Strain Sensors Based on Electroless Ni-P Plated Polyester Woven Fabrics
Mostafa Youssefi,Elaheh Fanaei,Mohsen Shanbeh 한국섬유공학회 2019 Fibers and polymers Vol.20 No.3
In this study, polyester and polyester/spandex woven fabrics were electroless Ni-P plated at different conditions. The physical and electrical properties of Ni-P coated fabrics were investigated by scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), wide angle X-ray scattering (WAXS), tensile tests, and air permeability, hydrophobicity and cyclic electro-mechanical measurements (strain sensor evaluation). SEM, WAXS and EDX results revealed the existence of an amorphous layer consisting of Ni and phosphorous atoms on the surface of the fabrics. Besides, the coated fabrics became more hydrophobic than the raw fabrics and the air permeability of them was also decreased. The electroless plated polyester fabrics showed some regular variation of resistance versus time during cyclic loading under 25 % strain, with very distinct maximums and minimums in the resistance/time curves. This trend was not observed for polyester/ spandex coated fabrics due to its mechanism of deformation under strain. As a conclusion, the polyester Ni-P electroless plated fabrics could be considered as strain fabric sensors that might be applied in smart textiles.
