TL;DR: In this paper, non-covalent functionalization was used to functionalize graphene nanosheets (GNSs) through ππ stacking of pyrene molecules with a functional segmented polymer chain, which results in a remarkable improvement in the thermal conductivity of GNS-filled polymer composites.

TL;DR: A critical review of the melt phase synthesis of polyolefin graft copolymers with reactive functionality is given in this article, which may serve as precursors to other polyolefins with grafted maleic anhydride, fumarate and maleate esters.

TL;DR: In this article, the authors used mixed monolayers comprising of undecanethiol and ω-mercaptoundecyl bromoisobyrate (1) to initiate the controlled radical polymerization of methyl methacrylate (MMA) and glycidyl methacelate (GMA) from gold, and found that SAMs composed of 10% and 50% of initiator 1 grow PMMA brushes to approximately 1/10 and 1/2 the thickness of polymer brushes.
Abstract: We report the first systematic study of initiator density on surface-initiated polymerizations. We used mixed monolayers comprising of undecanethiol and ω-mercaptoundecyl bromoisobutyrate (1) to initiate the controlled radical polymerization of methyl methacrylate (MMA) and glycidyl methacrylate (GMA) from gold. We found that SAMs composed of 10% and 50% of initiator 1 grow PMMA brushes to approximately 1/10 and 1/2 the thickness of polymer brushes grafted from SAMs comprising 100% 1. We did not find a clear maximum initiator density, beyond which no further increase in polymer brush thickness is observed. We show that the initiator density at the start of the polymerization determines the ultimate “footprint” and hence density of polymer molecules in polymer brushes.

TL;DR: Glycidyl methacrylate derivatized dextran (dex-GMA) was synthesized by coupling of GMA to dextrans in the presence of 4-(N,N-dimethylamino)pyridine using DMSO as an aprotic solvent and characterized by GPC, FTIR, and NMR as discussed by the authors.
Abstract: Glycidyl methacrylate derivatized dextran (dex-GMA) was synthesized by coupling of GMA to dextran in the presence of 4-(N,N-dimethylamino)pyridine using DMSO as an aprotic solvent and characterized by GPC, FTIR, and NMR. The structure of the product was established with 1 H and CH-COSY NMR. The degree of substitution, as determined by NMR, can be controlled by varying the molar ratio of GMA and dextran. Almost quantitative incorporation of GMA (>90%) was established. Hydrogels were prepared by radical polymerization of aqueous solutions of dex-GMA, using ammonium peroxydisulfate (APS) and N,N,N',N'-tetramethylethylenediamine (TEMED) as the initiating system. The polymerization rate, as determined by FTIR analysis, was dependent on the APS, the TEMED, and the dex-GMA concentration. By proper selection of the polymerization conditions, hydrogels could be obtained in which more than 95% of the methacrylate groups had reacted within 20 min.

TL;DR: In this paper, a modified microfibrillated cellulose (MFC) was prepared by disintegration of bleached softwood sulphite pulp through mechanical homogenization, and the surface of the MFC was modified using different chemical treatments, using reactions both in aqueous and organic solvents.
Abstract: Microfibrillated cellulose (MFC) was prepared by disintegration of bleached softwood sulphite pulp through mechanical homogenization. The surface of the MFC was modified using different chemical treatments, using reactions both in aqueous- and organic solvents. The modified MFC was characterized with fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS) and transmission electron microscopy (TEM). Epoxy functionality was introduced onto the MFC surface by oxidation with cerium (IV) followed by grafting of glycidyl methacrylate. The length of the polymer chains could be varied by regulating the amount of glycidyl methacrylate added. Positive charge was introduced to the MFC surface through grafting of hexamethylene diisocyanate, followed by reaction with the amines. Succinic and maleic acid groups could be introduced directly onto the MFC surface as a monolayer by a reaction between the corresponding anhydrides and the surface hydroxyl groups of the MFC.
