    Printed Textiles with Chemical Sensor Properties
    (Instytut Biopolimerów i Włókien Chemicznych (IBWCh) , Łódź, Polska, 2014) Krucińska, Izabella; Skrzetuska, Ewa; Urbaniak-Domagała, Wiesława
    In this study the authors proposed the introduction of chemical sensors directly on textile surfaces in the form of conductive transmission parts using the screen-printing technique. A liquid vapour-sensitive, printing surface made with the use of multi-walled carbon nanotubes was also evaluated. Carbon nanotubes show effective chemo-sensory properties because the chemical agent leads to changes in electrical conductivity. The research concerned the assessment of sensor efficiency for chemical incentives in the form of selected fluids and their vapours. The best sensory properties were observed for polar vapour at a level of relative resistance over 40%. In the case of vapours of non-polar fluids the sensory reaction of the printed fabrics is much weaker – at a level of relative resistance of about 25%. The printed textile backings subjected to the influence of a fluid show an immediate reaction, while in the case of fluid vapour the reaction occurs after a few seconds. Detection of the presence of dangerous chemical agents such as organic liquids and their vapour is possible by means of a structure composed of sensors.

    Chemically Driven Printed Textile Sensors Based on Graphene and Carbon Nanotubes
    (MDPI, 2014) Skrzetuska, Ewa; Puchalski, Michał; Krucińska, Izabella
    The unique properties of graphene, such as the high elasticity, mechanical strength, thermal conductivity, very high electrical conductivity and transparency, make them it an interesting material for stretchable electronic applications. In the work presented herein, the authors used graphene and carbon nanotubes to introduce chemical sensing properties into textile materials by means of a screen printing method. Carbon nanotubes and graphene pellets were dispersed in water and used as a printing paste in the screen printing process. Three printing paste compositions were prepared—0%, 1% and 3% graphene pellet content with a constant 3% carbon nanotube mass content. Commercially available materials were used in this process. As a substrate, a twill woven cotton fabric was utilized. It has been found that the addition of graphene to printing paste that contains carbon nanotubes significantly enhances the electrical conductivity and sensing properties of the final product.
