Abstract
Nanocomposites of various conducting polymers and porous silicon have been successfully fabricated by the electrochemical and spin coating techniques. Porous silicon template was firstly synthesized by the galvanostatic anodization of silicon wafer in HF-based solution, followed by the electrochemical polymerization of polypyrrole (PPy), polyaniline (PAn) and polythiophene (PTh). The results of the electropolymerization reveal that the polymers are infiltrated homogeneously inside the nanopores. The deposition starts from the pore bottom and propagates towards the pore opening. The deposition of Poly(2methoxy-5-(2-ethyl-hexyloxy)-1,4-phenylene-vinylene) MEH-PPV was also performed into the porous silicon matrix using the spin coating technique. As-formed nanocomposites have been fully characterized using various techniques including, SEM, XRD, FTIR. The photoluminescence behavior was examined and evaluated.
