Preparation and characterization of Thermal-responsive Cotton-graft Poly(N-isopropylacrylamide) Fabrics via Ar Plasma
(0) Thermosensitive functional textile is a self-adjustable cloth which adapts to suit under special climate and geographical environment based on temperature change.It is mostly prepared from phase change materials.Poly(N-isopropylacrylamide) has a thermoresponsive phase transition:at 32℃ water-insoluble (hydrophobic) and water-soluble (hydrophilic) states interconvert.Introduced PNIPAAm into textile,can not only improve mechanical performance of PNIPAAm,but also endow with conventional textile special thermo-responsive property.In this paper,a novel thermo-sensitive switching fabric has been prepared by Ar-plasma-induced simultaneous grafting Ploy-N-isopropylacrylamide (PNIPAAm) onto cotton fabric.The factors affecting the degree of grafting,such as the discharge power,discharge time and argon current pressure,were studied.Fourier transform infrared spectroscopy (FTIR) was used to identify the structure of the grafted fabric.Then the surface morphology of the grafted fabric was observed from scanning electron microscopy (SEM).The FTIR and SEM results show that the PNIPAAm was grafted onto cotton fabric,respectively.The thermal properties of different yield Cotton-g-PNIPAAm fabrics are characterized by differential scanning calorimetric analysis (DSC).The DSC analysis results indicated that LCST value of the grafted fabric was about 32~33.And water ℃ flux was also measured using home-made water-flux device.It was proved that grafted fabric was sensitive to temperature.
