Carbon nanotube/fiber modified self-heating porous hydrophobic/oleophylic ceramic and preparation method thereof
The invention provides carbon nanotube/fiber modified self-heating porous hydrophobic/oleophylic ceramic and a preparation method thereof, wherein the self-heating porous hydrophobic/oleophylic ceramic is obtained by modifying porous ceramic, and the inner surface and the outer surface of the porous ceramic are respectively coated with a hydrophobic/oleophylic carbon nanotube/fiber layer. According to the invention, the carbon nano tube/fiber modified self-heating porous hydrophobic/oleophylic ceramic has excellent mechanical strength and chemical stability of a ceramic material, high porosity, high air permeability, good heat-conducting property and good hydrophobic and oleophylic properties. Theceramic can be self-heated under the action of an external electric field, wherein the generated heat can be quickly diffused to the surrounding high-viscosity crude oil, and the fluidity of the high-viscosity crude oil is improved, so that the high-efficiency separation of the high-viscositycrude oil is realized.
本发明提供一种碳纳米管/纤维改性的自加热多孔疏水/亲油陶瓷及其制备方法，所述自加热多孔疏水/亲油陶瓷由多孔陶瓷改性得到，在多孔陶瓷内外表面均包覆一层疏水/亲油的碳纳米管/纤维层。本发明提供的碳纳米管/纤维改性的自加热多孔疏水/亲油陶瓷具有陶瓷材料优异的机械强度和化学稳定性，孔隙率高，透气度高，导热性能好，而且具有良好的疏水亲油性，可在外加电场的作用下进行自加热，所产生的热量能快速扩散到周围的高粘度原油，增大其流动性，从而实现高粘度原油的高效分离。
