How to prepare polyacrylamide gel electrolytes with high ionic conductivity?

Polyacrylamide gel polymer electrolytes with high ionic conductivity were prepared by a free radical polymerization method. An electrochromic device (ECD) based on a n in situ polymerized polyacrylamide gel electrolyte was assembled. The ECD has large optical modulation, fast response and maintain 90.6% of optical modulation after 13,500 cycles.

Is polyacrylamide a good electrolyte layer?

Polyacrylamide (PAM) GPE has very high transparency and ionic conductivity, as well as good flexibility and mechanical properties, making it an ideal choice for electrolyte layers of ECDs [, , , ].

What is a cross-linked polyacrylamide electrolyte?

A cross-linked polyacrylamide electrolyte with high ionic conductivity for compressible supercapacitors with wide temperature tolerance Jin, X., Sun, G., Zhang, G. et al. A cross-linked polyacrylamide electrolyte with high ionic conductivity for compressible supercapacitors with wide temperature tolerance.

What is polyacrylamide?

Polyacrylamide is a term that has various definitions. For our purposes here, we will simply term polyacrylamide as a polymer that contains an acrylamide monomer at some level. Polyacrylamides make up the largest group of polymers in comparison to other synthetic polymeric polyelectrolytes.

How is polyacrylamide a hydrolyzed polymer?

The process generally involves the addition of a strong base to a homopolymer of polyacrylamide. This can be done in an aqueous solution, inverse emulsion. Recently, a process to produce dry forms of hydrolyzed polyacrylamide has been developed. This allows for the preparation of very high-molecular-weight anionic polymers.

What is a hydrogel polyelectrolyte?

Herein, a highly conductive and compressible hydrogel polyelectrolyte has been prepared from polyacrylamide cross-linked by methacrylated graphene oxide (MGO-PAM) and the polyelectrolyte can maintain its excellent elasticity at −30 °C as well as its original shape at 100 °C.
