Abstract
The present work represents an important attempt at constructing a phase diagram for predicting the type and extent of fibrillation of the liquid crystalline polymer (LCP) phase in LCP-based polymer blends. A polycarbonate (PC)/LCP polymer blend was utilized in the current study. The combined effects of three factors, namely, the shear rate, the LCP content in the blend, and interfacial adhesion between the LCP phase and the matrix polymer (PC) were considered. In contrast, work in reported literature has usually considered the individual effect of only one or at most two of these three factors. A thermotropic liquid crystalline polymer, LC5000, consisting of 80/20 of hydroxybenzoic acid and poly(terephthalate) was employed. The effect of interfacial adhesion between the LCP and the PC matrix on fibrillation was considered by using a compatibilizer for the PC/LCP blend. It was demonstrated that the constructed phase diagram could successfully be used to predict and illustrate the conditions under which in situ fibrillation of the LCP phase would occur in the LCP-based blend.
