[Abstract]:Three-dimensional porous conductive material is a new material with excellent electrical and mechanical properties. The direct infiltration method based on porous material template has the advantages of simple process and low cost. It is a promising method for the preparation of three-dimensional porous conductive materials. It is of practical significance to study the tactile sensor based on three-dimensional porous conductive material for developing a new tactile sensor and widening its application field. In this paper, three dimensional assembly of carbon black and graphene biphase conductive filler was guided by polyurethane sponge as template and coated with nano-size slurry. PUS-CB/GNPs/SR and PDA-PUS-CB/GNPs-SR composites with double network structure were fabricated by layer-by-layer assembly method. The microstructure of porous composites was analyzed by scanning electron microscope and Fourier transform infrared spectroscopy (FTIR). The influence of the structure size of the template on the mechanical properties was studied. The effects of the two-phase packing, the three-dimensional sponge skeleton, the concentration of conductive filler, the modification and the preparation method on the electrical and mechanical properties of the porous elastomer were analyzed. The process parameters of high performance porous conductive sponge composites were optimized. A small range tactile sensor with high sensitivity and flexibility based on PDA-PUS-CB/GNPs-SR conductive sponge was designed and fabricated. The anti-interference property of the tactile sensor based on three-dimensional conductive sponge to environmental temperature and humidity was studied. The sensor is integrated into the larynx, the back of the hand and the phalanx to realize tiny tactile perception (2kPa) by using the signal acquisition and processing system at the back end of the sensor. The results show that the small range tactile sensor can be widely used in electronic skin and wearable devices, and has great potential application value in the future.
