Preparation and Application in Flexible Sensing Field of G-Eco-AAc/OTF Composite Conductive Hydrogel
As high performance polymer material,conductive hydrogels are widely used in the field of flexible sensors and energy storage equipment.Nevertheless,most conductive hydrogels are single-layer structure and exhibit weak mechanical property.The composite layer hydrogels can achieve complementary mechanical properties through the bonding between each layer.Therefore,hydrogels need to be designed from the structure to improve mechanical property for more function.Herein,G-Eco-AAc/OTF composite layer hydrogel with adhesion,mechanical tensile properties and electrical conductivity is prepared.The graphene layer,Ecoflex elastomer and AAc/OTF hydrogel are polymerized in situ polymerization.In the presence of carboxyl,hydroxyl and sulfonic acid groups,the hydrogel exhibits excellent adhesion.The G-Eco-AAc/OTF composite layer conductive hydrogel is applied as human motion sensor,which could monitor the movement signals of fingers,wrists,elbows and knees.The test results are stable.This composite conductive hydrogel lays the foundation for the next generation of wearable flexible sensing devices.
