硅烷偶联剂改性氧化石墨烯/土工布耐磨复合材料的制备
Preparation of silane coupling agent-modified graphene oxide/geotextile wear-resistant composites
摘要
Abstract
Silane coupling agent KH550 was used to modify graphene oxide surface functionalization,and then a series of modified graphene oxide/PU membranes were prepared by foaming and coating process us-ing waterborne polyurethane(PU2540)as the substrate,modified graphene oxide as the functional filler,and sodium dodecyl sulfate as the blowing agent,focusing on the mechanism of the effect of the hydrolysis condi-tions of KH550 on the abrasion resistance of the membrane.The experimental results showed that the opti-mized hydrolysis conditions could effectively promote the formation of stable covalent bonding between the oxygen-containing functional groups on the surface of graphene oxide and the hydrolysis products of KH550,which significantly enhanced the interfacial bonding strength between the graphene oxide and the PU matrix.As confirmed by Martindale abrasion test,the abrasion resistance of the modified film was 159.51 times high-er than that of the unmodified film.The membrane with optimal abrasion resistance was further composited with geotextile through bonding process,and the UV protection,aging resistance,corrosion resistance and hy-drophilic and hydrophobic properties of the composites were systematically investigated.Compared with the unmodified composites,KH550 not only greatly improved the wear-resistant performance,but also gave the composites more excellent UV protection performance.The important theoretical guidance and technical sup-ports for the development of high-performance graphene oxide reinforced polymer composites are provided,which has a broad application prospect in the field of functional protective materials.关键词
