Random hydrophilic-hydrophobic copolymers
We study a single statistical amphiphilic copolymer chain AB in a selective solvent (e.g. water). Two situations are considered. In the annealed case, hydrophilic (A) and hydrophobic (B) monomers are at local chemical equilibrium and both the fraction of A monomers and their location along the chain can vary, whereas in the quenched case (which is relevant to proteins), the chemical sequence al...
متن کاملPolystyrene/wood composites and hydrophobic wood coatings from water-based hydrophilic-hydrophobic block copolymers
D. J. Gardner Department of Forest Management and Advanced Engineered Wood Composites Center, University of Maine, Orono, ME 04469, USA Abstract The combination of synthetic thermoplastic polymers and wood is normally problematic because wood surfaces are hydrophilic while typical thermoplastic polymers are hydrophobic. A possible solution is to use block copolymer coupling agents. In this work...
متن کاملHydrophobic-hydrophilic dichotomy of the butterfly proboscis.
Mouthparts of fluid-feeding insects have unique material properties with no human-engineered analogue: the feeding devices acquire sticky and viscous liquids while remaining clean. We discovered that the external surface of the butterfly proboscis has a sharp boundary separating a hydrophilic drinking region and a hydrophobic non-drinking region. The structural arrangement of the proboscis prov...
متن کاملFibronectin Adsorption on Hydrophilic and Hydrophobic Surfaces
Studies have been carried out on the adsorption properties of plasma fibronectin (FN) on hydrophobic and hydrophilic surfaces. The hydrophobic and hydrophilic surfaces used were nonwettable bacteriological dishes and wettable tissue culture dishes, respectively. At low plasma FN concentrations, there was more plasma FN binding to hydrophobic surfaces than to hydrophilic surfaces. Under these co...
متن کاملHydrophilic/hydrophobic nanostripes in lipopolymer monolayers.
The self-organization of macromolecules with a complex architecture is studied extensively in the last years, with the aim to nanostructure surfaces. Linear diblock copolymers with mutual antagonistic groups are a simple, much investigated system, since the respective block lengths determine the size of the nanostructure[1]. Yet little is known about the equilibrium structure when the forces fr...
