The study of fibre/matrix bond strength in short hemp polypropylene composites from dynamic mechanical analysis
This paper presents results from an experimental study on the static and dynamic mechanical and viscoelastic properties of short hemp fibre polypropylene composites. Composites containing 10 to 60 wt.% short noil hemp fibre were injection moulded. The maleic anhydride grafted polypropylene (MAPP) and maleic anhydride grafted Poly(ethylene octane) (MAPOE) were used as coupling agents for modifying ...

Novel Alternating Polymer Adsorption/Surface Activation Self-assembled Film Based on Hydrogen Bond
By combining hydrogen bonding layer-by-layer self-assembly and the stepwise chemisorption method, a new alternating polymer adsorption/surface activation self-assembly method was developed. First a layer of diphenylarnine-4-diazonium-formaldehyde resin (diazo resin or DR) is deposited on a substrate. In the following surface activation step, the diazonium groups on the surface couple with re...

66. Sequence Distribution Effects on Glass Transition Temperatures of Copolymers: An Extended Gibbs-DiMarzio Equation in View of Bond Rotation Flexibility
In view of bond rotation flexibility and the additivity of stiff energy, a new equation containing mole fractions of sequences and glass transition temperatures (Tg's) of periodic copolymers was proposed. Meanwhile, the effect of stereochemical sequences was also taken into account. Even for the case of all substitutions on primary (C1), second (C2), and third (C3) carbon atoms adjoining ...

[Small] Fabrication of Patterned Polymer Brushes on Chemically Active Surfaces by in situ Hydrogen Bond Mediated Attachment of an Initiator
The cover picture shows a 3D AFM topographic image of PNIPAAM brushes micropatterned on a COOH-functionalized, polyacrylic acid (PAA) polymer brush substrate. In this novel patterning approach, the brush substrate is first patterned with an atom transfer radical polymerization (ATRP) initiator silane, which attaches by hydrogen bond formation to the COOH species at the top of the PAA brush subst...

[Macromolecules] PMHDO-g-PEG Double-Bond-Based Amphiphilic Graft Copolymer: Synthesis and Diverse Self-Assembled Nanostructures
Macromolecules 2009, 42, 4249–4256
ABSTRACT: Self-assembly behavior of a double-bond-based amphiphilic graft copolymer consisting of hydrophobic polyallene backbone and hydrophilic poly(ethylene glycol) side chains in tetrahydrofuran (THF)/water was investigated. Polyallene backbone was first prepared via living coordination polymerization of 6-methyl-1,2-heptadien- 4-ol (MHDO) init...

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. ...
