| 摘 要： | 以表面具有螯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.

| Abstract: | For ameliorating aggregation of nano particles in organic/inorganic composite film,a novel Y_2O_3-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%. |
