Recent Progress of Polyurethane-Based Materials for Oil/Water Separation
Gailan Guo,Libin Liu,Zhao Dang,Wenyuan Fang 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2017 NANO Vol.12 No.4
With the development of society, oil pollution has become more and more serious, it is becoming a global issue to separate oil and water mixture. Currently, a variety of functional materials have been successfully prepared for oil/water separation. Among them, polyurethane is an attractive candidate due to its low cost, wear-resistance and excellent mechanical properties. This report summarizes the design strategy of polyurethane-based materials and their applications in oil/ water separation. The progress made so far will guide further development of polyurethane-based materials for oil/water separation.
Investigation of grafted sulfonated alkali lignin polymer as dispersant in coal-water slurry
Yanlin Qin,Dongjie Yang,Wenyuan Guo,Xueqing Qiu 한국공업화학회 2015 Journal of Industrial and Engineering Chemistry Vol.27 No.-
A novel grafted sulfonated alkali lignin polymers (GSAL) with hydrophilic side chain and differentmolecular weights prepared were used as dispersants for coal-water slurry (CWS). The viscosityreduction for CWS had been attributed primarily to the diminution of coal particles (adsorbed GSAL)interaction of steric electrostatic repulsion and dramatic wettability. The adsorption amount of GSAL-3can reach to 1.58 mg/g, and the isotherm of GSAL on coal surface belongs to the Langmuir model, theelectrostatic self-assembly result indicated the dominant driving force of GSAL absorbed on coal surfacewas the p–p interaction. GSAL was superior in reducing the viscosities of CWS.
