, including 13 Ames-positive chemicals, which were therefore not “missed” by the test battery. Thus, 38 potentially positive chemicals would not have been detected in the test battery if the top test concentration was limited to 1. mM in CA test. Analysis of the relevance of CA results on the 38 missed chemicals was conducted based on a weight of evidence approach, including evaluations of effects of extreme culture conditions (low pH, high toxicity, or precipitation), in silico structural alert analysis, in vivo genotoxicity and carcinogenicity test data (where available), mode of action, or information from closely related chemicals. After an exhaustive review, there were four chemicals with some concern for human health risk assessment, nine with minimal concern, and the remaining 25 with negligible concern. We apply different top concentrations to the 38 missed chemicals to identify the most accurate approach for predicting the genotoxicity of industrial chemicals. Of these 2. mM or 1. mg/mL, whichever is higher, was the most effective in detecting these chemicals, i.e., relatively higher (8/13) or lower (17/25) detection among 13 chemicals with some or minimal concern, or 25 with negligible concern, respectively. Lower top concentration limits, 1. mM or 0.5. mg/mL, whichever is higher, are not as effective (2/13) for detecting these chemicals with concern. Therefore, we conclude 2. mM or 1. mg/mL, whichever is higher, would be an appropriate top concentration limit for testing industrial chemicals for chromosome damage.

Media formulated using two compounds (a leuco dye and 4-alkoxyl-4?-hydroxybiphenyl) were colored in the amorphous state and colorless in the crystalline state. As the alkyl chain length of the biphenyl compound increased, the contrast ratio and thermal stability of the amorphous states increased. Additionally, the crystallization velocity increased for the media with a long alkyl chain. Leuco dyes with a high glass transition temperature also produced thermally stable amorphous states. The origin of the long alkyl chain effects is discussed.

Several binary composites based on Crystal Violet Lactone (CVL) color former and Phenolphthalein (PPht) developing agent dissolved in 1-tetradecanol (TD) were studied in order to determine how different ratios between components influence the thermochromic behavior of the composites. The color dependence on temperature was investigated in direct relationship with structural changes and interactions between components. The stoichiometry of the colored complex was determined from diffuse reflectance data and confirmed by means of steady state fluorescence measurements and temperature modulated differential scanning calorimetry. The color former: developing agent molar ratio equal to 1:2.5 was determined to ensure the reversibility of the process in optimal conditions. The characteristics of the color path and the influence of thermal history during thermochromic transition were analyzed from the variations of CIELAB color parameters during successive heating/cooling cycles. Dynamic colorimetric properties of the thermochromic binary composite containing the components in optimum ratio are described by four characteristic temperatures in the hysteresis.

Construction materials play a crucial role in the thermal behaviour of the urban space as well as the building energy consumption and indoor environmental quality. Recently, there has been growing interest in optical construction materials/coatings as an effective method to minimise energy use, improve indoor and outdoor thermal comfort and fight urban overheating. Thermochromic materials as one of the advanced optical materials that change their optical properties/colour as a function of the ambient temperature can present lower/higher surface temperature than conventional materials during the warm/cold periods. Although pilot applications of thermochromic materials in the built environment shown a tremendous energy conservation potential, the serious optical degradation they exhibited, restricts seriously their use. Recent development in the field of thermochromic materials including quantum dots, plasmonics, photonic crystals, conjugated polymers, Schiff bases, liquid crystals, and nano optical filters for Leuco dyes present fascinating and impressive characteristics, enhance significantly the potential of thermochromic materials and opens new opportunities for the development and use of advanced cutting-edge optical materials. The present paper aims to offer a comprehensive overview of the recent developments on advanced thermochromic materials and on their energy conservation potential.

In the present study, eight self-thermochromic fluorans (STC1-STC8) were synthesized, and their reversible thermochromic properties were investigated without the use of a color developer. This work demonstrated the role of the phenol group on ring c on the thermochromic reversibility of the fluorans. Furthermore, the two-component mixtures that contained fluorans and methyl stearate were used to examine the thermochromic behaviors of the fluorans with steady heating and cooling rates. The thermochromic properties of the fluorans were evaluated using solid-state UV-Vis, reflectance and FT-IR spectroscopic techniques. DFT calculations were conducted to justify the optical behaviors of the fluorans in their spirolactam forms (STC1-STC8) and cationic forms (STC1+- STC8+). Finally, STC1 was successfully microencapsulated and applied in acrylic fiber to use as thermal indicators.
