Synthesis and Properties of CNTs/Natural Rubber Composite

摘要

In this study,the carbon nanotubes (CNTs) were dispersed into natural rubber solution in different contents of 0,1,3,5,10 and 20 wt%.The CNTsatural rubber composites were subsequently attained by evaporating the solvent and vulcanizing the sheet.In order to evaluate the interaction between natural rubber and CNTs,the nanocomposites were studied using SEM and Raman spectroscopy techniques respectively.The G band and G′band of CNTs were observed after conducting CNTs into natural rubber polymer.Additionally,uniaxis tensile test and dynamic mechanical analysis (DMA) measurement were performed.The initial modulus of CNTsatural rubber composites increased with a slope of about 0.43%Mpa/wt% in accordance with the result from DMA.
