Formation of normal and reverse bilayer structures by self-assembly of nonionic block copolymers bearing lipid-mimetic units

Article Abstract:

The static (SLS) and dynamic (DLS) light scattering as well as cryogenic transmission electron microscopy is used to investigate the self-assembly in aqueous (water) and non-aqueous (n-heptane) solutions of diblock and triblock copolymers of 1,3-didodecyloxy-2-glycidyl-glycerol (DDGG). It was seen that these copolymers had shorter poly(ethyleneglycol) (PEG) and larger poly(DDGG) moieties.

Mixed block copolymer aggregates with tunable temperature behavior

Article Abstract:

A block copolymer of propylene oxide (PO) and ethoxyethyl glycidyl ether (EEGE), (PO)2(EEGE)6(PO)2, was mixed at 1:0.1, 1:1 and 1:10 weight ratios with commercially available Pluronic (L64 or P85) block copolymers. The cooperative association of the copolymers in acqueous solution was studied by dynamic light scattering over a wide temperature range (5-60 degree centigrade).

Rheology of aqueous solutions of polyglycidol-based analogues to pluronic block copolymers

Article Abstract:

The aqueous solution properties of polyglycidol-based analogues are examined by rhealogy in relation to pluronic block polymers. Shear thinning is observed at concentrations above the critical micellization concentration. Zero shear viscosities are maximum at polyglycidol content of 50% wt, and decreased with increase in temperature.
