Abstract：The effects of micro-pore parameters, pore size, pore distribution of polyimide matrix micro-porous materials was studied when correlated additives are added in it. 5% (mass fraction) MoS2, 5% Pb and 5% PTFE were added in polyimide powders of grain of 20μm separately at the pressure of 35-105MPa to mold beforehand by molding-pressure process, micro-porous materials were prepared by hot pressing and consolidation in vulcanizer. Pore parameters was measured through foam-diameter instrument. The results show that all pore parameters have changes when 5% MoS2, Pb, PTFE are added, and pore size distributions are disperse obviously, especially the disperse of PTFE is more obviously.
