摘要

In this work, poly(para-phenylene terephthalamide) (PPTA)-pulp was investigated in view of employment in functional paper-based materials as reinforcement, bonding, and filling materials. The morphological characteristics, fibrillation degree and the role of PPTA-pulp, the ratio of PPTA-pulp to PPTA fiber on the mechanical properties, and paper formation uniformity of the functional base paper were discussed. The results showed that the ductile, rough, and highly fibrillating morphological characteristics of PPTA-pulp are helpful to give rise to some distinctive properties such as wet-machinability and reinforcement effects in composite materials. Fibrillation of PPTA-pulp significantly contributes to generating more highly dispersed slender threadlike micro-fibrils and improving the properties of base paper. This research suggested a significant reinforcement, bonding, and filling potential of PPTA-pulp for the production of functional paper composite materials. (c) 2015 Wiley Periodicals, Inc.
