Effects of production parameters on the structure of resol type phenolic resin/layered silicate nanocomposites

Polymer/layered silicate nanocomposites belong to one of the most promising group of materials of the past few decades and most probably for the near future. Following the pioneering works of Toyota Research Group in the 1980s, the interest on these materials increased rapidly and research is now being carried out world wide, using all kinds of polymers as base material.


Effect of fused deposition modeling process parameters on the mechanical properties of recycled polyethylene terephthalate parts
Bakir, Ali Alperen; Atik, Resul; Özerinç, Sezer (Wiley, 2020-08-01)
Fused deposition modeling (FDM) filaments made of recycled materials are desirable for environmentally friendly and sustainable manufacturing of prototypes and load-bearing components in many applications. We investigate the effect of FDM process parameters on the mechanical properties of 3D-printed parts made of recycled polyethylene terephthalate (rPET) filaments. Increasing the nozzle temperature from 230 degrees C to 260 degrees C improves the strength of the specimens by 100%. Using a raster orientatio...
Effect of CNTs dispersion on electrical, mechanical and strain sensing properties of CNT/epoxy nanocomposites
Tanabi, Hamed; Erdal Erdoğmuş, Merve (Elsevier BV, 2019-03-01)
The remarkable electrical and mechanical properties of carbon nanotubes (CNTs) render CNT-reinforced nanocomposites as potentially attractive materials for strain-sensing and monitoring purposes. The dispersion state of CNTs in polymeric matrix has a significant role on the physical and the mechanical properties of the resulting CNT reinforced nanocomposites. In this study, a series of experiments were designed to investigate the effect of dispersion process parameters and CNT concentration, as well as thei...
Effect of a carbon black surface treatment on the microwave properties of poly(ethylene terephthalate)/carbon black composites
Koysuren, Ozcan; Yesil, Sertan; Bayram, Göknur; Secmen, Mustafa; Aydın Çivi, Hatice Özlem (Wiley, 2008-07-05)
A surface treatment was applied to carbon black to improve the electrical and microwave properties of poly(ethylene terephthalate) (PET)-based composites. Three different formamide solutions with 1, 2, and 3 wt % concentrations were prepared to modify the surface chemistry of carbon black. Microwave properties such as the absorption loss, return loss, insertion loss, and dielectric constant were measured in the frequency range of 812 GHz (X-band range). Composites containing formamide-treated carbon black e...
Effect of surface treatment on electrical conductivity of carbon black filled conductive polymer composites
Koysuren, Ozcan; Yesil, Sertan; Bayram, Göknur (Wiley, 2007-06-05)
Two different types of surface modifiers, 3-aminopropyltriethoxysilane and formamide, were applied to carbon black (CB) particles to lower electrical resistivity of polymer composites prepared by treated CB. Two different matrices, low-density polyethylene and nylon 6, were chosen to compound with surface modified CB. Surface energy of CB was increased by adding amine or amide functional groups during surface treatment of CB. According to electron spectroscopy for chemical analysis (ESCA), chemical modifica...
Effect of stabilizer on the catalytic activity of Kobalt(0) Nanoclusters catalyst in the hydrolysis of Sodium Borohydride
Koçak, Ebru; Özkar, Saim; Department of Chemistry (2009)
The development of new storage materials will facilitate the use of hydrogen as a major energy carrier in near future. Among the chemical hydrides used as hydrogen storage materials for supplying hydrogen at ambient temperature, sodium borohydride seems to be an ideal one because it is stable under ordinary conditions and liberates hydrogen gas in a safe and controllable way in aqueous solutions. However, self hydrolysis of sodium borohydride is so slow that requires a suitable catalyst. This work aims the ...
