制备了新型硬质聚氯乙烯/超细全硫化粉末橡胶（UFPR）/未处理纳米碳酸钙（UNCC）三元纳米复合材料。TEM观察表明，UFPR（约150 nm）的加入使UNCC粒子（约40 nm）在PVC基体中达到了良好的分散。有趣的是，由于UNCC和NBR-UFPR的协同效应，PVC三元纳米复合材料在耐热性和韧性方面优于相应的PVC二元纳米复合材料以及纯硬质PVC。
Novel rigid poly(vinyl chloride)/ultrafine full-vulcanized powdered rubber (UFPR)/untreated nano-sized calcium carbonate (UNCC) ternary nanocomposites were fabricated. TEM observation revealed that good dispersion of UNCC particles (about 40 nm) in the PVC matrix was achieved with the help of UFPR (about 150 nm). Interestingly, the PVC ternary nanocomposites excel corresponding PVC binary ones, as well as neat rigid PVC, in both heat resistance and toughness due to the synergistic effect of UNCC and NBR-UFPR.
