The method for producing electrically conductive fabrics with the addition of graphene ink, developed by an international team of scientists, opens up new frontiers for the development of flexible wearable electronics without additional expensive toxic processing.
This is a joint project of scientists from the Cambridge Graphene Center and China's Jiangnan University. They have developed a technology for applying graphene ink to cotton to create conductive textile materials.
The new technology was developed by Dr. Felice Torrisi and his team. The ink is based on chemically modified graphene flakes with high adhesion - the ability to stick. After heat treatment, the conductivity of the modified graphene increases. The application of graphene to cotton fabrics can be compared to their usual dyeing with colored dyes.
The choice of cotton fabrics as the basis for wearable electronics is due to their advantages - they are well ventilated, comfortable to wear and durable. According to scientists, graphene ink can withstand several washes.
Wearable electronics based on graphene fabric will allow the creation of complete flexible electronic circuits. The invention will find applications in health and environmental monitoring, energy conversion, and many other areas.
