Research ArticleOpen accessEvery word in the titleLiquid Crystalline Polymers Compatibilization and Adhesion Enhancement by Reactive Blending in Post-Consumers PET’sAversa Raffaella, Apicella AntonioA method for PET mechanical properties enhancement by reactive blending with HBA/HNA Liquid Crystalline Polymers for in situ highly fibrillar composites preparation is presented. LCP/PET blends were reactive extruded in presence of Pyromellitic Di-Anhydride (PMDA) and then characterized by Differential Scanning Calorimetry, Thermally Stimulated Currents and tensile mechanical properties. The formation of specific macromolecular structures, where the PET, the LCP … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 3 · 17 Jun 2016 · 8,186 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleUptake and Recovery of Lead by Agarose Gel PolymersAnurag Pandey, Anupam Shukla, Lalitagauri RayProblem statement: The uptake and recovery of lead ions were investigated by using agarose gel polymers. Approach: The experimental results showed that the agarose gel were effective in removing Pb (II) from solution. Biosorption equilibrium was approached within 4 h. Pseudo second-order was applicable to all the sorption data over the entire time range. Results: The sorption data conformed well … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 1 · 31 Mar 2009 · 7,629 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleReinforcing Effect of Strain Gauges on 3D Printed Polymers: An Experimental InvestigationSalvatore Brischetto, Roberto TorreStrain gauges are ordinary transducers for strain measuring; their operation relies on the electrical resistance, which varies as the underlying substrate is subjected to mechanical deformation. The mechanical strain can be obtained by converting the electrical signal through a gauge factor, provided by the manufacturer. It was demonstrated that its values are not unique; it may be influenced by the … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 1 · 9 Jan 2021 · 7,658 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSynthesis and Characterization of Bio-based Polyurethane PolymersJahangir Emrani, Ramazan Benrashid, Shahrzad Mohtarami et al.This paper describes the development of new biobased Polyurethanes (PU) starting from swine manure bio-resin and diisocyanates. The bio-resin is produced from swine manure via a hydrothermal process. For sustainability, today, many PUs in new specialized applications, are biobased. In this study, different commercial diisocyanates including MDI, Desmodur W, Desmodur H and Demodur I and swine manure, which is an … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 4 · 28 Nov 2018 · 8,361 accessesView PDFCite
Review ArticleOpen accessIn the keywordsA Brief Review of the Latest Advances of Attapulgite as a Reinforcing Agent in Polymer Matrix NanocompositesThais Ferreira da Silva, Gabriel Portilho Monteiro de Souza, Guilherme Ferreira de Melo Morgado et al.The development of polymeric nanocomposites using clay minerals as a Nano filler is of great interest to researchers and industry. Many clay minerals are used to modify the properties of the polymers; this strategy improves the thermal and mechanical performance and changes the surface finishing and the processing characteristics.
