Abstract

We replicate the unique pore structure of ion-track etched polymers with carbon using an organic sol-gel precursor strategy. First, phenol resin is cross-linked in the membrane pores, followed by selective dissolution of the template matrix and carbonization at a temperature of 550 degrees C. The potential to create nanomaterials of novel morphology is demonstrated by synthesizing free-standing, interconnected networks composed of aligned carbon nanowires of defined or modulated diameter.
