▎ 摘　　要

NOVELTY - Conductive resin comprises 60-95 pts. wt. polymerization reaction material, 20-40 pts. wt. conductive material and 0.5-5 pts. wt. photoinitiator, where the polymerization reaction material comprises hydroxyethyl acrylate, polyethylene glycol diacrylate, polyvinyl alcohol, acrylamide and modified polydimethylsiloxane. USE - The conductive resin is used for preparing flexible and stretchable pressure sensors by 3-dimensional printing technology (all claimed). ADVANTAGE - The conductive resin cooperate with each other to form stable three-dimensional network structure through physical cross-linking and chemical cross-linking, effectively improves the mechanical properties of resin, solves the problem of uniform dispersion of conductive materials dispersed in water in resin, improves the conductive stability of conductive resin, and avoids problem of excellent mechanical properties of conductive hydrogel of similar components due to water loss, and is prepared by simple method. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the conductive resin, involving dispersing conductive material to water or ethanol to obtain dispersion liquid, and adding polymerization reaction material, uniformly mixing, heating water in mixed system and evaporating, and introducing photoinitiator to obtain conductive resin.
