Embodiment 1

[0044] A preparation method of a double-network sulfonated polyphenylene ether / acrylate elastomer composite material, comprising the following steps:

[0045] 1) Preparation of sulfonated polyphenylene ether: add 95 g of chloroform and 5 g of PPO (polyphenylene ether) to a 250 mL three-necked flask, and uniformly stir at room temperature to form a homogeneous solution. Pipette an appropriate amount of chlorosulfonic acid (the molar ratio of polyphenylene ether and chlorosulfonic acid is 3:4), dilute it with chloroform into a solution of a certain concentration, cool it in an ice-water bath, and then transfer it to a constant pressure dropping funnel to start dropping , After the dropwise addition, the reaction was continued at room temperature for 1 h. The resulting product was washed with deionized water, and after lyophilization for 24 h, the sulfonated polyphenylene ether was prepared.

Abstract

The invention discloses a preparation method of a dual network sulfonated polyphenyl ether / acrylic composite material. The composite material is composed of a double-layer network, wherein the first layer is a network formed by crosslinking of sulfonated polyphenyl ether and an acrylate monomer; and the second layer is a network formed by crosslinking of metal ions and sulfonate of sulfonated polyphenyl ether. The preparation method of the dual network composite material comprises the following steps: S1) dissolving sulfonated polyphenyl ether, the acrylate monomer, a cross-linking agent and an initiator in a solvent and carrying out a polymerization reaction to obtain organogel; and S2) mixing the organogel and an ionic compound solution to carry out an ionic crosslinking reaction. By constructing the multi-layer network structure in the acrylate elastomer, strength of the material is enhanced; and through dissipation of energy by ionic bond rupture, toughness of the material is enhanced. According to the prepared dual network sulfonated polyphenyl ether / acrylic composite material, strength is enhanced while toughness is correspondingly increased.

Description

technical field [0001] The invention belongs to the field of polymer materials, in particular to a preparation method of a double-network sulfonated polyphenylene ether / acrylate composite material. Background technique [0002] High strength and high toughness of materials are often difficult to coexist. For example, increasing the degree of cross-linking of elastomers can increase the strength of the material but will cause the material to become brittle and reduce its toughness. There is still no good way to increase the strength of the material without sacrificing the ductility and toughness of the material. The traditional method is to fill the polymer material with fillers such as nanofibers, but it is still unable to fundamentally change the contradiction between increasing the strength of the material and reducing the toughness. A recent approach is to fabricate interspersed structures with double or triple networks through intricate network structures, energy dissip...
