Flexible Conductive CNT/poly (vinyl chloride) Composite Thin Films with High Mechanical Strength and Thermal Stability
Annubhawi Annu, Amit Sachdeva
The fabrication and characterization of ultrathin composite films of surfactant-wrapped CNT nanoflakes and poly (vinyl chloride) is described. Free-standing composite thin films were prepared by a simple solution blending; drop casting and annealing route. A significant enhancement in the mechanical properties of pure poly (vinyl chloride) films was obtained with a 2 wt. % loading of CNT; such as a 58 % increase in Youngs modulus and an almost 130 % improvement of tensile strength. Thermal analysis of the composite films showed an increase in the glass transition temperature of the polymer; which confirms their enhanced thermal stability. The composite films had very low percolation threshold of 0.6 vol. % and showed a maximum electrical conductivity of 0.058 S/cm at 6.47 vol. % of the CNT loading.
