(a) Thermal conductivity of drawn pure PVA-0 without SDBS (red block) and thermal conductivities of PVA-0(2), PVA-1, PVA-2, and PVA-5 films, each containing 1 wt % SDBS with an increasing GO content. (b) Thermal conductivities of drawn PVA-5(2), PVA-5, and PVA-5(3) films containing variable concentrations of SDBS with 5 wt % of GO. (c) Photographs of undrawn (i) and drawn (ii) PVA-5 films and the OM image (iii) of drawn PVA-5 films. (d) Thermal conductivities reported for different films in the literature.9,10,13,15,16,23−30 The x axis represents the wt % contents of the thermally conductive additives. The red symbols represent drawn polymers or composites. Here, GN, RGO, GT, CNT, and PVDF represent graphene, reduced graphene oxide, graphite, carbon nanotube, and polyvinylidene fluoride, respectively.
