Abstract

In this paper, we reported the synthesis of TiO₂/γ-(methacryloyloxy)propyltrimethoxysilane (KH570) hybrid nanoparticles with simple and mild condition at room temperature. The as-prepared TiO₂/KH570 hybrid nanoparticles were characterized by FT-IR, XRD, SEM, EDS, and XPS. The hybrid nanoparticles were coated onto the surfaces of polyethylene terephthalate (PET) fabrics by pad-dry-cure (PDC) process. The morphology, structural, and chemical composition of the coated fabrics were analyzed by SEM, EDS, and XPS. The ultraviolet protection factor (UPF) was used to evaluate the UV protection property of PET fabrics. The coated PET fabric exhibited good UV resistance abilities with a UPF value of 50+. The air permeability of the coated PET fabrics decreased significantly compared with the original PET fabrics. The coated PET fabrics also showed good washing stability. The coated fabrics had an excellent protective effect against ultraviolet rays after exposure to ultraviolet light for a period of time. The PDC process only caused a small degree loss of the tensile strength of the coated PET fabrics.

无机-有机杂化纳米粒子及其在PET织物防紫外线中的应用

摘要

本文报道了简单，温和的室温条件下TiO ₂ /γ-（甲基丙烯酰氧基）丙基三甲氧基硅烷（KH570）杂化纳米粒子的合成。制备的TiO ₂/ KH570杂化纳米颗粒通过FT-IR，XRD，SEM，EDS和XPS表征。通过垫干固化（PDC）工艺将杂化纳米颗粒涂覆到聚对苯二甲酸乙二醇酯（PET）织物的表面上。通过SEM，EDS和XPS分析涂覆织物的形态，结构和化学组成。紫外线保护因子（UPF）用于评估PET织物的紫外线保护性能。涂覆的PET织物具有良好的抗紫外线能力，UPF值为50+。与原始的PET织物相比，涂覆的PET织物的透气性显着降低。涂覆的PET织物还显示出良好的洗涤稳定性。涂覆的织物在暴露于紫外线一段时间后具有优异的抗紫外线保护作用。
