| Description | The work is focused on preparation of novel polymer memristors that will be able to mimic neurosynaptic functions. A memristor is a passive electronic component that changes its value depending on its history (the charge passed). One of its very attractive aspects is that both the storage and processing of information can be done within a single element. Memristors change their response to a test voltage according to the voltage they have been previously exposed to. This dependence on voltage history can be exploited in an ensemble of circuit elements to construct adaptive network systems, or to mimic a synaptic neural network with synaptic plasticity. Experimental and theoretical approach will be used to study novel materials with donor and acceptor pendant groups. Mechanisms important for the charge carrier transport through these pendant groups will be elucidated. Both the polymers with saturated and unsaturated backbone will be prepared. In the former ones the transport is expected to be controlled by an external electrical field, in the latter ones the possibility of the synergic effect of the charge transport through the conjugated backbone and redox mechanism of the charge transport through the pendant groups will be tested. New polymers and polymer composites will be prepared with built-in chemical groups sensitive to the applied electric field or to the transported charge. By changing the spatial molecular arrangement or charged state of the molecular building blocks the electrical resistance will be controlled. Suitable for students with completed master studies in physical chemistry, polymer and chemical physics. |
