Abstract

The invention relates to the field of novel material preparation and specifically relates to a preparation method of a novel soluble polyaryletherketone material. The preparation method of the novel soluble polyaryletherketone material, disclosed by the invention, comprises the following steps: firstly, synthesizing a sulfonyl-containing diphenol monomer in a dimethylsulfoxide solvent by using 2,7-naphthalenediol and dichlorodiphenylsulfone under the catalysis of potassium hydroxide and potassium carbonate; and polymerizing the monomer and 1,4-bis(4-fluorobenzoyl)benzene under the catalysis ofa mixed catalyst, namely potassium carbonate and sodium carbonate, to generate a novel polyaryletherketone material of which a molecular chain contains naphthyl and sulfonyl. The material disclosed by the invention not only is a novel polymer material with good performances and can meet different use demands, but also can remarkably improve the solubility of a polyaryletherketone polymer and ensure that the polymer is dissolved into various strong-polarity organic solvents such as NMP, DMAc and chloroform, so that the material is expected to be used as a film or a coating to be applied to thefield such as microelectronics.
