Preparation method of epoxy resin base micron to nano grade pore gelatin

This invention involves a preparation method for epoxy resin-based gel with micron to nanometer holes. The said method includes dissolving epoxy resin and amines such as diethylene triamine and triethylene tetramine in a certain weight in the polyethylene glycol solution, polymerizing to form a white gel, curing, and removing polyethylene glycol to obtain gel with micro/nano-holes. The whole preparation process is environmental-friendly. The gel can be prepared in arbitrary shape with uniform pore size distribution and adjustable size. The gel has strong hydrophilicity and resistance to acid, alkaline and solvent. There are large amounts of reaction functional groups, which can functionalized channels through chemical modification. The gel can be widely applied to separation, filtration, adsorption, and chelation in equipment analysis, water treatment and biomedical industries, such as microfiltration membrane and smart membrane, heavy metals removal, the stationary phase of chromatography column, enzyme immobilization, cell culture, drug sustained-release, chemical sensors, etc.
