Abstract
A fully recyclable high-strength epoxy polymer includes a first monomer containing two or more epoxy groups, a second monomer comprising a sulfur-containing aliphatic carboxylic acid, and a third monomer acting as a catalyst. The epoxy polymer is synthesized through dual dynamic reactions using the third monomer that facilitates a reaction between the epoxy groups of the first monomer and both ends of the aliphatic carboxylic acid of the second monomer.
Claims16
A fully recyclable high-strength epoxy polymer comprising:
- a first monomer containing two or more epoxy groups;
- a second monomer comprising a sulfur-containing aliphatic carboxylic acid;
- and
- a third monomer acting as a catalyst,
- the epoxy polymer being synthesized through dual dynamic reactions using the third monomer that facilitates a reaction between the epoxy groups of the first monomer and both ends of the aliphatic carboxylic acid of the second monomer.
A method for producing a fully recyclable high-strength epoxy polymer, comprising:
- a step of preparing a transparent solution by mixing and heating a first monomer and a second monomer;
- a step of preparing a mixture by adding a third monomer to the transparent solution, followed by stirring;
- a step of pre-curing the mixture by heating after pouring the mixture into a mold;
- and
- a main curing step of curing the pre-cured mixture by heating in a vacuum.
