Novel procedure for polymer coatings of nanoscopic surface topology

Surface Coatings International Part B: Coatings Transactions

Summary

A new coating technique based on the so-called lower critical solution temperature (LCST) phase transition phenomena known from polymer solutions has been studied. Contrary to the commonly-known features that precipitation from solution occurs upon cooling (or solvent evaporation) or by a precipitant, LCST behaviour means a coagulation and precipitation of the polymer from solution upon heating, once a critical temperature is exceeded. This technology not only allows a controlled surface modification of pigments or flat substrates by an organic polymer coating layer, but also allows one to introduce specific surface features of nanoscopic to mesoscopic dimensions. The surface topology may be reversibly varied from a regular, almost close-packed, mesoscopic hemisphere texture to a nanoscopic roughness or rendered evenly smooth.
