Abstract

The invention discloses a preparation method of a conductive oil gel. The preparation method comprises the following steps: dissolving purified aniline and 3-aminophenylboronic acid monohydrate in a mixed solution to make the molar amount of 3-aminophenylboronic acid be 0.06 mmol and the molar amount of aniline be 1 mmol; adding 3 mL of an aqueous polyvinyl alcohol solution with a concentration of10 wt%, and performing stirring until uniformity is achieved in order to obtain a mixed solution; and mixing an oxidizing agent solution with the mixed solution at -4 DEG C, and standing the obtainedsolution for 12 h. The conductive oil gel of the present invention has the best compression performance in oil gels ontaining an antifreeze agent. The conductive oil gel also has self-healing ability, and keeps stable properties such water content and flexibility for a long term in the room temperature environment.

Description

technical field [0001] The invention belongs to the gel field, in particular to a conductive oil gel and a preparation method thereof. Background technique [0002] Over the past few decades, hydrogel-based materials have gained extensive attention. Among them, conductive hydrogels combine the conductive properties of hydrogels and conductive polymers, as well as hydrophilicity and biocompatibility, and have many applications. However, hydrogels inevitably lose elasticity and conductivity below zero. , severely restricting its practical application at low temperatures. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, prepare a conductive oil gel system with antifreeze / water as a binary dispersion medium, and improve the electrical and mechanical properties of the composite gel system. [0004] The specific technical solutions are: [0005] A preparation method of conductive oil gel, comprising the ...
