Essential work of fracture analysis of short glass fiber and/or calcite reinforced ABS/PA6 composites
11-05-2013 | Sinan Yilmaz, Taner Yilmaz, Biricik Kahraman, Polymer Engineering and Science, 2013
Abstract The effect of reinforcing agent type and composition on the fracture behavior of short glass fiber (SGF), CaCO3 particle, and glass fiber/CaCO3 hybrid reinforced ABS/PA6 blend based composites have been studied by using the essential work of fracture (EWF) method. Two millimeter ...
Effect of interfacial interactions on the crystal growth rate in model PE/SiO2 nanocomposites: Comparing experiments with lauritzen‐hoffman model and MD simulation
11-05-2013 | J. Jancar, R. Balkova, Polymer Engineering and Science, 2013
Abstract Nanoparticles with engineered surface chemistry represent novel means in controlling the in‐situ formation of property‐specific supramolecular structure in advanced processing technologies of semicrystalline polymers. Often, the published experimental data on effects of ...
The viscoelastic behavior of concentrated polyacrylonitrile/1‐butyl‐3‐methylimidazolium chloride from solution to gel
11-05-2013 | Xinjun Zhu, Hina Saba, Yumei Zhang, Huaping Wang, Polymer Engineering and Science, 2013
Abstract The viscoelastic behavior of concentrated polyacrylonitrile (PAN) /1‐butyl‐3‐methylimidazolium chloride ([BMIM]Cl) solutions at different concentrations and temperatures has been investigated by rheology. For concentrated polymer solutions at low temperature (40°C), the shear ...
Fabrication and characterization of poly(methyl methacrylate)/CaCu3Ti4O12 composites
11-05-2013 | P. Thomas, R.S. Ernest Ravindran, K.B.R. Varma, Polymer Engineering and Science, 2013
Abstract Composites comprising Poly(Methyl Methacrylate) (PMMA) and CaCu3Ti4O12 (CCTO) via melt mixing followed by hot pressing were fabricated. These were characterized using X‐ray diffraction, thermo gravimetric, scanning electron microscopy, and Impedance analyzer for their structural, ...
Control of the mechanical and thermal properties of semicrystalline polymers via a new processing route of the equal channel multiple angular extrusion
11-05-2013 | V.A. Beloshenko, A.V. Voznyak, Y.V. Voznyak, Polymer Engineering and Science, 2013
Abstract Deformation routes of equal‐channel multiple angular extrusion (ECMAE) are suggested that allow realization of new combinations of positions of planes and directions of simple shear. The routes are called F, B+C, D+C. Their effect on the structure and the properties of ...
Preparation and characterization of PPy doped with different anionic surfactants
10-05-2013 | Mei Li, Wenguang Li, Jun Liu, Jinshui Yao, Polymer Engineering and Science, 2013
Abstract Polypyrrole (PPy) was successfully prepared by chemical oxidation in various anionic surfactant solvents and an interesting regulation of the molar ratio of the oxidant and the monomer was firstly discovered which was closely related to the conductivity of the PPy when the molar ...
Synthesis, characterization, and properties of new conducting polyaniline/copper sulfide nanocomposites
10-05-2013 | M.T. Ramesan, Polymer Engineering and Science, 2013
Abstract This article reports the facile synthesis of copper sulfide (CuS)/polyaniline (PANI) nanocomposites by in situ polymerization. The composites were characterized by scanning electron microscopy (SEM), UV–visible and Fourier transform infrared (FTIR) spectroscopy, X‐ray diffraction ...
Preparation and characterization of chitosan‐stearate complexes and in vitro evaluation on the adsorption of deoxycholic acid salt
10-05-2013 | Yiyu Xu, Yanshun Xu, Jiali Zhang, Wenshui Xia, Polymer Engineering and Science, 2013
Abstract Chitosan‐stearate complexes (CSC) were prepared by reacting chitosan (CS) with stearic acid. The formation and characteristics of CSC were studied by FTIR spectroscopy, X‐ray diffraction (XRD), and thermogravimetric analysis (TGA). The results showed that the complexes were ...
Preparation of a versatile precursor of novel functionalized polymers: the influence of polymerization conditions on the structure of poly [1‐(2‐hydroxyethyl)aziridine]
10-05-2013 | Asta Šakalytė, José Antonio Reina, Marta Giamberini, Albena Lederer, Polymer Engineering and Science, 2013
Abstract The cationic polymerization of 1‐(2‐hydroxyethyl)aziridine was approached by means of several catalytic systems under various conditions in order to obtain a versatile hydroxylated starting material for chemical modification reactions. Largely regular polymers were obtained using ...
Copolymers based on epoxidized soy bean oil and diglycidyl ether of bisphenol a: Relation between morphology and fracture behavior
10-05-2013 | Facundo I. Altuna, Valeria Pettarin, Loli Martin, Aloña Retegi, Iñaki Mondragon, Roxana A. Ruseckaite, Pablo M. Stefani, Polymer Engineering and Science, 2013
Abstract Epoxidized soybean oil (ESO) was proved to be a good alternative to partially replace a synthetic commercial epoxy resin in a formulation to obtain thermosetting polymer, contributing to transform a vegetable oil into a higher added value product. This work focuses on the study ...
