Poly(N,N-dimethyl)acrylamide-based ion-conductive gel with transparency, self-adhesion and rapid self-healing properties for human motion detection

Abstract

Flexible strain sensors have been extensively studied for their potential value in monitoring human activity and health. However, it is still challenging to develop multifunctional flexible strain sensors with simultaneously...

Transparent ionic conductive elastomers with high mechanical strength and strong tensile properties for strain sensors

“…55 When in contact with the skin, the carbonyl groups and carboxyl groups on the skin surface generate dipolar–dipole interactions and hydrogen bonding with CO and –OH in the elastomer, respectively, which allows the elastomer to adhere tightly to human skin. 41,53…”

“…55 When in contact with the skin, the carbonyl groups and carboxyl groups on the skin surface generate dipolar-dipole interactions and hydrogen bonding with CQO and -OH in the elastomer, respectively, which allows the elastomer to adhere tightly to human skin. 41,53 Self-healing properties of PDES-DMA elastomers Gently make physical contact between the two sliced ionic conductive elastomers and take an optical image of the healing portion using an optical microscope (Fig. 5a).…”

“…Based on this, in this study, we prepared a PDES-DMA ionic conductive elastomer by rapid in situ photopolymerization based on poly(N,N-dimethyl acrylamide) (PDMA), which has good self-adhesion, 40,41 biocompatibility 42,43 and good compatibility with AA/ChCl-type PDES. Compared with the reported methods, this method has the following advantages: (1) the preparation process of ionic conductive elastomers is simple and fast, requiring only ''one-step'' photoirradiation polymerization (UV irradiation for 30 s); (2) in addition to simultaneously having a strong tensile strength (9.27 MPa) and high elongation at break (1072%), the prepared ionic conductive elastomer also has high transparency (480%), strong adhesion (133.8 kPa adhesion to the glass surface) and self-healing properties.…”

Bio-based monomers for amide-containing sustainable polymers

“…Poly( N -isopropylacrylamide) is a temperature-responsive polymer with pendant secondary amides. 5 Poly(2-oxazoline), 6 poly(vinylpyrrolidone), 7 and poly( N , N -dimethyl acrylamide) 8 contain tertiary amide groups and exhibit unique properties when compared to those with primary or secondary amides. Currently, synthetic amide-containing polymers are mostly produced from petroleum-based monomers.…”
