中文摘要：
通过紫外光照射将半频哪醇自由基偶合到双向拉伸聚丙烯（BOPP）膜表面,利用该偶合基团上的羟基与对苯二甲酰氯（TPC）和双酚A（BPA）进行交替反复的逐步缩合反应,制备了以共价键结合的多层组装膜.采用紫外（UV）、红外光谱（ATR-FTIR）跟踪和证实了组装膜的形成,并且膜的组装比较规则.
英文摘要：
A multilayer construction has been fabricated on a bi-oriented polypropylene （BOPP） surface via a chemical bonding assembly process. The first step in the fabrication process involves the introduction of semipinacol groups onto the BOPP surface by hydrogen abstraction by benzophenone （BP） and coupling of the resultant semipinacol radicals with the surface under UV irradiation. The second step involves a condensation reaction between the hydroxyl group of the semipinacol moiety and terephthaloyl chloride （TPC） followed by successive condensation reactions of bis-phenol A （BPA） and TPC. The formation of the assembled film can be conveniently monitored by UV spectroscopy and ATR-FTIR spectroscopy.
