【Applied Physics A-Materials Science & Processing】Enhanced microwave absorption performance of polyaniline-coated CNT hybrids by plasma-induced graft polymerization
Highly conducting CNT/polyaniline hybrids were prepared by plasma-induced graft polymerization, i.e., plasma pretreatment of CNTs and further in situ polymerization of aniline. Plasma pretreatment made more aniline grafted on the CNTs’ surface by the role of oxygen radicals. SEM images showed that the surfaces of CNTs were uniformly coated by PANI. FTIR showed that there was presence of strong ...

【22 Journal of Applied Polymer Science】 Relationship between branch length and the compatibilizing effect of polypropylene-g-polystyrene graft polymer on polypropylene/polystyrene blends
Three polypropylene‐g‐polystyrene (PP‐g‐PS) graft copolymers with the same branch density but different branch lengths were evaluated as compatibilizing agents for PP/PS blends. The morphological and rheological results revealed that the addition of PP‐g‐PS graft copolymers significantly reduced the PS particle size and enhanced the interfacial adhesion between PP and PS phases. Furthermore,...

【07 Polymer】 Synthesis and structure-property relationships of polypropylene-g-polystyrene and polypropylene-g-poly(n-butyl acrylate) graft copolymers with well-defined molecular structures
Several polypropylene-g-polystyrene (PP-g-PS) and polypropylene-g-poly(n-butyl acrylate) (PP-g-PnBA) graft copolymers with well-defined molecular structures, basing on the same PP-Br precursor, were synthesized via a combination of metallocene-catalyzed polymerization and ATRP. The structure-property relationships of the resultant graft copolymers were systematically investigated. The crystallizat...

Dynamic Origin and Thermally Induced Evolution of New Self-Assembled Aggregates from an Amphiphilic Comb-Like Graft Copolymer: A Multiscale and Multimorphological Procedure
Considering the shape plays a crucial role in determining physical and chemical properties of aggregates,[13] the controlled fabrication and switch of morphologies have been paid a great attention, which has been implemented by regulating the conditions, such as solvent,[14] pH,[15] redox,[16] and so on. Typically, crystallization is an important factor utilized to ...

45. [J. Colloid Inter. Sci.] Core cross-linked poly(ethylene glycol)-graft-Dextran nanoparticles for reduction and pH dual responsive intracellular drug delivery
A kind of core cross-linked poly(ethylene glycol)-graft-Dextran nanoparticles (CPD NPs) was prepared by a simple chemical cross-linking method for reduction and pH dual response drug delivery. The resultant CPD NPs are of homogeneous spherical structure with sizes from 69 ± 11 to 107 ± 18 nm. Doxorubicin (DOX) was then loaded into the CPD NPs in high efficiency, and showing typical redu...

【Applied Surface Science】Surface modification of poly(styrene-b-(ethylene- co-butylene)-b-styrene) elastomer via photo-initiated graft polymerization of poly(ethylene glycol)
Abstract:
Poly(styrene-b-(ethylene-co-butylene)-b-styrene) (SEBS) copolymer biomedical elastomer was covalently grafted with poly(ethylene glycol) methyl ether methacrylate (PEGMA) via a photo-initiated graft polymerization technique. The surface graft polymerization of SEBS with PEGMA was verified by ATR–FTIR and XPS. Effect of graft polymerization parameters, i.e., monomer concentration, U...
