摘要
以二甲基亚砜-四乙基氯化铵混合物为溶剂,乙醇为固化剂,在玻璃板上铸膜制成纤维素/聚烯醇共混物薄膜。借助FTIR-ATR研究了该薄膜的表面性质。结果表明,在薄膜玻璃面一侧,聚乙烯醇浓度高于纤维素,而在乙醇而一侧则无组分浓度的差异。
The surface character of cellulose/polyvinyl alcohol (CELL/PVA) blend films prepared by casting on a glass plate from a solvent of dimcthyl sulfoxide and tetraethyl ammonium chloride and then coagulating with ethanol was studied in terms of fourier transform infrared spectroscopy-attenuated total reflection spectroscopy (FTIR-ATR). The results showed that the PVA is richer than CELL at the glass-side surface of the blend films, whereas, on selectivity is detected at the ethanol-side surface.
