Latest Patents

Wenji Zheng holds a patent for a "Large-scale fabrication technique for PIM-1 asymmetric membranes doped with low-molecular-weight polyethylene glycol for gas separation." This patent outlines a fabrication technique that includes several key steps. Firstly, the coagulation process of the casting solution is regulated by polyethylene glycol to thin the dense layer. This improvement enhances the hydrophilicity of the membrane structure and forms mass transfer channels for the diffusion of polyethylene glycol into the dense layer. Subsequently, directional migration and enrichment of polyethylene glycol are achieved through capillary action induced by directional water evaporation. This process results in the fabrication of PIM-1 asymmetric membranes doped with polyethylene glycol in the dense layer, specifically designed for gas separation.
