分别采用紫外辐照和硅烷偶联剂(KH550)对聚酯(PET) /SiO_x膜的SiO_x镀层进行表面改性以制备PET/SiO_x /壳聚糖-纳米ZnO复合膜。水接触角测试发现,相比于紫外辐照,KH550改性能显著改善SiO_x的表面亲水性,从而成功制备得到PET/SiO_x /壳聚糖和PET/SiO_x /壳聚糖-纳米ZnO复合膜。随后采用电子扫描显微镜(SEM)观测复合膜的微观形态,并对该膜的力学性能、阻隔性和抑菌性进行了表征。SEM照片显示,该复合膜表面光滑,断面呈现层状结构。对该膜的力学性能测试结果发现,表面镀层(SiO_x)使PET膜的力学性能有所改善,但涂层(KH550、壳聚糖和壳聚糖-纳米ZnO)对PET/SiO_x膜的力学性能无显著影响。SiO_x镀层能有...

The chitosan and/or ZnO(nano-particle)-doped chitosan layers were synthesized by spray coating on the substrate of PET/SiO x membrane surface-modified with KH550 transition layer or by ultraviolet (UV) irradiation.The impact of the KH550 layer or UV-irradiation on the interface adhesion and properties of PET/SiO x membrane was investigated with scanning electron microscopy and conventional surface probes.The preliminary results show that the ZnO-doped chitosan and KH550 composite layers improved,to varying degrees,the interfacial adhesion,perme...
