Abstract

The invention discloses a photo-electromagnetic response epoxy glass polymer which is prepared from the following components in parts by weight: 50-100 parts of epoxy resin, 20-60 parts of an epoxy curing agent, 0-30 parts of an epoxy diluent, 5-100 parts of inorganic filler and 0-5 parts of a catalyst. The photo-electromagnetic response epoxy glass polymer can drive reversible exchange reaction of dynamic ester bonds or disulfide bonds, exchange of polymer chain segments and recombination of a cross-linked network under specific laser, voltage/current or alternating magnetic fields, so that repair and welding of the epoxy glass polymer under various external stimulations of photo-electromagnetism are realized.

Description

technical field [0001] The invention belongs to the field of macromolecule materials, and in particular relates to an epoxy-type glass macromolecule with photoelectromagnetic response. Background technique [0002] Epoxy polymers, as a typical thermosetting polymer, have been widely used because of their excellent mechanical properties, excellent structural stability and good solvent resistance. However, when fully cured, the epoxy forms a three-dimensional cross-linked network, becoming a bulk cross-linked structure with a fixed shape and no further deformation. Unlike thermosetting polymers such as epoxy, thermoplastic polymers such as linear or branched polyethylene or polypropylene can be flowed and molded multiple times in solvents or at high temperatures, but their mechanical properties, structural stability, heat resistance and Solvent resistance is far inferior to thermoset polymers such as epoxy. [0003] In this paper, in order to make epoxy polymers take into ac...
