Chitosan and its derivative carboxymethylchitosan were combined in a solution to create a natural amphoteric polyelectrolyte hydrogel film, which was then cross-linked with glutaraldehyde. Such a hydrogel swiftly bends in the direction of one electrode in response to an electric shock, demonstrating electrical sensitivity.
Because of its amphoteric nature, the hydrogel bends either toward anode or cathode, depending on the pH of the electrolyte solution. Along with pH, other elements that affect the electromechanical behavior of hydrogels include ionic strength, electric field strength, hydrogel thickness, and the quantity of cross-linking agent.
The chitosan/carboxymethylchitosan hydrogel has superior overall mechanical properties and electrical sensitivity when compared to the chitosan/carboxymethylcellulose hydrogel that we previously reported, indicating its great potential for microsensor and actuator applications, particularly in the biomedical sector.
Electroactive hydrogel is one sort of intelligent (smart) hydrogel, which may swell, shrink or bend under electric input. Electroactive hydrogels have a wide range of potential uses in the field of smart gel-based devices, including sensors, artificial muscles, film separation tools, and drug delivery systems.
This is because they can directly convert electrical energy into mechanical work. Electroactive hydrogels have been produced using a variety of synthetic polymers, including sulfonated polystyrene, acrylic acid/vinyl sulfonic acid copolymer, and polyvinyl alcohol.
In addition to synthetic polymers, some natural polyelectrolytes have been blended with synthetic polymers to prepare such hydrogels.
The Global Electroactive hydrogel market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
RTP Company launched Electroactive hydrogel Earlier electroactive hydrogel limitations are addressed by the current invention. In contrast to prior art hydrogels, the electroactive polymer hydrogels offered by the current invention, among other things, contract quickly and bend more easily and to a greater extent.
By including porous scaffolds in the hydrogels, the electroactive polymer hydrogels of the present invention have been engineered to maximize electroactuation. It is thought that the porosity in the hydrogels of the present invention reduces the cross-sectional area of the hydrogel, requiring less COOH groups on the anode side of the hydrogel to produce a bending motion, without intending to be limited by theory.
