Single-Chain Mechanics of Poly(N,N-diethylacrylamide) and Poly(N-isopropylacrylamide): Comparative Study Reveals the Effect of Hydrogen Bond Donors
关键字：Poly(N,N-diethylacrylamide), Poly(N-isopropylacrylamide)
The
single-chain mechanics of two similar thermosensitive polymers, poly(N,N-diethyl-acrylamide) (PDEAM) and poly(N-isopropyl-acrylamide) (PNIPAM), have been studied by atomic
force microscopy-based single-molecule
force spectroscopy (SMFS). In a typical nonpolar organic
solvent, octane, both the two polymers show the same
inherent elasticity, although they have different substitutional groups. ...

Super tough biobased poly(ethylene 2,5-furandicarboxylate) materials: synthesis and thermo-mechanical properties of poly(ethylene 2,5-furandicarboxylate-mb-poly(tetramethylene glycol)) multiblock copolymers.
Poly(ethylene 2,5-furandicarboxylate) (PEF) is a biobased polyester with superior thermo-mechanical and gas barrier properties than poly(ethylene terephthalate) (PET), the most widely used petroleum-based polyester. However, PEF is more brittle than PET. To toughen PEF, a series of P(EF-mb-PTMG) (PETF) multiblock copolymers with high intrinsic viscosity were successfully synthesized via melt pol...

In vitro degradation of biodegradable blending materials based on poly(p-dioxanone) and poly(vinyl alcohol)-graft-poly(p-dioxanone) with high molecular weights
Amphiphilic biodegradable graft copolymer, poly(vinyl alcohol)-graft-poly(p-dioxanone) (PVA-g-PPDO), was used to prepare a new biodegradable material by blending with poly(p-dioxanone) (PPDO). The in vitro degradation properties of the copolymer and blends with different contents of PVA-g-PPDO were studied in phosphate buffer at 37 degrees C. The degradation processes of the PVA-g-PPDO and its ble...
