Abstract

Infrared reflection-absorption spectra (IRRAS) at the near-normal incidence of polystyrene films from benzene, toluene, and chloroform solutions were analyzed in this paper. The appearance of the spectrum can be affected so that false conclusions can be drawn about the positions and the shape of the absorption bands. The knowledge of these influences of residual solvents in the polymer film is important for the correct interpretation of the reflection-absorption spectra. Unlike other approaches, a single reflection at a 20° incidence angle was used. A new drop-carting technique was used for the deposition of polymer film solutions on metal mirrors. Reflection-absorption spectra at a near-normal incidence angle were obtained using a dispersive infrared spectrometer.

溶剂对金属反射镜上聚苯乙烯薄膜吸收带形貌的影响

本文分析了聚苯乙烯薄膜在苯、甲苯和氯仿溶液中的近正入射红外反射吸收光谱。光谱的外观可能会受到影响，因此可以得出关于吸收带的位置和形状的错误结论。了解聚合物薄膜中残留溶剂的这些影响对于正确解释反射吸收光谱是很重要的。与其他方法不同的是，该方法采用了20°入射角的单反射。提出了一种新型滴镀技术，用于在金属反射镜上沉积聚合物膜溶液。利用色散红外光谱仪获得了近法向入射角下的反射吸收光谱。
