The quality, structural defects, and transport properties of GO can be tailored by maintaining ultrasonic bath temperature. Herein, the effect of temperature-controlled exfoliation on the structural defects and transport properties of the resulting graphene oxide (GO) sheets are examined. The large crystallite size (12.23 nm) and low defect density (2.16 x 10(11) cm(-2)) are found at 20 degrees C exfoliations. Highly oriented GO sheets were exfoliated at 20 degrees C which was confirmed through Bernal-stacking proportions (similar to 30%). Furthermore, electrical transport properties are high at 10 degrees C exfoliation temperature while optimum at other temperatures, calculated through impedance spectroscopy. Comparatively, smooth, wrinkle-free, and lesser bulges are found at 20 degrees C and 30 degrees C exfoliation temperatures.
