| titleOfInvention | Porous impact-resistant TPU composite pressure sensing material, preparation method and application |
| abstract | The invention discloses a preparation method of a porous impact-resistant TPU composite pressure sensing material, which comprises the following steps: (1) preparing thermoplastic polyurethane, a conductive material and an organic solvent into a uniform mixed solution; (2) treating the mixed solution by a steam-induced phase separation method to obtain a formed TPU composite pressure sensing material; (3) and washing the formed TPU composite pressure sensing material for multiple times by using alcohol, then washing the TPU composite pressure sensing material for multiple times by using water, and then freeze-drying the washed TPU composite pressure sensing material to obtain the porous impact-resistant TPU composite pressure sensing material. In the mixed solution in the step (1), the mass-to-volume ratio of the TPU to the organic solvent is 1g: (1-10) mL. The porous impact-resistant TPU composite pressure sensing material disclosed by the invention has good mechanical properties, high sensitivity factor and excellent impact-resistant energy-absorbing performance. The preparation method has the advantages of simple process, high quality controllability and low production cost. |
