Research Progress of Self-healing Graphene-based Flexible Sensors
The self-healing flexible sensor has good susceptibility,mechanical properties and self-healing proper-ties.Compared with the traditional flexible sensor,it can repair the damage caused by deformation and has a long service life.Graphene-based composites with excellent mechanical properties and high electrical conductivity have been widely used in the field of self-healing flexible sensors.This paper focused on the self-healing mechanism of the graphene based flexible sensor,that is,self-healing based on reversible covalent bonds,including Diels-Alde (D-A) reaction,reversible disulfide bond,reversible borate bond,and reversible non-covalent bond,such as hy-drogen bond,metal coordination bond and double dynamic reversible bond.The paper summarized matrix materials for preparing the sensor,which are mainly polydimethylsiloxane,polyurethane,polyacrylic acid,polyvinyl alcohol,etc.And it compared the properties of the self-healing graphene-based sensors prepared by different matrix materi-als.Finally,it discussed the existing problems of the self-healing graphene-based flexible sensor and its future de-velopment.
