چکیده
A new hydrophobic hexyltrimethoxysilane (HTMS) coating for polyester fabric was successfully synthesized via a one-step water-based sol-gel method under acidic condition. Five different molar ratios of HTMS: water (1;40, 1:30, 1:20, 1:12 and 1:3) were prepared the solution deposited onto by simple dip-pad-cure process. The effect content on hydrophobicity evaluated manual testing treated samples. effectiveness properties further characterized using contact angle (WCA) measurement. optimized ratio 1:3 found to obtain best property 136.2° with particle size 115.3 µm measured Particle Size Analyzer (PSA). Fourier transform infrared spectroscopy (FTIR) analysis confirmed success sol gel process presence Si-O-Si band, which also determined energy dispersive X-ray (EDX). Scanning Electron Microscopy (SEM) images revealed good surface morphology homogenous thin xerogel no visible cracks. Using HTMS without combinations other precursors resulted in rough structure due low caused long-chain alkyl silane this provided hydrophobicity. Doi: 10.28991/esj-2021-01309 Full Text: PDF

Sericin based bioactive coating for polyester fabric
In this study, a process has been developed for durable coating of sericin on polyester. Pre modification of polyester with alkali (sodium hydroxide) has been carried out to incorporate polar entities on its inert surface. 10g/L of sericin with 30mL/L of glutaraldehyde, cured at 130°C for 2min has been optimized for its application on modified surface. Treated samples are tested for surface smo...
متن کاملPTEE Based Water Repellent Coating for Telecommunication Antennas
Since thick snow or ice adhering to the surface of an antenna used for radio communication can impede telecommunication [1], methods to reduce the buildup of snow and ice are needed. Various methods have been investigated. For example, the adhesion of ice to common rubber has been measured [2], and recently, a method that takes advantage of the physicochemical properties of material surfaces ha...
متن کاملFunctional polyester fabric through simultaneous aminolysis and nano ZnO synthesis
Here, in situ synthesis of nano zinc oxide, along with aminolysis of polyester fabric, has simultaneously been carried out by using triethanol amine (TEA) and zinc acetate. The ZnO nano particles (NPs) were formed and stabilized on the fabric surface by amine compound at 130 °C for 1 h. The synthesis of nano ZnO particles on the polyester fabric were confirmed by X-ray diffraction (XRD) pattern...
