摘要
Abstract
Dispersibility of cellulose nanocrystal (CNC) in water before and after adding a dodecyl trimethyl ammonium chloride (DTAC) surfactant was investigated,and then polylactic acid (PLA)/CNC composites were prepared by a solution casting method.The results indicated that the aggregation of CNC was effectively reduced with the aid of DTAC,and the compatibility between PLA and surface-treated CNC was improved due to the formation of hydrogen bonding.Moreover,the heterogeneous nucleation of PLA could be promoted in the presence of surface-treated CNC,leading to an increase in crystallinity of PLA matrix.The tensile strength of composites was improved by 70.7 ％ with the addition of 2 wt ％ surface-treated CNC,but their elongation at break decreased.关键词
