Abstract

The invention relates to the field of sponge materials. In order to solve the problems of preparation of conductive sponges in the prior art, or problems of environmental pollution and hard brittleness, the present invention provides a preparation method of a polyaniline modified foam sponge. The preparation method comprises the following steps: 1) weighing and proportioning 50 to 100 parts by weight of an aniline modification liquid, 3.5 to 4.2 parts by weight of a buffer agent, and 15 to 18.5 parts by weight of an accelerator according to 100 parts by weight of a sponge matrix; and 2) addingthe buffer agent to the aniline modification liquid, placing the sponge matrix in the aniline modification liquid, heating the aniline modification liquid to 45 to 65 DEG C in a water bath, then slowly adding the accelerator, allowing the mixture is to stand and conducting drying to obtain the polyaniline modified foam sponge. By introducing the aniline modification liquid, a conventional spongecan be effectively subjected to conductivity treatment, so that the sponge has good electrical conductivity while maintaining the elasticity and flexibility.

Description

technical field [0001] The invention relates to the field of sponge materials, in particular to a polyaniline modified foam sponge. Background technique [0002] With the rapid development of modern technology and the improvement of living standards, high-tech products are more and more favored by people, bringing people convenience in life and spiritual enjoyment, but the resulting electromagnetic radiation is also becoming more and more serious , Anti-electromagnetic radiation has also become an environmental protection topic that people are more and more concerned about. The most convenient and effective way to prevent electromagnetic radiation is to use electromagnetic shielding, that is, to use metal mesh with good electrical conductivity and magnetic conductivity to block electromagnetic radiation through reflection and absorption effects. The spread of radiation. Conductive sponge is a material that integrates conduction and electromagnetic shielding functions. It is...
