Abstract
Textile article comprising a textile substrate to which graphene is applied in an amount from 0.5 to 20 g of graphene per square meter of textile substrate, wherein said graphene is dispersed in a polymeric binder and forms a thermal circuit heatable by exposure to electromagnetic radiation. There is also described a filter comprising said textile article, for example a face mask for personal health protection.
Claims20
A textile article comprising:
- a textile substrate having a bacterial filtration efficiency of less than 80% prior to the application of graphene;
- and
- a polymeric binder with graphene in an amount from 0.5 to 20 g of graphene per square meter of textile substrate for forming an electric and thermal circuit heatable by Joule effect with an external battery or by exposure to electromagnetic radiation in the infrared or microwave region,
- wherein the graphene has a C/O ratio of >100:1 and is in the form of nano-platelets, and the textile article after application of graphene has a bacterial filtration efficiency greater than 80%.
