- Abstract:
- In this paper, the graphene (G) /thermoplastic polyurethane (TPU) /polydimethylsiloxane (PDMS) conductive polymer composites(CPCs) with conductive fibrous network s were prepared by the electrostatic spinning and spraying technology, and their strain sensing behaviors were studied in detail. The CPCs possess large elongation at break (165%). With the strain increasing , the sensitivity increases gently at first , and when the strain is greater than 50%, the sensitivity increases sharply, which shows a positive response between strain and sensitivity. Meanwhile, the CPCs exhibit weak hysteresis effect and stable resistance-strain sensing response behavior during the cyclic stretching, which is attributed to the encapsulation of PDMS . For the cyclic resistance-strain sensing curve s, the CPCs show good response stability under different strain amplitudes. The G/TPU/PDMS CPCs reported in this paper have brilliant application prospects in the field of flexible wearable electronics.
