采用接触角/界面张力测定仪、电子顺磁共振波谱(ESR)、X射线衍射仪(XRD)、傅里叶变换红外光谱仪(FT-IR)分析了炭化、微波处理后竹束的物理化学性能,利用经过不同预处理的竹束制备了竹木重组材,研究了预处理对竹木重组材物理力学性能的影响。结果表明,炭化处理后竹束表面接触角变大,微波处理后竹束表面接触角变小;炭化处理后竹束表面的自由基浓度降低,微波处理后的竹束表面自由基浓度增大;炭化、微波处理均能使竹束表面纤维素结晶度增大,但炭化处理结晶度增幅较大;炭化处理后竹束表面亲水性羟基减少,而微波处理后竹束亲水性羟基增加;预处理竹木重组材的MOR值较未处理材降低,MOE值变化幅度很小,炭...

The physical and chemical property of bamboo strip treated by carbonization and microwave was researched by the analysis methods of contact angle/interfacial tension meter, ESR, XRD and FT-IR. The physical and mechanical properties of bamboo-wood hybrid scrimber prepared by pretreated bamboo strips was researched. The research results showed that the contact angle of bamboo strip surface treated by carbonization was higher than that with no pretreatment, while the contact angle of bamboo strip surface treated by microwave was lower than that with no pretreatment. The free radicals concentratio...
