Abstract

The basic factors influencing the quality of thin films prepared by the spin-coating technique from thermosetting stoichiometric epoxy-amine mixtures have been studied. It has been shown that films 2.5–3.0 nm thick are formed on silicon supports from a 0.025 wt % solution of the stoichiometric mixture of epoxy resin and amine in toluene. Multilayer polymer coatings with thickness up to 40 nm have been prepared from successively deposited partially cured epoxy-amine layers. The thickness of these coatings grows linearly with an increase in the number of layers, while their surface energy decreases. The revealed features may be used for creating multilayer polymer coatings, the properties of which vary along the coating thickness.

热固性环氧胺体系旋涂法制备多层超薄涂料的特点

摘要

研究了影响旋涂技术从热固性化学计量环氧胺混合物制备的薄膜质量的基本因素。已经表明，由0.025 wt％的环氧树脂和胺的化学计量混合物在甲苯中形成的溶液在硅载体上形成2.5–3.0 nm厚的膜。由相继沉积的部分固化的环氧胺层制备了厚度高达40 nm的多层聚合物涂层。这些涂层的厚度随着层数的增加而线性增长，而它们的表面能却下降。所揭示的特征可用于产生多层聚合物涂层，其性质沿涂层厚度变化。
