In the last decade, preparation of multifunctional composites have attracted researchers around the World for multi-purpose application. In this regard, we produced polyvinylpyrrolidone/carbon nanotubes/cotton (PVP/CNTs/cotton) nanocomposite by coating cotton fabric via pad-dry-cure under UV irradiation. Several characterization methods were used to investigate the functionality and durability including scanning electron microscopy, thermo-gravimetric analysis, flammability test, reflectance spectroscopy, tensile strength test, water absorption and antibacterial analysis. The interactions among PVP molecular chains, CNT particles and cellulose were confirmed by Raman spectroscopy. We observed a uniform coating of PVP/CNTs on the fiber surface. An advantage of our developed method was the strong interfacial interaction among compositions, high durability along with multifunctional properties. PVP/CNT nanocomposite was able not only to improve the thermal stability of cotton, but also provided a reduced flammability and good antibacterial properties. Here, we confirm a simple and versatile method for fabrication of PVP/CNTs/cellulose nanocomposite for multi-purpose applications. [ABSTRACT FROM AUTHOR]
