主　　题：Microfiber properties bamboo steam explosion Chimonobambusa quadrangularis Qiongzhuea tumidinoda 

摘      要：To overcome the shortage of wood resources as well as to develop novel natural fibers materials,the Chimonobambusa quadrangularis(CQ)and Qiongzhuea tumidinoda(QT)planted in Southwest China were effectively isolated by the steam explosion(SE).The fine and uniform bamboo microfibers derived from CQ and QT were obtained,and their smallest average widths were 12.62μm and 16.05μm,*** effects of steam explosion on the micro-morphology,chemical composition,thermal stability,crystallinity,surface wettability,and mechanical properties of bamboo microfibers were comprehensively *** results showed that the relative content of cellulose in bamboo microfibers increased but the hemicellulose and lignin contents decreased after *** degrees of crystallinity for CQ and QT increased from 40.49%and 39.46%to 68.90%and 55.78%,*** thermal stability and surface hydrophilicity were also *** CQ microfibers had a maximum decomposition temperature of 2.79°C,a tensile strength of 58.54 MPa,an elongation at break of 0.6%,and a water contact angle of 2.7°higher than those of the QT microfibers.
