表面改質剤又は表面処理剤としての複合体コアセルベートコアミセル
Document Type and Number:
Japanese Patent JP2007506826
Kind Code:
A
Abstract:
The present invention relates to devices carrying on the surface polymeric micelles and a process for the preparation thereof. It further relates to the use of polymeric micelles as a surface coating for rendering a surface anti-fouling and/or protein-resistant. These polymeric micelles are of the so-called complex coacervate core type, exhibiting a hydrophilic, neutral corona and a core, which is formed by charge complexation of oppositely charged blocks. The polymeric micelle comprises a block polymer with an ionic block and a neutral and hydrophilic block, and at least a second polymer, either a block polymer or a homopolymer, with an ionic block that is oppositely charged to the first ionic block. All constituents exhibit excellent water solubility, and the micelles of the invention are therefore straightforwardly formed by mixing those different polymers together in aqueous conditions. Rather than a CMC these polymeric micelles have a preferred micellar composition (PMC), depending on the relative amounts of anionic and cationic groups. It is preferred to mix the components in such ratios that the total number of cationic polymeric groups over the total number of charged groups is in the range of 0.2 to 0.8. Complex coacervation and thus micellisation is entirely surpressed if the salt concentration reaches a critical value, which can be as high as 1 M. The coating composition according to the invention has the advantages that it can be applied to various types of surfaces and uses easy-to-synthesise hydrophilic components.
