The SiO2-Al2O3 fiber composites had been successfully prepared by the combination technique of electrospinning and sol-gel method. The effects of Al2O3 contents (1, 2, 3, 4 and 5%wt) on fiber diameter and morphology were investigated by SEM. It was observed that alumina content significantly influenced the average diameter of fiber which increased by increasing the alumina content. The prepared fiber composites were used as a support for cobalt (Co)-based catalysts for Fischer-Tropsch synthesis (FTS). The FTS performances over the fiber and porous catalysts were carried out in a fixed bed reactor at 280°C, 1 atm, and H2/CO of 2. The results showed that the fiber catalysts were easily reduced when comparing the porous catalyst. The fiber catalysts showed the activity at the same level of the porous catalyst, but their advantage was the lower water-gas shift reaction which produced less CO2 than the porous catalyst. The CO conversion was 59.62% with the fiber catalyst and 52.80% with the porous catalyst under the same experimental condition. The fiber catalyst gave the maximum methane selectivity of 96.08% compared to the porous catalyst (85.63%). © (2015) Trans Tech Publications, Switzerland.

The development of energy‐conversion devices using water movement has actively progressed. Ionovoltaic devices, which are driven by ion dynamics, show ion specificity by which different ions with identical charges show different output performance. However, the ion specificity remains poorly understood because the influence of the ion species on generated electric signals is not elucidated. The ion specificity in electric signals induced by flowing water droplet was investigated in terms of its relationship with the potential profile across the solid–liquid interface.

A liquid crystal device which shows the capacity to perform as an electrical switchable diffraction grating is demonstrated. Periodical modulation in field-induced refractive index was realized in the in-plane switching liquid crystal device with vertical alignment, which resulted in distinct voltage-dependent diffraction patterns. © 2015 SID.

Effect of Modified Silica Particles with Phenyltriethoxysilane on Mechanical and Thermal Properties of Natural Rubber Composites

引用

Macromolecular Symposia 2015年第1期354卷 62-68页

作者： Apinya Tunlert Pattarapan Prasassarakich Sirilux Poompradub Program in Petrochemistry and Polymer Science Faculty of Science Chulalongkorn University Bangkok 10330 Thailand Department of Chemical Technology Faculty of Science Chulalongkorn University Bangkok 10330 Thailand

The modification of silica surface by phenyltriethoxysilane (PhTES) as a modifying agent was carried out by sol-gel reaction of tetraethoxysilane (TEOS) as a precursor of silica. The condition to modify silica particles was the use of the mole ratio of TEOS to PhTES of 1:0.4 and ammonia as a catalyst at ambient temperature for 24 h. The characterization of modified silica surface was investigated by a fourier transform infrared spectroscopy and contact angle measurement. The modified silica particles were in a spherical shape, which was confirmed by a scanning electron microscopy. The mechanical properties and thermal stability of modified silica particles filled NR vulcanizates were greatly improved compared to those of unfilled NR vulcanizates due to the reinforcing effect and the high thermal oxidative stability of modified silica particles, respectively.

Preparation of Green High Impact Polystyrene Beads via Suspension polymerization

引用

Macromolecular Symposia 2015年第1期354卷 69-75页

作者： Tatiya Kittiwattanakul Pattarapan Prasassarakich Napida Hinchiranan Program in Petrochemistry and Polymer Science Faculty of Science Chulalongkorn University Bangkok 10330 Thailand Department of Chemical Technology Faculty of Science Chulalongkorn University Patumwan Bangkok 10330 Thailand

The aim of this research was to investigate the important effects and their interaction on production of Green High Impact Polystyrene (HIPS) synthesized by using natural rubber (NR) as elastomeric phase via suspension polymerization initiated and stabilized by using benzoyl peroxide (BPO) and poly(vinyl alcohol) (PVA), respectively. The effects of reaction parameters: wt ratio of NR/styrene and PVA/NR including agitation rate on HIPS bead size were studied by using 2 k factorial design experiment. The HIPS bead size increased with increasing the NR content (0.01–0.08 w/w of NR/ST) in the mixture of NR/styrene syrup. Whereas, the increase in the PVA content (1.5–2.5 w/w of PVA/NR) and agitation rate (350–450 rpm) decreased HIPS bead size. Thermal gravimetric analysis (TGA) results were showed that HIPS containing the various amounts of NR had more thermal stability than the neat PS. Moreover, the glass transition temperature (T g ) of PS phase in the obtained HIPS bead was shifted from 97.9 to 84.2 °C when the wt ratio of NR/ST was increased to 0.08.

Teaching from polymer Molecular Structure to Technological Properties;Requirements in Developing Countries

引用

Macromolecular Symposia 2015年第1期355卷 32-38页

作者： North, Alastair M. Program in Polymer Science and Technology Department of Chemistry Faculty of Science Mahidol University 999 Phuttamonton 4 Road Salaya Nakon Pathom73170 Thailand

polymer Education is considered against a background of four questions. Why do we teach polymer science? To whom and by whom is polymer science taught? How can instruction in basic polymer science be related to capability in polymer technology? What aspects are important in developing countries? In developing countries innovative technological research and gathering "tacit knowledge" are needed if they are to break out of the "middle income trap". So the education of researchers, mostly in universities, as well as of those who will enter industry directly must encourage holistic thinking. polymer science is usually taught as polymer chemistry, polymer physics and polymer engineering with very little connection between them. This article suggests how a bridge of understanding, being a consideration of polymer molecular motion, can inter-relate them. © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
