以聚丙烯无纺布为基材，表面紫外光诱导接枝丙烯酸，又依次通过酰胺化、酰肼化、叠氮化，以及紫外光辐照偶联明胶，得到吸附单宁性能较好的改性材料.通过质量法、傅里叶变换红外光谱、热重/差热及扫描电镜等对基材、中间产物及最终产物进行了官能团测定、结构表征和吸水性能测定，结果表明各步反应均按预期引入了目标官能团，所制备的改性材料对单宁的最大吸附量为84．30 mg/g.

Polypropylene non-woven fabric was used as substrate,acrylic acid was grafted onto the PP films via UV irradiation,followed by amidate,hydrazide,azidation and coupling gelatin molecules via UV irradiation. The material with good adsorption performance for tannin acid was obtained.Weighing method,Fourier trans-form infrared spectroscopy,thermogravimentry-differential thermogravimetry and scanning electron microscopy were used to measure functional groups,characterize structures and hygroscopic property of the substrate,in-termediate and final products.The results show that all the reactions introduced target groups according to the prospection,the maximum adsroption of modified material for tannin acid was 84.30 mg/g.
