采用溴化聚（异丁烯-对甲基苯乙烯）（BIMS）橡胶和十八胺改性的蒙脱土纳米粘土制备了聚合物基纳米复合材料。使用X射线衍射技术（XRD），傅里叶变换红外光谱（FTIR），和机械性能的性质和加载的炭黑对这些纳米复合材料和控制BIMS的效果进行了彻底的研究。将4份改性纳米粘土添加到20 phr N550炭黑填充的样品中，拉伸强度增加了53%。在三种不同等级的炭黑（N330、N550和N660）中，N550显示出最好的纳米粘土效果。在20 phr填料用量下获得了最佳结果。为了比较，使用相同负载的瓷土和二氧化硅。分别将4份纳米粘土添加到二氧化硅和瓷土填充样品中，实现了拉伸强度的五十六和46%的改善。N330炭黑（20份）填充的基于丁苯橡胶（SBR）的纳米复合材料在4份改性纳米粘土的情况下记录了高20%的拉伸强度。在所有上述炭黑填充的纳米复合材料中，模量在30至125%的范围内提高。© 2005威利期刊有限公司应用聚合物科学杂志96：443-451，2005
Polymer based nanocomposites were prepared using brominated poly(isobutylene-co-paramethylstyrene) (BIMS) rubber and octadecyl amine modified montmorillonite nanoclay. The effect of nature and loading of carbon black on these nanocomposites and the control BIMS was investigated thoroughly using X-ray diffraction technique (XRD), Fourier transform infrared spectroscopy (FTIR), and mechanical properties. The addition of 4 parts of the modified nanoclay to 20 phr N550 carbon black filled samples increased the tensile strength by 53%. Out of the three different grades of carbon black (N330, N550, and N660), N550 showed the best effect of nanoclay. Optimum results were obtained with the 20 phr filler loading. For comparison, china clay and silica at the same loading were used. Fifty-six and 46% improvements in tensile strength were achieved with 4 parts of nanoclay added to the silica and the china clay filled samples, respectively. N330 carbon black (20 parts) filled styrene butadiene rubber (SBR) based nanocomposite registered 20% higher tensile strength with 4 parts of the modified nanoclay. In all the above carbon black filled nanocomposites, the modulus was improved in the range of 30 to 125%. © 2005 Wiley Periodicals, Inc. J Appl Polym Sci 96: 443–451, 2005
