摘要

为改善木材的疏水性能,先采用二氧化钛（TiO2）溶胶进行处理,再分别用低表面能物质硬脂酸、十六烷基三甲氧基硅烷（HDTMS）进行改性处理。结果表明,改性试样表面负载有纳米级TiO2颗粒,表面修饰了低表面能物质;改性试样的水接触角较未处理材大幅提高;HDTMS比硬脂酸显示出更优良的疏水性能。

Abstract

In order to improve the hydrophobic characteristics of wood,wood surface was modified by a TiO2 solution followed by a low surface energy treatment with stearic acid and hexadecyltrimethoxysilane（HDTMS）,respectively.The results showed that the wood surface coated with TiO2nanoparticles and the hydrophobic agents were introduced successfully onto the surface of the nanoparticles.Compared with the wood coated with TiO2only,the water contact angles of the modified wood showed remarkable improvement and the HDTMS resulted in superior hydrophobic improvement over stearic acid.
