Abstract: PS/PTFE nanocomposites were prepared by a melt blending method, and the effects of PTFE content and morphology on the rheological behaviors and foaming behaviors of PS/PTFE blends were investigated. The results indicated that PTFE could be conducted by in-situ fibrillation to improve the rheological behavior of PS/PTFE blends significantly, thus enhancing the foamability of the blends. Meanwhile, PTFE could act as a highly effective nucleation agent to promote the cell nucleation and reduce cell size and reduced the foam density of the blends accor-dingly.
