Conformation of a Diblock or Random Square-Well Copolymer in Dilute Solution

Combined with an approximation suggested by Taylor and Lipson for the third-order correlation function and the translational invariance approximation, the BGY equation is used to calculate the conformation and thermodynamic properties of a diblock square-well copolymer or a random square-well copolymer. The BGY results for the end-to-end distribution of copolymers are in good agreement with Mon...

Pathway to copolymer collapse in dilute solution: uniform versus random distribution of comonomers.

Monte Carlo simulations show that copolymers with uniformly (or periodically) distributed sticky comonomers collapse "cooperatively," abruptly forming a compact intermediate comprising a monomer shell surrounding a core of the aggregated comonomers. In comparison, random copolymers collapse through a relatively less-compact intermediate comprising a comonomer core surrounded by a fluffy monomer...

Amphiphilic Diblock Copolymer Surface

10 11 Both visible and infrared (IR) spectroscopic ellipsometry have been employed to study the 12 structure of thin layers of bovine submaxillary mucin (BSM) adsorbed on poly(acrylic acid13 block-methyl methacrylate) (PAA-b-PMMA) copolymer and poly(methyl methacrylate) 14 surfaces at three pH values (3, 7 and 10). The adsorbed mucin layer on the copolymer surface 15 had the greatest thickness ...

Coarsening and Self-organization in Dilute Diblock Copolymer Melts and Mixtures

This paper explores the evolution of a sharp interface model for phase separation of copolymers in the limit of low volume fraction. Particles both exchange material as in usual Ostwald ripening, and migrate because of an effectively repulsive nonlocal energetic term. Coarsening via mass diffusion only occurs while particle radii are small, and they eventually approach a finite equilibrium size...

Hollow flower micelles from a diblock copolymer.

A poly(2-vinylpyridine)-block-poly(2-(4-vinylphenyl)pyridine) (P2VP106-b-PVPPy95) coil-coil diblock copolymer forms hollow flower micelles in a mixed solvent of methanol and water (95/5, v/v) in a one step process. The geometry and composition of the micelles allow formation of a Pt-Au bimetallic dendritic nanocatalyst with a Pt leaf at room temperature.
