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。

Abstract:

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.

Key words: bleached bamboo, heat treated bamboo, surface energy, XPS, FTIR
