Parametric study of manufacturing ultrafine polybenzimidazole fibers by electrospinningInternational 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 cellsInternational 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 cheeseInternational 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

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 initiatorInternational 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
Optimization of reaction condition for carboxylicpropyl starch from potato starchInternational Journal of Plastics Technology - Tập 22 - Trang 104-114 - 2018
Nisarg K. Prajapati, N. K. Patel, Vijay Kumar Sinha
Starch from potato was converted to carboxypropyl starch (CPS) by etherification using Monochloropropanoic acid and sodium hydroxide. The reaction was optimized against temperature, concentration and reaction time. The optimizedproduct has a large degree of substitution of 0.734, which compared favorably to other forms of starch. Fourier Transform Infrared spectra were used to characterize the pro...... hiện toàn bộ
