Enhanced current response and humidity sensitivity of PANI/Gr composite on porous polyurethane.AbstractRecent advancements in organic materials based sensor technology created a prospective field in designing sensors that are both cost?effective and environment friendly. In view of that an electronic material system has been prepared depositing a uniform layer of graphite?infused Polyaniline (PANI) onto the sponge framework using a straightforward physical vapor deposition technique. The prepared active materials were studied for the composition, morphology, optical properties, and charge transport characteristics. In the current context of rapidly growing sensor technology, this works describes an innovative approach of improving the response of the prepared electronic system of PANI/Gr composites, integrated into porous PU sponge substrates. Incorporation of graphite in PANI improved the electrical conductivity of the composite and porous structure of PU increased the interaction surface area. The performance of the prepared materials in humidity detection was evaluated by studying their resistive response under varying humidity levels, which was measured through current?voltage (I?V) characteristics. The higher interaction sites of the reported active sensing system leads to inspiring humidity sensitivity of 0.522–26.22?k?/% RH with reasonable response and recovery time of 572 and 416?sec respectively. Additionally, the reported sensor system consisting of degradable materials will offer a useful way of reducing electronic garbage.
