氧化石墨烯-酚醛树脂薄膜的制备及性能研究

The Preparation and Properties of Graphene Oxide Sheets/Phenolic Resin Composites

采用化学分散法大量制备氧化石墨烯,并采用直接共混法制备氧化石墨烯/酚醛树脂纳米复合材料。通过AFM、SEM、FT-IR、TG等对其进行表征,结果表明,氧化石墨烯完全剥离,并在基体中分散均匀,而且两者界面相容性好,提高了复合材料的热稳定性。通过高温热处理使复合材料薄膜在兼顾形貌的同时实现导电,当氧化石墨烯含量为2%(质量分数)时,其导电率为96.23S/cm。

Graphenc oxide sheets（GOs） are prepared in large amount by traditional chemical dispersion method,and then GOs/water soluble PF resin（WPF） nanocomposites are prepared by directly blending method.AFM,SEM,FT-IR,TG are amployed to characterise these composite membranes.The results suggest that GOs is exfoliated totally and distributes well in the matrix ,and the interface between GOs and WPF of the composites is quite compatible,In addition ,TGA of the composites membranes sample proves that the thermal stabillty of WPF is remarkably Improved after composlting with GOs Via treated by earboniastion ,elestrical conductivity of the membrane inereses while retaining its shape,The grapheme based membrane has a conductivity of 96.238/cm when it with 2wt% GOs concentration.
