Fabrication of a Metal Particle Array Based on a Self-Assembled Template from a Two-Armed Polymer
A two-armed polymer with a crown ether core self-assembles to produce macroporous films with pores perpendicularly reaching through the film down to the substrate. A possible assembling mechanism is discussed. The pore size can be conveniently adjusted by changing the solution concentration. These through-hole macroporous films provide a template for fabricating an array of Cu nanoparticle aggrega...

Ordered macroporous films from self-assembly of two-armed polymer with a crown ether core
Highly ordered honeycomb-like macroporous films were obtained via self-assembly of a two-armed polymer with a crown ether core under controlled conditions. A possible mechanism is speculated, primarily based on the strong affinity between the crown ether cores. The pore size and arrangement are sensitive to the solvent evaporation rate and the solution concentration. Upon spontaneous drying, the p...

Abstract
Both poly(L-lactide) (PLLA) and poly(ethylene succinate) (PES) are biodegradable semicrystalline polyesters. The disadvantages of poor
mechanical properties and slow crystallization rate of PLLA limit its wide application. Fully biodegradable polymer blends were prepared by blending PLLA with PES. Miscibility, crystallization behavior, and mechanical properties of PLLA/PES blends were i...

78. Nonisothermal crystallization behavior of a luminescent conjugated polymer... G.Z.Yang,X.L.Chen,Y.Xu,C.Z.Li,P.Y.Wu,T.X.Liu*. Polym. Int. 56(2),245-251, 2007.
The nonisothermal crystallization kinetics of poly(9,9-dihexylfluorene-alt-2,5-didodecyloxybenzene) (PF6OC12) from the melt were investigated using differential scanning calorimetry under different cooling rates. Several analysis methods were used to describe the nonisothermal crystallization behavior of PF6OC12. It was found that the modified Avrami method by Jeziorny was only valid for describin...

An amphiphilic diblock copolymer, poly(ethylene oxide)-block-poly(3-caprolactone) (PEO-b-PCL) was synthesized via the ring-opening polymerization of 3-caprolactone in the presence of a hydroxyl-terminated poly(ethylene oxide) monomethyl ether. The diblock copolymer was incorporated into epoxy thermosets. It is found that the formation of nanostructures of thermosetting blends is quite dependent on...

The origin of the low-energy emission of fluorene-based homo- and copolymers still remains controversial. In this work, the effect of thermal treatment on the emission properties of poly[(9,9-dihexylfluorene)-alt-co-(1,4-phenylene)] (PF6P) and its four derivatives modified by attaching different lengths of alkoxy side chains on the phenylene rings has been systematically investigated. By comparing...

66. The photophysical properties and morphology of fluorene-alt-benzene based conjugated polymer. G.Z.Yang, M.Wang, T.X.Liu*. Frontiers of Chemistry in China. 1(2), 130-137, 2006.
A series of fluorene-alt-benzene based conjugated main chain polymers chemically attached with alkyl side chains of different lengths on phenylene rings were designed and synthesized by a palladium catalyzed Suzuki coupling reaction. The UV-vis absorption and fluorescence spectra, thermal stability of spectral property, phase transition behavior and morphology of the synthesized polymers were inve...

Poly(vinylidene fluoride) (PVDF) and poly(3-hydroxybutyrate-co-hydroxyvalerate) (PHBV), both semicrystalline polymers, are miscible as shown by the single glass transition temperature over the entire composition range. Morphology of PVDF/PHBV blends was investigated by optical microscopy under two different crystallization conditions. PVDF showed the spherulitic morphology at 150 oC in the P...

Miscibility has been investigated in blends of poly(butylene succinate) (PBSU) and poly(vinyl phenol) (PVPh) by differential scanning calorimetry in this work. PBSU is miscible with PVPh as shown by the existence of single composition dependent glass transition temperature over the entire composition range. In addition, the polymer-polymer interaction parameter, obtained from the melting depressio...
