Full-text available
Electromagnetic shielding has a very emerging role in the textile applications. Screen-printing is a well-known, easy and cost effective process for textile printing. In this study, carbon black and graphite particles were used to impart electromagnetic shielding property to polyester fabric by screen printing technique. To this aim, printing paste...
Article
In this paper, we investigated thermal comfort properties of twill weave cotton woven fabric coated zinc oxide layer in Roaches high temperature sample dyeing machine in gentle conditions. The effect of coated film structure on thermal comfort properties of the fabric was characterized using SEM observation, EDS analysis, and Permetest instruments....
Article
A large surface area, scalable porosity, and versatility have made nanofibres one of the most widely investigated morphologies among the nanomaterials. The characteristic properties of nanofibres have made them useful in a broad range of applications, such as filters, membranes, tissue engineering, wound dressings, protective clothing, reinforcemen...
Conference Paper
Ultrasonic coating was introduced as a simple means of functionalizing membranes and nonwovens. TiO2 nanoparticles, which have an anatase crystalline phase with superior PC activity, were directly synthesized over TPU nanofibers. Ultrasonic coating might be particularly effective for nanoparticle coatings.
Article
Solution blowing (SB) is a promising and scalable approach for the production of nanofibers. Air pressure, solution flow-rate, and nozzle-collector distance were determined as effective process parameters, while solution concentration was also reported as a material parameter. Here we performed a parametric study on thermoplastic polyurethane/dimet...
Article
The aim of this study is to investigate the effect of surface modification of fumed silica via vinyltrimethoxysilane on mechanical properties of fumed silica-unsaturated polyester composites. Modified and unmodified fumed silica-unsaturated polyester composites were prepared with the inclusion of vinyltrimethoxysilane in different (0, 0.5, 1, 1.5,...
Article
In this study, we introduce ultrasound-assisted coating as a simple means of functionalizing nanofibrous membranes for photocatalytic (PC) water filtration. TiO2 nanoparticles, which have an anatase crystalline phase with superior PC activity, were directly synthesized over TPU nanofibers and the coated membranes were characterized using scanning e...
Conference Paper
Water filtration is becoming more problematic process and gaining importance due to the lack of access to clean water. The treatment of wastewater is distinguishing process to enhance accessing to clean water. TiO2 is the mostly investigated semiconductor due to its superior photocatalytic activity. In this study, we investigated photocatalytic act...
Conference Paper
Water filtration is an important phenomena due to the lack of access to clean water. There is still a huge demand for the treatment of industrial wastewater contaminated with chemicals. TiO2 is by far the mostly investigated semiconductor for its superior photocatalytic oxidation (PCO) performance. In this study, we investigated ultrasonic radiatio...

Question
Hello,
I am trying to deposit carbon black on a flat surface via inkjet printing. I followed many methods in literature such as;
‘Elaboration of a microstructured inkjet-printed carbon electrochemical capacitor’.[Online]. Available: http://www.sciencedirect.com/science/article/pii/S0378775309015250
And
P. Kossyrev, ‘Carbon black super capacitors employing thin electrodes’, Journal of Power Sources, vol. 201, pp. 347–352, Mar. 2012.
Additionally, tried water and organic solvents; NMP, ethylene glycol, IPA, Terpineol with loading rate of carbon black varying from 1,2 mg/mL to 120 mg/mL.
To increase stability of carbon black, used dispersants such as triton x-100 and ethyl cellulose. Further, used different carbon black, 1) ketjenblack from Akzonobel, 2) Mogul E and 3) Vulcan XC72R from Cabot incorporation.
For uniform dispersion, ultrasonic irradiation with 200 W power was used. Filtration was followed to reject the particle greater than 200 nm.
However, couldn’t perform inkjet printing process.
It is clear that I couldn’t decrease particle dimension less than 200 nm. Can anyone advise how to obtain the stabilized inkjet ink having carbon black particle dimension less than 200 nm with uniform dispersion.
Thanks in advance
Regards.
Ramazan
