- Theoretical description of unconstrained thermally induced shape-memory recovery in crosslinked polyethylenes
Igor Kolesov, Oleksandr Dolynchuk and Hans-Joachim Radusch
Article first published online: 21 APR 2014 | DOI: 10.1002/polb.23491
To date, there has been no physically grounded theory to describe shape-memory (SM) behavior of crosslinked semicrystalline polymers. Here, based on the modified Eyring-Halsey model, a novel theoretical approach accounting for the influence of the crystallizable polymer network and of entangled slipped molecular chains was developed to describe thermally induced recovery of pre-deformed and crystallized crosslinked polymers. Modeling of SM recovery strain and rate was successfully performed for three types of polyethylene with different crystallinity and crosslink density.

Marcos Mariano, Nadia El Kissi and Alain Dufresne
Article first published online: 19 APR 2014 | DOI: 10.1002/polb.23490
Impressive mechanical properties and reinforcing capability, abundance, low weight, renewability, and biodegradability make cellulose nanocrystals ideal candidates for use in polymer nanocomposites. This Review also looks at the broad range of potential applications of these nanoparticles, as well as the remaining questions in the field.
- Formation of a polycrystalline film of donor material on PEDOT:PSS buffer induced by crystal nucleation
Koji Harano, Satoshi Okada, Shunsuke Furukawa, Hideyuki Tanaka and Eiichi Nakamura
Article first published online: 19 APR 2014 | DOI: 10.1002/polb.23493
Poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) is a transparent, conductive polymer used in multiple electronic applications. The polymer induces crystal nucleation of organic donor molecules at their interfaces. Scanning electron microscopic analysis reveals that polycrystalline films of tetrabenzoporphyrin and poly(3-hexylthiophene) form on the thin film of PEDOT:PSS, while nucleation scarcely occurs on graphitic surfaces. The acidic PEDOT:PSS surface traps the donor molecules, which acts as a template for heterogeneous nucleation.
- Enhancing the PLA crystallization rate by incorporating a polystyrene-block-poly(methyl methacrylate) block copolymer: Synergy of polystyrene and poly(methyl methacrylate) segments
Chien-Pang Wu, Cheng-Chien Wang and Chuh-Yung Chen
Article first published online: 19 APR 2014 | DOI: 10.1002/polb.23492
Polylactide (PLA) is a highly biodegradable bioplastic that is synthesizable from renewable resources and has received great interest, but its slow crystallization rate can impede its wider application. Here, polystyrene-block-poly(methyl methacrylate) (PS-b-PMMA) was added to PLA to investigate its effects on crystallization behavior. The synergistic effects of the PS and PMMA blocks were only achieved when they were both present in the PLA matrix, and PS-b-PMMA was found to be an effective nucleating agent for PLA.
- Superhydrophobic surfaces with low and high adhesion made from mixed (hydrocarbon and fluorocarbon) 3,4-propylenedioxythiophene monomers (pages 782–788)

Article first published online: 17 APR 2014 | DOI: 10.1002/polb.23483
Superhydrophobic surfaces with high and low adhesion are obtained by electropolymerization 3,4-propylenedioxythiophene derivatives containing both a hydrophobic chain and a short fluorocarbon chain. The aim of this work is to replace the use of long fluorocarbon chains, which have bioaccumulative potential in animal and human bodies, while keeping relatively high oleophobic properties.
