“…First, CB is distributed predominantly in one phase of the blend. 6,7 Especially, when CB preferentially located in the continuous phase of two polymers, CBfilled phase became conductive after the CB concentration reached the percolation level in that phase, which is referred as ''double-percolation'' effect. 8 Second, the conductive particles mainly locate at the interface of the two-phase polymer blends, 9,10 however no electric properties have been evaluated for these composites with interfacial distribution of CB.…”

The morphology and electrical properties of linear low density polyethylene (LLDPE)/poly (ethylenemethyl arylate) (EMA) blends filled with carbon black (CB) are investigated in this work. Comparing to LLDPE/CB composite, the higher percolation threshold of EMA/CB composite is attributed to the good interaction between EMA and CB. However, carbon black is found to locate preferentially in the LLDPE phase of LLDPE/EMA immiscible blends from the characterization of SEM and electrical properties, which greatly decreases the percolation threshold of the composites. The viscosity of the two polymers is the key factor to determine the distribution of CB instead of interfacial energy in this system. This suggests a method to control the distribution of CB in the immiscible blends by choosing the viscosity ratio of polymer blend.

Abstract. Batteries using tonically conducting polymer membranes as electrolytes are very attractive, since the concept of power sources capable of combining a high energy content with plasticity is very appealing for the consumer electronics market and in electric vehicle applications. Blend based polymer electrolytes composed of poly (methylmethacwlate) (PMMA), Poly Vinylidene fluoride (PVdF), Lithium salt (LiX) (X = CIO4, BF 4 and CF3SO 3) and Dimethyl Phthalate (DMP) are prepared using solvent casting technique. The films have been characterized using XRD, FTIR, Thermal and SEM studies; the effect of complexing salt and temperature on ionic conductivity is also discussed. The maximum conductivity value obtained for the solid polymer electrolyte film at 303 K is 4.2 x 10 -3 S/cm.
