采用热冲击非溶剂诱导相分离(TINIPS)方法首次制备了具有新型微纳尺度二元结构的超疏水、超亲油多孔氧化石墨烯/聚碳酸酯(RGO/PC)整体。由于其独特的孔结构，多孔整体具有较高的比表面积(137.19 m2/g)和孔隙率(91.3%)。超疏水RGO/PC整体柱具有良好的选择性吸附水中多种油和有机溶剂的能力。此外，该整体可保持对腐蚀性介质(例如，酸性和碱性溶液)的稳定排斥。基于这些优异的性能，多孔RGO/PC整体柱将成为处理水污染的高效油水分离材料。
Superhydrophobic and superoleophilic porous reduced graphene oxide/polycarbonate (RGO/PC) monoliths with novel micro-nanoscale binary structure were first fabricated by thermally impacted nonsolvent induced phase separation (TINIPS) method. Owing to the unique pore structure, the porous monoliths possessed high specific surface area (137.19 m2/g) and porosity (91.3%). The superhydrophobic RGO/PC monoliths exhibited excellent capability to selectively adsorb a wide range of oils and organic solvents from water. Furthermore, the monoliths could keep a stable repellency against corrosive mediums (e.g., acidic and alkali solutions). Based on these superior properties, porous RGO/PC monoliths will be a promising candidate for high-efficiency oil/water separation to deal with water pollution.
