High-performance triple-crosslinked polymer and preparation method thereof

A method for preparing a high-performance triple-crosslinked polymer comprising the following steps:

• (1) mixing a monomer having two epoxy groups, a cross-linking monomer and a functional monomer to obtain a mixture, then dissolving the mixture in a predetermined amount of a solvent to obtain a mixed solution, and stirring the mixed solution evenly, and
• (2) filtering the mixed solution obtained in step (1) to obtain a filtered mixed solution, then pouring the filtered mixed solution on a clean flat glass, and curing the filtered mixed solution at 60-180° C. and 0-450 Torr for 3-12 hours,
• wherein
• the high-performance triple-crosslinked polymer is obtained by cross-linking a monomer having two epoxy groups, a cross-linking monomer, and a functional monomer;
• a molar ratio of the monomer having the two epoxy groups, the cross-linking monomer, and the functional monomer is 10:(2.5-4.5):(1-5);
• the high-performance triple-crosslinked polymer contains a cross-linking network formed by three bonds including a covalent bond, a first hydrogen bond, and a second hydrogen bond;
• and
• the first hydrogen bond and the second hydrogen bond have different strengths.
