The memristive resistor has been a long time candidate for the artificial neural network as it has similar short-term plasticity and long-term potentiation as neuro synapse. Recent works on resistive switching access memory give the confidence to achieve computation on the memristive device. Most efforts have been worked on regular resistor network which needs complex lithographic technology. Here we propose a simple approach with functionalized polyaniline complex network. PANI is a widely used conductive polymer which is flexible and stable in the air but does not have switching behavior. 1/f noise measurement shows PANI network is scale-free, which has also been found in our brain. We firstly functionalized PANI with gold nanoparticles(GNP) to form GNP/PANI fibers. GNP/PANI film has been proved to have bistable switching behavior. Our I-V measurement on GNP/PANI nanofibers shows similar bistable switch behavior. Test of the memristive efficiency on our complex network is on the going.
