摘要: Abstract In this study, the poly(methyl methacrylate) (PMMA)/carbon fibers (CFs) composite films with different CFs concentrations have been prepared using solution casting technique. were modified aqua regia to reduce aggregations. The residual aspect ratios (ARs) of in are 49, 105, 227, 312, 417, 527 and 616, respectively. Light microscopy SEM applied investigate morphology films. resistance film ARs was measured (1) perpendicularly (2) along in-plane direction. Both percolation thresholds ϕc,⊥ ϕc,∥ determined by fitting Mclachlan GEM equation. conductivity both directions presented contour plot versus concentration CFs. A huge amount experimental data obtained seven ratio (AR) multiply 12 volume fraction two measuring directions. Based on Balberg's excluded volume theory, for first time pre-factors K⊥ K∥ revealed, considering direction film.
