The method developed by an international team of scientists to produce electrically conductive tissues with the addition of graphene ink opens new boundaries for the development of flexible portable electronics without additional expensive toxic treatment.
This is a joint project of scientists from the Cambridge Center of Graphene and the Chinese University of Jiangnan. They 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 basis of the ink is chemically modified graphene flakes, which have 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 with their usual painting with colored dyes.
The choice of cotton fabrics as a 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 create full-fledged flexible electronic circuits. The invention will find application in monitoring health and the environment, energy conversion , and in many other areas.
