Polystyrene-alumina hybrid free standing films with amino-functionalized breath figure (BF) cavities were fabricated from a suspension of the amino-functionalized amphiphilic-modified alumina particles in polystyrene/chloroform solution by employing a one-step casting process. The role of the film thickness and the particle concentration on the BF microstructural aspects such as the pore size, pore d., amino group surface d., etc. was reported. The dry film thickness increased from 0.91 to 5.6 μm on increasing the wet film thickness from 0.2 to 1 mm. The pore size increased with the film thickness, while the pore d. and the porosity decreased. Relatively uniform pore size was observed for an ∼3 μm thick film in which the moderately ordered BF pattern was more or less maintained up to a particle concentration of 5 wt % of the polystyrene content. While the 0.91 μm thick film exhibited through-pore structure, concavities were formed in thicker films. The particle-assisted BF formation favored the formation of amino-functionalized cavities. The surface d. of the amino functionality reduced on increasing the film thickness, whereas the d. increased with the particle concentration The implications were discussed. In the experiment, the researchers used many compounds, for example, 4-Phenyl-3H,3’H-spiro[furan-2,1′-isobenzofuran]-3,3′-dione (cas: 38183-12-9Recommanded Product: 38183-12-9).
4-Phenyl-3H,3’H-spiro[furan-2,1′-isobenzofuran]-3,3′-dione (cas: 38183-12-9) belongs to benzofurans derivatives. Benzofurans are compounds with a planar structure having 10 pi electrons that include the lone pair on oxygen atom, which makes it more susceptible to electrophilic attack. Substituted benzofurans find applications such as fluorescent sensors, oxidants, in drug discovery, and in another field of chemistry and agriculture.Recommanded Product: 38183-12-9
