Parametric study of manufacturing ultrafine polybenzimidazole fibers by electrospinning
International Journal of Plastics Technology - Tập 16 - Trang 101-116 - 2012
S. Anandhan, K. Ponprapakaran, T. Senthil, Gibin George
Polybenzimidazole (PBI), a high performance polymer, was synthesized from 3,3′-diaminobenzidine (DAB) and isophthalic acid (IPA) through polycondensation. The chemical structure of PBI was confirmed by Fourier transform infrared spectroscopy. Thermal characterization of PBI was done by thermogravimetry and differential scanning calorimetry. PBI nanofibers were fabricated by electrospinning of N, N...... hiện toàn bộ
Efficient utilization of anion exchange composites using silica filler for low temperature alkaline membrane fuel cells
International Journal of Plastics Technology - Tập 17 - Trang 35-50 - 2013
Rajangam Vinodh, Dharmalingam Sangeetha
Alkaline membrane fuel cells (AMFCs) are advantageous over polymer electrolyte membrane fuel cells (PEMFCs) in terms of electrode reaction kinetics and electrocatalyst versatility. One of the key materials for this type of fuel cell is anion exchange membrane (AEM). In this paper, we report on the fabrication of novel composite membrane from a quaternized tri-block copolymer and silica filler by s...... hiện toàn bộ
Influence of clarifying agent on the properties of polypropylene copolymer industrially injected cups for Brazilian cream cheese
International Journal of Plastics Technology - Tập 23 - Trang 170-176 - 2019
Camila F. Drummond, Mayra Stéphanie P. Damas, Claudia Merlini, Rodrigo Battisti
Aiming to achieve different characteristics with polypropylene copolymer, especially in relation to transparency similar to glass packaging, the effect of the addition of a clarifying agent derived from sorbitol to the polypropylene copolymer was studied. A specific cup shape packaging used for Brazilian cream cheese was applied. The samples were produced with different amounts of clarifying agent...... hiện toàn bộ
Numerical study on increasing PVC suspension polymerization productivity by using PSO optimization algorithm
International Journal of Plastics Technology - Tập 20 - Trang 219-230 - 2016
Reza Darvishi, Mohsen Nasr Esfahany, Rouhollah Bagheri
Despite the high application of poly (vinyl chloride) (PVC), it is still produced by batch wise rectors via suspension polymerization. Therefore, it is essential to improve the productivity of these processes by decreasing in the time of each batch maintaining desired polymer quality. The industrial batch reactors are restricted by a maximum reactor cooling capacity limiting the extent of rate of ...... hiện toàn bộ
Structural characterization and thermal decomposition of radiation induced grafting of glycidyl methacrylate onto LDPE films
International Journal of Plastics Technology - Tập 19 - Trang 178-190 - 2015
D. M. Alshangiti
The radiation initiated grafting of glycidyl methacrylate (GMA) onto low density polyethylene (LDPE) films has been investigated using a direct radiation technique. The influence of irradiation dose on the grafting yield was investigated. The grafted films were characterized to determine the structural changes with X-ray diffraction and Fourier transform infrared spectroscopy. The optical properti...... hiện toàn bộ
Thermal properties of poly (vinyl alcohol)(PVA)/halloysite nanotubes reinforced nanocomposites
International Journal of Plastics Technology - Tập 19 - Trang 124-136 - 2015
Swapna V.P., Selvin Thomas P., Suresh K.I., Saranya V., Rahana M.P., Ranimol Stephen
Natural halloysite nano clay with tubular structure was used for the preparation of polyvinyl alcohol (PVA) nanocomposites. A systematic and detailed study was conducted on the effect of nanotubes on the properties such as flame retardancy, water absorption capacity, and thermal stability of poly (vinyl alcohol) matrix. Morphological and structural characterizations of nanocomposites were performe...... hiện toàn bộ
Thermal and electrical properties of acrylic acid grafted onto starch by ceric ammonium nitrate and potassium permanganate initiator
International Journal of Plastics Technology - Tập 15 - Trang 188-198 - 2012
Jaiswar Gautam, Manoj Kumar Pal, Beena Singh, Urvi Bhatnagar
Graft copolymerization of acrylic acid (AA) onto corn starch (Starch) in aqueous media via a redox initiator system of ceric ammonium nitrate and potassium permanganate has been studied gravimetrically under nitrogen atmosphere. The grade of graft copolymers were synthesized under the effect of reaction variables such as redox initiator concentration, monomer concentration, reaction temperature an...... hiện toàn bộ

Fabrication and characterization of monomer treated sago starch film: Role of gamma irradiation
International Journal of Plastics Technology - Tập 18 - Trang 280-293 - 2014
Yasir Arafat, Pinku Poddar, Kamol Dey, Ruhul A. Khan, Mubarak A. Khan, A. M. Sarwaruddin Chowdhury
Cross linking polymerization has gained immense scientific interest to improve the performance of bio-blend film. Virgin sago starch film and its bio-blend with 2-Hydroxyethylmethacrylate (HEMA) monomer were prepared by casting method varying concentration of sago starch (100 to 93 %) and HEMA (0 to 7 %). Gamma irradiation was applied on to film to induce photo-crosslinking. Mechanical properties ...... hiện toàn bộ
Effect of maleic anhydride modified olefinic elastomer and plastomer on impact properties of PBT
International Journal of Plastics Technology - Tập 18 - Trang 157-172 - 2015
Niranjan R. Savadekar, Kedar Jadhav, Manoj Mali, S. T. Mhaske
Poly(butylene terephthalate), a polyolefinic elastomer (POE) Engage™ 8150 and polyolefinic plastomer (POP) Affinity™ 1900 were melt blended in a co-rotating twin screw extruder. Compositions having POE, POE-g-MAH, POP and POP-g-MAH up to 15 % wt with PBT were studied. The blends were characterized for mechanical, thermal and rheological properties as well as for morphological characteristics. The ...... hiện toàn bộ
