26. Morphology and melting behavior of lamellar overgrowths after heat treatments of isotactic polystyrene. Liu TX, Lieberwirth I, Petermann J. MACROMOL. CHEM. PHYS. 202 (14): 2921-2925, 2001.
The morphology and melting behavior of overgrown lamellae (i.e. kebabs) in shish-kebab composite crystals for isothermally cold-crystallized isotactic polystyrene (iPS) have been studied using transmission electron microscopy (TEM). The bright- and dark-field morphological investigations indicate that the entire shish-kebab entity consists of at least three components: the central backbone (i.e,. ...

[2011][J. Mater. Chem., 2011,21: 6040-6045]Facile Synthesis of Organo–soluble Surface–grafted All–single–layer Graphene Oxide as Hole–injecting Buffer Material in Organic Light–emitting Diodes
Graphene oxide (GO) was modified by surface grafting and the product P-GO exhibited a surprisingly good solubility in common solvents(as high as 1.8 mg mL?1in DMF) without sonicationand can be spin coated to form large single-layer sheets on a substrate. In contrast to GO, all-single-layer P-GO sheets are readily formed in solution, which are highly useful for separation from other multi-layer s...

[Polym. Chem.] How does a tiny terminal alkynyl end group drive fully hydrophilic homopolymers to self-assemble into multicompartment vesicles and flower-like complex particles?
It is a theoretical and technical challenge to construct well-defined nanostructures such as vesicles from fully hydrophilic homopolymers in pure water. In this paper, we incorporate one terminal alkynyl group into a fully hydrophilic linear or non-linear homopolymer to drive its unusual self-assembly in aqueous solution to form multicompartment vesicles, spherical compound micell...

[Macromol. Chem. Phys.] Thermoresponsive Poly(2-oxazoline) Molecular Brushes by Living Ionic Polymerization: Kinetic Investigations of Pendant ChainGrafting and Cloud Point Modulation by Backbone and Side Chain Length Variation
Molecular brushes of poly(2-oxazoline)s were prepared by living anionic polymerization of 2-iso-propenyl-2-oxazoline to form the backbone and subsequent living cationic ring-opening polymerization of 2- n - or 2- iso -propyl-2-oxazoline for pendant chain grafting. In situ kinetic studies indicate that the initiation effi ciency and polymerization rates are independent from the number of initiato...

Poly(2,2,2-trifluoroethyl acrylate)-block-poly(ethylene oxide) (PTFEA-b-PEO) amphiphilic diblock copolymer was synthesized via the reversible addition-fragmentation transfer polymerization of 2,2,2-triffluroethyl acrylate with dithiobenzoyl-terminated poly(ethylene oxide) as a chain-transfer agent. The amphiphilic diblock copolymer was incorporated into epoxy resin to prepare the nanostructured ep...
