摘要
以表面具有螫合官能团的高分子材料Poly（BA-co-GMA-IDA）为高分子液体模板，制备了Y2O3功能性溶胶复合薄膜。测试结果显示，Y2O3功能性混和溶胶薄膜具有优异的抗近红外／紫外性能，其薄膜对320nm以下的中短紫外光阻隔率〉97％（300nm以后可完全隔绝紫外），对320-380nm的长波紫外线的阻隔率也〉60％；近红外阻隔率可以达到70％以上。以高分子模板制备复合薄膜的抗近红外／紫外性能明显优于未用高分子模板制备的同类型薄膜。
For ameliorating aggregation of nano particles in organic/inorganic composite film, a novel Y2O3-containing sol-gel composite film was synthesized on chelating polymer template-Poly（BA-co-GMA-IDA）. UV-VIS and FTIR experimental results demonstrated the polymer template method was better than the routine preparation. In ultraviolet region, the transmittance remarkably lowered from 350 nm and reached to 0 when the frequency was less than 300nm. Meanwhile, in near infrared wave range the transmittance was 30%.
