利用有机硅偶联剂改性的纳米炭黑和聚氨酯制备了纳米炭黑/聚氨酯复合物.采用红外光谱、透射电镜、流变学及力学性能等测试方法对纳米粒子及其聚氨酯复合物进行了表征.红外光谱表明,纳米粒子的存在使聚氨酯的氢键结构发生了改变.适量改性纳米炭黑粒子明显提高了聚氨酯的拉伸强度和断裂伸长率等力学性能.流变学测试结果表明,溶液中改性纳米炭黑粒子与聚氨酯分子间存在明显的相互作用. ; Surface modified nano carbon black particles(MCB) were used to prepare PU/MCB and PU/CB composites. FTIR, TEM, rheological methods and mechanical properties test were utilized to characterize the nano particles and their composites. FTIR results indicate that partial hydrogen-bonding structure in PU composites changed due to the interaction between nano particles and PU molecules. The tensile strength and elongation at break of the PU/MCB composites can be reinforced by adding optimal content (<5%) of MCB particles. The rheological results indicate that there are obvious interactions between PU molecules and carbon black particles in solution. ; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000260453500039&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E) ; 中文核心期刊要目总览(PKU) ; 中国科技核心期刊(ISTIC) ; 中国科学引文数据库(CSCD) ; 7 ; 10 ; 2096-2100 ; 29
