Enhanced Exfoliation of Organoclay in Partially End-Functionalized Non-Polar Polymer
We found that enhanced exfoliation of clay up to 20 wt% in non-polar polybutadiene (PB) if the PB was blended with a relatively small fraction of hydroxyl–terminated polybutadiene (HTPB). The choice of an intermediate polymer composition to enhance exfoliation was motivated by theoretical predictions of end-functionalizing effects of Balazs, Farmer, and coworkers. A combin...

Polymer 2007: Synthesis and degradation of poly(beta-aminoester) with pendant primary amine
Three poly(beta-aminoester)s with pendant primary amines were synthesized by Michael addition of N-Boc-protected diamine to 1,4-butanediol diacrylate, followed by removal of N-Boc-protective group under anhydrous acidic conditions. The degradation rate of poly(beta-aminoester)s with pendant primary amines is dependant on their side-chain structures and pH value of incubation buffer. The degradatio...

Surface-induced phase separation of binary polymer blends on the chemically patterned substrate
The patterned substrate with alternating SiO2 and octadecyltrichlorosilane (OTS) self-assembled monolayers (SAM) was used to induce phase separation of PS (polystyrene) and PVP (poly2-vinylpyridine) binary polymer blend films. The PS- and PVP- phase were situated on the OTS and SiO2 domains, respectively. It revealed that even though the characteristic length scales (D) of phase separation were di...

How to form regular polymer microstructures by surface-pattern-directed dewetting
The substrates with regular patterns of self-assembly monolayers (SAMs) produced by microcontact printing with octadecyltrichlorosilane (OTS) was employed to direct thin polystyrene dewetting to fabricate ordered micrometer scale pattern. The pattern sizes and pattern fashion can be manipulated by controlling the experimental parameters. The pattern formation mechanisms have been discussed. The de...

Experimental phase diagram of a model colloid-polymer mixture in the protein limit
Sterically stabilized silica nanoparticles were synthesized, and turbidity measurements confirmed that they behaved as hard spheres in cyclohexane. Poly(isoprene) was added to give mixtures in the protein limit with a polymer coil/colloid radius ratio of 4.8. Their phase behavior under good solvent conditions was studied experimentally. The critical colloid volume fraction was φ = 0.13, wherea...

Tunable emission from composite polymer nanoparticles based on resonance energy transfer
We have fabricated semiconducting polymer nanoparticles from poly[2-methoxy-5-(2'-ethyl-hexyloxy)-p-phenylene vinylene] (MEH-PPV), poly(N-vinylcarbazole) (PVK), and their blends via a reprecipitation method. When excited by the peak wavelength of the PVK absorption band, the polymer nanoparticles show enhanced emission from the MEH-PPV component. The emission color can be tuned from blue to orange...
