Fe3O4/HBPAMAM/ZnO复合材料的制备及其在棉织物上的应用研究

Preparation of Fe3O4/HBPAMAM/ZnO composite materialand its application on cotton fabric

采用溶剂沉淀法制备具有包覆结构的复合材料Fe 3O 4/HBPAMAM/ZnO,并与自制环氧端基超支化聚酰胺HBPAMAM-EP复合整理棉织物,制备具有多功能性和耐洗性能的棉织物。结果表明,复合材料Fe 3O 4/HBPAMAM/ZnO形成良好的包覆结构,表现出较好的光学性能。经Fe 3O 4/HBPAMAM/ZnO与HBPAMAM-EP复合整理的棉织物表面形成有机-无机层并具有一定立体结构;经整理的棉织物紫外线透过率较低,抗紫外线性能优良;光催化性能良好,(紫外灯照射下)3.5 h完全降解亚甲基蓝MB;具有一定电磁屏蔽效果,在部分频段屏蔽效能可达-42 dB;机械性能良好(折皱回复角243°,拉伸断裂强力332 N)。经耐水洗测试表明经整理的棉织物在30次洗涤后,抗紫外线性能、光催化性能以及机械性能(抗皱性能)仍然表现良好。

The composite material Fe3O4/HBPAMAM/ZnO with coating structure was prepared by solvent precipitation method,and the cotton fabric was compounded with the self-made epoxy end-group hyperbranched polyamide HBPAMAM-EP to prepare cotton fabric with versatility and washability.The results show that the composite material Fe3O4/HBPAMAM/ZnO formed a good coating structure and exhibited good optical properties.The organic-inorganic layer was formed on the surface of the cotton fabric composited by Fe3O4/HBPAMAM/ZnO and HBPAMAM-EP and had a certain three-dimensional structure.The finished cotton fabric had low UV transmittance and excellent UV resistance.It showed good photocatalytic performance,completely degrading methylene blue MB in 3.5 h under ultraviolet light irradiation.The shielding effectiveness could reach-42 dB in some frequency bands,showing a certain electromagnetic shielding effect.It had good mechanical properties with wrinkle recovery angle of 243°and tensile breaking strength of 332 N.The washing resistance test showed that after 30 washings,the finished cotton fabric still had good UV resistance,photocatalytic performance and mechanical properties(wrinkle resistance).
