Novel nonammonia preservative for concentrated natural rubber latex

30-Dec-2014 | Ting Wang, Hong‐Xing Gui, Wen‐Fei Zhang, Ke‐Xi Zhang, Wei‐Qiang Yu, Yi‐Min Li, Ri‐Zhong Zeng, Mao‐Fang Huang, Journal of Applied Polymer Science, 2014

ABSTRACT A derivative of sym‐triazine (HTT) was chosen as a new nonammonia preservative for concentrated natural rubber latex (CNRL) in place of NH3–TT/zinc oxide (ZnO). The preservation effects of the HTT for CNRL, drying characteristics, mechanical properties, and cytotoxicity of the ...

Materials, Vol. 8, Pages 137-148: Preparation and Characterization of Films Extruded of Polyethylene/Chitosan Modified with Poly(lactic acid)

30-Dec-2014 | Quiroz-Castillo, Jesús Manuel; Rodríguez-Félix, Dora Evelia; Grijalva-Monteverde, Heriberto ; Lizárraga-Laborín, Lau ..., Materials, 2014

The use of mixtures of synthetic and natural polymers is a potential option to reduce the pollution by plastic waste. In this work, the method for the chemical modification of chitosan with poly(lactic acid) was developed; then, the preparation of films of blends of polyethylene and ...

Rapid formation of flexible silk fibroin gel‐like films

24-Dec-2014 | Shiyu Bie, Jinfa Ming, Yan Zhou, Tianyi Zhong, Feng Zhang, Baoqi Zuo, Journal of Applied Polymer Science, 2014

ABSTRACT Flexible silk fibroin gel‐like films with microporous morphology were prepared from B.mori silk fibroin fibers directly solubilized in formic acid/CaCl2 solvent. These films were characterized by several analysis techniques to determine the structure and properties of films. The pore ...

Impact of Molecular Architectures on the Thermal and Mechanical Properties of Multi‐Phase Polymer Networks

23-Dec-2014 | Li Wang, Ulrich Nöchel, Liang Fang, Karl Kratz, Andreas Lendlein, Macromolecular Symposia, 2014

Summary Multiphase copolymer networks (CLEG) composed of crystallizable poly(ε‐caprolactone) (PCL) and crystallizable poly(ethylene glycol) (PEG) segments can exhibit a pronounced triple‐shape effect in the dry state or a dual‐shape effect in the water swollen, hydrogel state. We hypothesize ...

Theoretical Investigation of Adhesion Properties of Polymer Coatings of Metals

23-Dec-2014 | Olga Maksimova, Andrei Maksimov, Macromolecular Symposia, 2014

Summary The models for a description of main stages of formation and adhesion processes of polymer coating on the surface of the metal were proposed. The interactions with the surface of the primer layer and the steel sheet were taken into account. On the basis of the Langmuir's lattice model ...

Theoretical Description of an Anomalous Elongation During Two‐Way Shape‐Memory Effect in Crosslinked Semicrystalline Polymers

23-Dec-2014 | Oleksandr Dolynchuk, Igor Kolesov, Hans‐Joachim Radusch, Macromolecular Symposia, 2014

Summary The present study is focused on theoretical explanation of an anomalous elongation arising during non‐isothermal crystallization of crosslinked semicrystalline polymers under constant load that represents the first stage of two‐way shape‐memory effect (SME) in these materials. The ...

Preparation of X‐ray developable LDPE/SA‐BaSO4 composites and their thermal and mechanical properties

23-Dec-2014 | Chenghao Luo, Guanyun Chen, Kongying Zhu, Xiaoyan Yuan, Polymer Composites, 2014

Low density polyethylene (LDPE)/barium sulfate (BaSO4) composites with different contents of BaSO4 nanoparticles after modification by stearic acid (SA) were prepared. Characterizations of morphology, thermal, and mechanical properties of the LDPE/SA‐BaSO4 composites were systematically ...

Thermal conductivity of epoxy resins filled with MWCNT and hydrotalcite clay: Experimental data and theoretical predictive modeling

23-Dec-2014 | Vittorio Romano, Carlo Naddeo, Liberata Guadagno, Luigi Vertuccio, Polymer Composites, 2014

In this work, the effect of hydrotalcite clay on the thermal conductivity of epoxy resin filled with carbon nanotubes (CNTs) has been studied. Thermal and morphological experiments show that the presence of hydrotalcite clay in a mesh of carbon nanotubes gives rise to aggregates and twisted ...

The effect of processing parameters on cell structure and mechanical properties of extrusion‐foamed poly(vinyl chloride) sheets

23-Dec-2014 | Mingyi Wang, Jianxiu Liu, Jun Hu, Nanqiao Zhou, Journal of Vinyl and Additive Technology, 2014

The objective of this study was to investigate the effect of processing parameters on cell structure and mechanical properties of extrusion‐foamed poly(vinyl chloride) sheets. For this purpose, the effects of screw speed and die temperature on cell morphology, density, and mechanical properties, ...
