用原子力显微镜(AFM)和接触角测量仪对丁内酯改性氨基聚硅氧烷的膜形貌及其排列方式进行研究,并与应用性能进行分析。结果发现,不同氨基聚硅氧烷所形成的膜形貌不同,膜的表面形貌实际上与基团的排列方式有关,氨乙基氨丙基聚硅氧烷在单晶硅基底上形成均匀、平整、光滑的疏水膜;而丁内酯改性的氨乙基氨丙基聚硅氧烷则形成凹凸不平、粗糙的具有一定亲水性的非均匀膜。由于膜形貌存在很大差异,这可能就是造成不同氨基聚硅氧烷性能差异的主要原因。
The morphology and arrangement of butyrolactone-modified aminopolysiloxane were investigated by atomic force microscopy (AFM) and contact angle measurement, and their application performance was analyzed. The results showed that different amino polysiloxane film formed by the different morphology of the membrane surface morphology and group arrangement is actually related to the amino ethylaminopropyl polysiloxane on a single crystal silicon substrate to form a uniform , Smooth, smooth hydrophobic membrane; and butyrolactone modified aminoethylaminopropyl polysiloxane is the formation of uneven, rough with a certain hydrophilic non-uniform film. Due to the large differences in film morphology, this may be the main reason for the differences in performance of the different aminopolysiloxanes.
