Multifunctional Cotton Fabrics Produced in Iran Using Nanotechnology

Tehran, Iran | Posted on October 2nd, 2014

The nanocomposite creates important characteristics in the fabrics, including self-cleaning, antibacterial and electrical conduction properties.

Fabrics made of cotton have desirable properties for clothes, including high sorption ability, respiration ability, comfort and softness. However, the application of these fabrics in various industries is limited due to their low mechanical properties, high flammability, easy growth of microorganisms due to high adsorption of humidity and their becoming dirty easily. Therefore, it is vital to carry out special complementary processes to improve the properties of cotton fabrics, such as increasing self-cleaning, thermal resistance, antibacterial activity and mechanical behavior. In this research, the effect of the application of graphene/titanium dioxide nanocomposite has been studied for the first time on improving the properties of cotton fabrics.

According to the researchers, the coating of cotton fabrics with graphene/titanium dioxide nanocomposite has created fabrics with perfect photocatalytic properties under the radiation of ultraviolet and visible light. The fabrics have fantastic electrical conduction and antibacterial activity and it has been confirmed that they are non-toxic. The interesting point is that the produced fabric in this research is multifunctional and can be used in various industries.

Graphene has been used in this research as the second part of the composite (titania is the first part) to settle the problems and create high performance photocatalyst. The nanocomposite is highly capable of absorbing paints and organic materials and has wide light attraction zone and high electron transfer ability. Higher efficiency and activity at visible light are the advantages of the produced nanocomposite over titanium dioxide.

Results of the research have been published in Cellulose, vol. 21, issue 5, 2014, pp. 3813-3827.
