摘要A better understanding of filler's surface properties is critical for determining the most effective polymer reinforcement fillers. In this work, a colored talc filler (CTF) was prepared and its surface properties were comparatively studied to those of talc filler (TF), using inverse gas chromatography (IGC) and contact angle methods-Owens-Wendt-Kaelble (OWK), van Oss-Chaudhury-Good (vOCG) and Wu. The results indicated that the dispersive component (gamma(D)(S)) for both samples contributed a major part (68-81%) of the total surface energy (gamma(T)(S)), and displayed a decreasing trend with increasing surface coverage, meaning the fairly energetic surface heterogeneity for them. The gamma(D)(S) values determined by the contact angle methods were consistent, although lower than those using IGC analysis. The specific component (gamma(SP)(S)) calculated by the contact angle methods were also consistent and lower than those calculated using IGC. The specific Gibbs free energies of adsorption (Delta G(sp)) changed with surface coverages, further confirming the heterogeneous nature of both samples. The significantly lower gamma(T)(S) value for CTF could reduce filler particle-particle interactions, allowing a better dispersion in matrix, and thus lead to an improvement in mechanical performance of CTF/polymer composite.
