Suvrajyoti Mishra, Lakshmi Unnikrishnan, Sanjay K. Nayak, Smita Mohanty
AbstractPolymeric piezoelectric composites for energy harvesting applications are considered a significant research field which provides the convenience of mechanical flexibility, suitable voltage with sufficient power output, lower manufacturing cost, and rapid processing compared to ceramic‐based composites. This review focuses majorly on the basic theory and pri...... hiện toàn bộ Chemical Recycling of Poly(ethylene terephthalate) Tập 292 Số 2 - Trang 128-146 - 2007

AbstractThis paper covers the recent research carried out by the authors on the chemical recycling of poly(ethylene terephthalate) (PET) taken from post‐consumer soft‐drink bottles. The chemical recycling techniques used are critically reviewed and the authors' contribution is highlighted. Hydrolysis in either an alkaline or acid environment was employed in order t...... hiện toàn bộ Quality Concepts for the Improved Use of Recycled Polymeric Materials: A Review Tập 293 Số 4 - Trang 274-297 - 2008

AbstractPolymeric waste materials should be considered resources for the manufacture of new products through recycling processes, with a similar status to virgin fossil‐based plastics and biopolymers from renewable resources. Several efforts can be made to achieve this qualitative quantum leap in plastics recycling, and consequently introduce recycled products, wit...... hiện toàn bộ Additive Processing of Polymers Tập 293 Số 10 - Trang 799-809 - 2008

AbstractAdditive processing technologies are rapidly growing in all fields of application. A large number of scientific publications were investigated in order to provide a comprehensive overview of rapid prototyping methods for polymers and their applications, of currently available materials and research concerning additive processes. The current problems of addi...... hiện toàn bộ Physico‐Mechanical Properties of Biodegradable Starch Nanocomposites Tập 294 Số 3 - Trang 169-177 - 2009

AbstractNanocomposites of cassava starch reinforced with waxy starch nanocrystals were prepared. They showed a 380% increase of the rubbery storage modulus (at 50 °C) and a 40% decrease in the water vapor permeability. X‐ray spectra show that the composite was more amorphous than the neat matrix, which was attributed to higher equilibrium water content in the compo...... hiện toàn bộ Polyurethanes Based on Castor Oil: Kinetics, Chemical, Mechanical and Thermal Properties Tập 293 Số 11 - Trang 922-929 - 2008

AbstractPolyurethanes based on vegetable oil were synthesized with castor oil and toluene diisocyanate, isophorone diisocyanate or hexamethylene diisocyanate, using dibutyltin dilaurate as a catalyst. The effects of the nature of the diisocyanate on the evolution of the kinetics, as well as the physical and mechanical properties and the thermal stability, of the di...... hiện toàn bộ
