摘要
通过接触角测定仪、X射线光电子能谱仪(XPS)、红外光谱仪(FTIR)探讨毛竹经漂白和热处理后的表面自由能、表面元素和化学成分变化,并与未处理材料进行对比。结果表明:漂白和热处理后的竹材表面润湿性能提高,碳原子的氧化程度和表面羰基数目增加;漂白竹材的表面润湿性能低于热处理竹材,表面氧化程度和羰基增加数量略高于热处理竹材。
Surface wettability,elemental change and chemical components＇ change of untreated bamboo,bleached bamboo and heat treated bamboo were measured by contact angle meter,X-ray photoelectron spectrometer（XPS）and fourier transform infrared spectroscopy（FTIR）,respectively.Results showed that surface wettability,oxidized form of C atom and carbonyl number on the surface of treated bamboos were improved.Bleached bamboo was low in surface wettability,but high in oxidized degree of C atom and carbonyl number,compared to those of heat treated bamboo.
