Synthesis of gelatin and green tea based stretchable self-healing material of biomedical importance

摘要

Stimuli-responsive stretchable self-healing hydrogels of bio-based origin have gained extreme importance for the development of materials possessing numerous applications related to wound healing, preparation of electronic skin and many health monitoring issues. This paper highlights the synthesis of novel self-healing, stretchable hydrogel derived from gelatin and aqueous green tea extract (Gel-(ox)GT(p-phen)). The hydrogel Gel-(ox)GT(p-phen) was found to be biodegradable in phosphate buffer, urea solution and solutions of different pH. The synthesized material exhibited viscoelastic and self-healing properties. Self-healing occurred in the material after 2 h. Lastly, the blood containing Gel-(ox)GT(p-phen) hydrogel sample exhibited 1.47 percentage hemolysis ratio indicating non hemolytic nature of the synthesized hydrogel and practical utility in the biomedical field.
