“…Considering that the highest increase in hydrophobicity was observed after plasma treatment in oxygen-containing process gas, oxidation processes with actively involved oxygen appear to play an important role in the formation of hydrophobic functional groups on the cellulose surface. Presented results correspond to our previous studies [ 66 , 78 , 79 ] and the findings reported in [ 80 ] that noble gases, such as argon, show a reduced capability in HMDSO dissociation compared to oxygen.…”

The aim of this work is to design and optimize the process of functionalization of cellulose fibers by organosilane functional groups using low-pressure microwave plasma discharge with hexamethyldisiloxane (HMDSO) precursor in order to prepare a compatible hydrophobic filler for composites with nonpolar thermoplastic matrices. Particular attention was paid to the study of agglomeration of cellulose fibers in the mixture with polypropylene. In our contribution, the dependence of the surface wettability on used process gas and treatment time was investigated. Scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS) analyses were applied to characterize the surface morphology and chemical composition of the cellulose fibers. It was observed that the plasma treatment in oxygen process gas led to the functionalization of cellulose fibers by organosilane functional groups without degradation. In addition, the treated cellulose was highly hydrophobic with water contact angle up to 143°. The use of treated cellulose allowed to obtain a homogeneous mixture with polypropylene powder due to the significantly lower tendency of the functionalized cellulose fibers to agglomerate.

Surface Area Evaluation of Electrically Conductive Polymer-Based Textiles

In this paper, the surface area of coated polymer-based textiles, i.e., copper and nickel plated woven polyester fabric, copper and acrylic coated woven polyester fabric, and copper and acrylic coated non-woven polyamide fabric, is investigated. In order to evaluate the surface area of the woven fabrics, Peirce’s geometrical model of the interlacing point and measurement using an electron microscope are used. Non-woven fabrics are evaluated using an optical method, handmade method, and MATLAB functions. An electrochemical method, based on the measurement of the resistance between two electrodes, is used for relative comparison of the effective surface area of the coated woven and non-woven fabrics. The experimental results show that the measured and calculated warp lengths do not differ within the standard deviation. The model for the surface area evaluation of the Pierce’s geometrical model for monofilament (non-fibrous) yarns is extended to multifilament yarns and to a uniform sample size. The experimental results show the increasing trend of surface area evaluation using both modeling and electrochemical methods, i.e., the surface area of the copper and acrylic coated woven Polyester fabric (PES) is the smallest surface area of investigated samples, followed by the surface area of the copper and acrylic coated non-woven fabric, and by copper and nickel plated woven PES fabric. These methods can be used for surface area evaluation of coated polymer-based textiles in the development of supercapacitors, electrochemical cells, or electrochemical catalysts.

This paper discusses the emerging technologies to produce uniform films of functional materials on textiles. These include development of nano-coatings and micro-scale coatings using physical vapor deposition, atomic layer deposition, chemical vapor deposition techniques, and layer-by-layer deposition on textile substrates. Functionalities are added by these processes to textiles such as electromagnetic shielding, antibacterial efficacy, heat or UV radiation resistance, electrical conductivity, soil and oil release, self cleaning, chemical resistance and flame retardancy, with minimum effect on the strength, handle or comfort properties.Keywords: Chemical vapor deposition, layer-by-layer deposition, physical vapor deposition, surface functionalization of textiles.
