Abstract: To develop conductive and self-healing hydrogels with excellent mechanical properties for the application in flex-sensor, the novel HP (AA-co-AM) gels containing both hydrophobic association and hydrogen bonding were successfully synthesized. The hydrogels were fabricated by photoinitiated micellar polymerization technique, using acrylamide (AM) as the main hydrophilic monomer, acrylic acid (AA) as the modified hydrophilic monomer, stearyl methylacrylate (SMA) as hydrophobic monomer and I2959 as the photo-initiator in the solution of salt (NaCl) and sodium dodecyl sulfate (SDS). The results showed that the addition of AA strengthened the intermolecular hydrogen bond, which significantly improved the mechanical properties of the gel, with tensile strength up to 0.46 MPa. Meanwhile, the intermolecular hydrogen bond was reversible and leaded to a better self-healing performance of the gels. The strain-electric conductivity of the gels was measured and it was found that the gels exhibited sensitive tensile strain-resistance variation and good repeatability and stability in human limb activities. The synthesized gels could be a promised new material in the field of self-healing electronic skin for the flex-sensor.
