Fabrication of Conductive Porous Structure Loaded With Carbon Black and/or Carbon Nanotube

Abstract

Carbon black (CB) and/or carbon nanotube (CNT) loaded porous PP frame with enhanced conductivity was facilely fabricated via immiscible co-continuous polymer blend and subsequent dissolution process. The SEM result indicated that the agglomerated carbon additives formed continuous phase on the inner wall of the interconnected micro channel. Nitrogen gas adsorption test was carried out to characterize the nano pores resulted from these nano particles. In addition, the electrochemical performance of the material was evaluated by cyclic voltammetry and galvanostatic charge-discharge cycling. Experimental results demonstrate the effectiveness of this novel method to construct conductive material with hierarchical porous structure which integrates co-continuous porous structure with nano pores derived from deposited carbon additives.
