研究了聚乙烯醇（ＰＶＡ）／聚丙烯酰胺（ＰＡＡｍ）共混体系在聚乙烯、涤纶和玻璃３种不同的基板界面场中所形成的高分子膜在相形态上的差异．通过差示扫描量热法（ＤＳＣ）、红外光谱以及显微镜对ＰＶＡ／ＰＡＡｍ体系在３种基板界面的作用下制备的样品作断面观察和测试，并进行粘附功的估算，结果表明，在玻璃基板上成膜可以发生有规相分离；这说明可以通过对聚合物和基板界面的控制，制备中间含梯度结构的复合膜
The differences in phase morphology of polymer films formed in the interface between PVA / PAAm blends at three different substrate interfaces of polyethylene, polyester and glass were studied. The samples prepared under the action of three substrate interfaces of PVA / PAAm system were observed and tested by differential scanning calorimetry (DSC), infrared spectroscopy and microscopy. The adhesion work was evaluated. The results showed that in the glass The film can be formed on the substrate with a regular phase separation; This shows that the interface between the polymer and the substrate can be controlled to prepare the intermediate gradient structure of the composite film
