Facile preparation of silver/reduced graphene oxide/chitosan colloid and application of the nanocomposite in antibacterial and catalysis

12-Jan-2018 | Jing An, Guizhen Guo, Rong Yin, Qingzhi Luo, Xueyan Li, Fan Liu, Desong Wang, Polymer International, 2018

Abstract Reduced graphene oxide (RGO) decorated with silver nanoparticles (AgNPs) were synthesize by a facile solution‐based approach in chitosan (CS) solutions. The morphology and elemental composition of as‐prepared Ag/RGO/CS colloid were characterized by scanning electron microscopy (SEM) ...

Effect of Matrix‐Nanoparticle Supramolecular Interactions on Morphology and Mechanical Properties of Polymer Foams

12-Jan-2018 | Seifollah Jamalpour, Seyed Reza Ghaffarian, Amir Jangizehi, Polymer International, 2018

In this study, we report fabrication of supramolecular polymer nanocomposite foams with uniform cell structure, high cell density, and expansion ratio using a soft matrix of poly (MA‐co‐HEMA) and silica nanoparticle fillers, both functionalized with Ureido‐ Pyrimidinone (UPy) supramolecular ...

Effect of polystyrenes with different architecture on β nucleating efficiency and toughening of isotactic polypropylene

12-Jan-2018 | Jingru Liu, Chen Li, Fangming Hu, Polymer International, 2018

Abstract The effect of polystyrenes with different architecture (three‐arm star‐shaped polystyrene (sPS), comb‐like branched polystyrene (cPS) and linear polystyrene (lPS)) on their β nucleating efficiency for isotactic polypropylene (iPP) during crystallization and final impact and tensile ...

Thiol‐ene photofunctionalization of 1,4‐polymyrcene

12-Jan-2018 | Aleksandar Matic, Helmut Schlaad, Polymer International, 2018

ABSTRACT 1,4‐Polymyrcene was synthesized by anionic polymerization of β‐myrcene and was subjected to photochemical functionalization with various thiols (i.e., methyl thioglycolate, methyl 3‐mercaptopropionate, butyl 3‐mercaptopropionate, ethyl 2‐mercaptopropionate, and ...

Rheo‐Raman Spectroscopic Study of Microscopic Deformation Behavior for Ultra Low‐Density Polyethylene (ULDPE)

09-Jan-2018 | Takumitsu Kida, Yusuke Hiejima, Koh‐hei Nitta, Polymer International, 2018

Abstract In situ Raman spectroscopy was applied to ultra low‐density polyethylene (ULDPE) to investigate the microscopic deformation behavior under uniaxial stretching. It was found that the crystalline chains of ULDPE show a bimodal molecular orientation parallel and perpendicular to the ...

Stiff‐ & hierarchical‐chain nature of atactic and stereoregular poly(substituted methylene)s

09-Jan-2018 | Kazuhiro Shikinaka, Kenta Suzuki, Hiroyasu Masunaga, Eiji Ihara, Kiyotaka Shigehara, Polymer International, 2018

ABSTRACT In this study, we estimated the chain nature of atactic and stereoregular poly(substituted methylene)s containing a phenylmethoxy side chain at each main‐chain backbone carbon atom using synchrotron X‐ray scattering to understand the topological and conformational properties of these ...

Impact of blend ratio on the properties of the graphene oxide filled carboxylated acrylonitrile‐butadiene rubber/styrene butadiene rubber blends

28-Dec-2017 | Xumin Zhang, Qing Yin, Xiaodong Xue, Hongbing Jia, Zhaodong Xu, Polymer International, 2017

Abstract Carboxylated acrylonitrile‐butadiene rubber (XNBR) and styrene butadiene rubber (SBR) composites with 3 phr (parts per hundred rubber) graphene oxide (GO) were prepared by latex mixing method. Effects of XNBR/SBR blend ratios on the mechanical properties, thermal conductivity, solvent ...

Fabrication of Sintered Porous Polymeric Materials: Effect of Chain Interdiffusion Time on Mechanical Properties

26-Dec-2017 | Meysam Salari, Gholamreza Pircheraghi, Polymer International, 2017

Abstract In this study, sintered porous polymeric materials made of High Density Polyethylene (HDPE), were fabricated through controlling chains interdiffusion time at the transition temperature of semicrystalline and melt states. At this intermediate state, where both crystalline and ...

The Role of a Secondary Process in Polymer Crystallization. 4. Polyethylene Revisited

23-Dec-2017 | James N. Hay, Polymer International, 2017

Abstract It is suggested that the overlap of primary and secondary crystallization is a cause of the repeated observation of non‐integer n values in polymer crystallization. The possibility that two concurrent crystallization processes occurring during the crystallization of polyethylene may ...
