Thermal Analysis of Polyurethane Coatings Modified with Graphene and Modification Influence on Mechanical Properties of Hybrid Textile Materials Dedicated to Personal Protective Equipment
Source abstract
Abstract
This paper is focused on the modification of polyurethane coating applied to the outer layer of hybrid textile materials dedicated to personal protective equipment. For this purpose, graphene with various weight fractions, i.e., 0.25 and 0.5 wt.%, was introduced into the polyurethane matrix. The prepared pastes were applied to meta-aramid fabric as coating. The results of the thermogravimetric analysis of polymer coating showed a shift in the onset temperature of the polymer coating to higher values after graphene addition, which indicates an improvement in thermal stability. Considering mechanical properties, the implementation of the coating on meta-aramid fabric reduces tear resistance but this may be improved by the addition of 0.5 wt.% of graphene. Such a hybrid textile material meets the tearing force requirements for protective clothing for firefighters according to EN 469:2020.
