MELT-PROCESSING OF SBS/POLYANILINE-BASED BLENDS PROCESAMIENTO TÉRMICO DE MEZCLAS A BASE DE SBS Y POLIANILINA
Morphological analysis and electrical conductivity of composites obtained by melt-processing of blends of a polyaniline complex (PANICX) with styrene-butadiene-styrene (SBS) are reported. Blends with PANICX contents ranging from 1 to 50 wt% were first prepared using a two-piece batch mixer, followed by ram-extrusion to obtain cord-like extrudates. The microstructure was analyzed by SEM, and conductivity was evaluated with a Keithley electrometer. The blends’ rheological behavior was also studied. Evidence of formation of well-defined elongated structures was found in most of the extrudates. The extrudates’ conductivity was considerably low. Inhomogeneityrelated problems were observed such as erratic behavior of pressure, “melt-fracture” during the extrusion, and extrudates with irregular microstructure and very low conductivity. This occurred because same size batches were used regardless of blends’ comp
