Abstract

The invention provides organic hydrogel with adjustable mechanical properties as well as a preparation method and application thereof. The method comprises the following steps of adding a monomer, a cross-linking agent and a cross-linking accelerant into a composite solvent, and oscillating and dissolving to obtain a first solution, adding an initiator into the composite solvent, and oscillating and dissolving to obtain a second solution, adding the second solution into the first solution, and curing and molding to obtain organic hydrogel, wherein the monomer comprises one of acrylamide, acrylic acid and N-isopropylacrylamide, the composite solvent is formed by mixing alcohol and water, and the alcohol comprises at least one of ethylene glycol, glycerol, hexanehexol, polyethylene glycol and polyvinyl alcohol. The mixture of alcohol and water is used as the composite solvent, and the mass ratio of alcohol to water and the mass ratio of alcohol to water to acrylamide are adjusted, so that the mechanical properties of the obtained organic hydrogel can be adjusted.

Description

technical field [0001] The invention relates to the technical field of preparation of flexible materials, in particular to an organic hydrogel with adjustable mechanical properties and a preparation method and application thereof. Background technique [0002] Hydrogel is one of the most promising soft materials, widely used in drug controlled release, polyelectrolyte, ion touch panel, etc. Generally, the mechanical properties of hydrogels have a great influence on the performance of flexible electronic devices, while the conventional hydrogels prepared with water as a solvent have fragile mechanical properties; currently, there is a lack of research on hydrogels with adjustable mechanical properties.
