Superoleophobic thin films have many potential applications including fluid transfer, fluid power systems, stain resistant and antifouling materials, and microfluidics among others. Transparency is also desired with superhydrophobicity for their numerous applications; however transparency and oleophobicity are almost incompatible relationship with each other in the point of surface structure. B...

Complex permittivity of conducting polypyrrole (PPy)-coated Nylon-Lycra textiles is measured using a free space transmission measurement technique over the frequency range of 1-18 GHz. The aging of microwave dielectric properties and reflection, transmission and absorption for a period of 18 months is demonstrated. PPy-coated fabrics are shown to be lossy over the full frequency range. The leve...

The newly identified natural fabric from the tree of Sterculia urens was coated with Polymethyl methacrylate. The tensile properties of both the uncoated and Polymethyl methacrylate coated fabrics were studied. The tensile parameters such as maximum stress, Young’s modulus and % elongation at break were determined using a Universal Testing Machine. The effect of alkali treatment and the Polymet...

Wool textiles have been coated with nordihydroguaiaretic acid (NDGA) to improve their performance at use. This water insoluble phenolic compound has been grafted on wool through a laccase enzyme catalyzed reaction in an 80/20 (v/v, %) aqueous-ethanol mixture. The capacity of laccase to oxidise NDGA in this aqueous-organic medium has been studied electrochemicaly. FTIR spectra, together with the...

The paper describes the electrical plant response to mechanical stimulation monitored with the help of conducting polymers deposited on cotton fabric. Cotton fabric was coated with conducting polymers, polyaniline or polypyrrole, in situ during the oxidation of respective monomers in aqueous medium. Thus, modified fabrics were again coated with polypyrrole or polyaniline, respectively, in order...

In the present study, the inherent characteristic of carbon nanotubes to absorb/attenuate the energy of electromagnetic waves has been exploited. The results indicate that the incorporation of CNTs in the polyurethane matrix has significant effect on the microwave interaction properties. Fabrics are developed through coating process using formulations based on different concentrations of multi ...

Our research was focused on the evaluation of the photocatalytic and antimicrobial properties, as well as biocompatibility of cotton fabrics coated with fresh and reused dispersions of nanoscaled TiO₂-1% Fe-N particles prepared by the hydrothermal method and post-annealed at 400 °C. The powders were characterized by X-ray diffraction (XRD), Mössbauer spectroscopy and X-ray photoelectron spectro...

BACKGROUND The use of clothing as a means of sun protection has been recommended in recent education campaigns. Contrary to popular opinion, however, some fabrics provide insufficient ultraviolet (UV) protection. MATERIAL AND METHODS We investigated 236 apparel textiles of the spring/summer collections 2000 and 2001. In accordance with the forthcoming European standard the UV protection facto...

cotton/polyester knitted fabrics as a major production of textile industry was treated with titanium dioxide nanosized particles. the treated fabric with nanosized tio2 became whiter with a good self-cleaning property. also the discoloration of reactive black 5 dye was studied and reported. the stabilization of tio2 on cotton/polyester knitted fabrics by citric acid (ca) with sodium hypophospha...
