Novel nanocomposites of benzofuran-containing polymer poly(2-(5-bromo benzofuran-2-yl)-2-oxoethyl methacrylate) with different contents of organoclay were prepared and characterized with FTIR, XRD and SEM techniques. The thermal decomposition temperature of poly(BOEMA)/organoclay nanocomposites is higher than that of pure poly(BOEMA) about 5-14 °C at 10% weight loss. The optical characterization was tested with a UV-VIS spectrophotometer. Transmittances of nanocomposites decreased to lower values by organoclay loading. Dispersion parameters such as steepness parameter, single-oscillator parameter, average oscillator position and strength and moments of the imaginary part of the optical spectrum were changed as a function of organoclay nanofiller. As the organoclay content increased to 5% in the polymer matrix, the existence of wide-band tails increased to 1.30 eV, whereas the optical energy gap decreased to 2.92 eV. Anal. reveals that the type of transition is the indirectly allowed one. In the experiment, the researchers used many compounds, for example, 1-(5-Bromobenzofuran-2-yl)ethanone (cas: 38220-75-6Related Products of 38220-75-6).
1-(5-Bromobenzofuran-2-yl)ethanone (cas: 38220-75-6) belongs to benzofurans derivatives. Benzofuran is the “”parent”” of many related compounds with more complex structures. For example, psoralen is a benzofuran derivative that occurs in several plants. They are also prone to polymerisation in the presence of concentrated mineral acids and Lewis acids.Related Products of 38220-75-6
