Latest Patents

One of his latest patents is titled "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 regulates the coagulation process of the casting solution using polyethylene glycol. This method improves the hydrophilicity of the membrane structure and forms mass transfer channels for the diffusion of polyethylene glycol into the dense layer. The technique also involves directional migration and enrichment of polyethylene glycol through capillary action induced by directional water evaporation.

Another notable patent is the "Method for preparing zeolite CHA membrane." This method employs a gel conversion technique to assist in crystallization. It involves successively coating seed solutions of varying concentrations and sizes on a porous support to create a seed layer. A synthetic gel is then applied to this layer, followed by a membrane crystallization reaction to produce a zeolite CHA membrane. This innovative approach bypasses the conventional stage of converting heterogeneous zeolite into zeolite CHA seed, allowing for a more direct preparation process.
