Fabrication of piezoresistive based pressure sensor via purified and functionalized CNTs/PDMS nanocomposite: Toward development of haptic sensors

摘要

Graphical abstractThe effect of pressure and the range of resistance in nanocomposites could vary drastically depending on the treatment of nanomaterials prior to fabrication.Display OmittedHighlights?The significance of purification on quality and properties of CNTs.?The importance of functionalization for homogenous dispersion of CNTs in PDMS.?The significance of processing CNTs prior to use, on the electrical properties, range of output signal and lowering the percolation threshold.?Increase in CNTs weight fraction results in decrease in electrical resistance as a function of pressure in nanocomposite, at above 15wt%.?Better understanding the mechanism and nature of CNTs/PDMS nanocomposite.
