摘　　要：通过原位乳液插层法制备高有机蒙脱土(OMMT)含量的聚丙烯酸丁酯/有机蒙脱土(PBA/OMMT)纳米复合物,将其作为母料与ABS进一步熔融插层制得力学性能良好的ABS/OMMT纳米复合材料,并通过XRD、TGA和TEM等对材料进行了表征。结果表明:制得的PBA/OMMT母料为插层型纳米复合物,OMMT片层间距从2.38nm增大到3.85nm;采用母料法制备ABS/OMMT纳米复合材料,ABS链段易插层进入OMMT层间,使OMMT片层在ABS基体中达到剥离并以纳米尺度均匀分散,较好地保持了ABS的缺口冲击强度。PBA/OMMT nanocomposite with high OMMT mass fraction was prepared by in-situ emulsion intercala- tion polymerization. ABS/OMMT nanocomposite with good mechanical properties was prepared by melt blending ABS with PBA/OMMT masterbatetx XRD, TGA and TEM were used to characterize the nanocomposite. Results showed that the basal spacing of OMMT increased from 2.38nm to 3.85nm in PBA/OMMT, which meaned that intercalated nanocompos- ite was prepared. The OMMT layer was easy to be intercalated by ABS when prepared ABS/0MMT nanocomposite by masterbatching method. It was exfoliated and dispersed in ABS on the level of nanometer dimension, which was proved good in retaining the Izod impact strength of ABS.
