摘要
分别采用大分子溶液插层法和大分子熔融插层法制备了苯乙烯-丁二烯-苯乙烯共聚物(SBS)/蒙脱土纳米复合材料,研究了材料的力学性能。纳米结构的形成对复合材料的性能产生显著影响,少量蒙脱土的引入可以明显改善SBS/蒙脱土复合材料的力学性能。无论溶液插层法制备的星型SBS/蒙脱土纳米复合材料,还是熔融插层法制备的线型SBS/蒙脱土纳米复合材料,其拉伸强度和断裂伸长率都同时增加。其中,溶液插层法制备的纳米复合材料的拉伸强度和断裂伸长率分别较纯SBS增加了75%和55%;熔融法制备的纳米复合材料的拉伸强度和断裂伸长率分别较纯SBS增加了70%和18%。
Styrene-butadiene-styrene block copolymer/organic montmorillonite （SBS/MMT） nanocomposites were prepared by solution intercalation and melt intercalation process, respectively. The mechanical properties of the nanocomposites were characterized in detail. The results show that the formation of nano-structure exerts a significant influence on the performance of the composite; the introduction of organic montmorillonite can remarkably improve the mechanical properties of SBS/MMT nanocomposite. Both star-shaped SBS/MMT prepared by solution intercalation and linear SBS/MMT prepared by melt intercalation have an increase in their tensile strength and elongation at break. Compared with pure SBS, the tensile strength and elongation at break of the SBS/MMT prepared by solution intercalation is increased by 75% and 55% respectively, while those values of the SBS/MMT prepared by melt intercalation is increased by 70% and 18% respectively.
