Chemically active functional coating

Functional coatings perform by means of physical, mechanical, thermal and chemical properties. Chemically active functional coatings perform their activities either at film-substrate interfaces (anticorrosive coatings), in the bulk of the film (fire-retardant or intumescent coatings), or at air-fihn interfaces (antibacterial, self-cleaning) [16]. 

Of particular interest are the specific chemical interactions that occur between the coupling agent s active functionality and either the metal oxide or the polymeric top-coat. Recently, reflection angle infrared spectroscopy (RAIRS) [12, 13] and... 

Cell adhesion on a nonfunctional scaffold is mediated dominantly by nonspecific, entropically favored adsorption of a layer of cell adhesion proteins, excreted by the cell itself [61]. In order to obtain and retain the native function of these proteins, attempts are being made to tune the hydrophilicity or hydrophobicity of the scaffold surfaces [62], Different methods of surface activation are commonly applied, e.g., blending, copolymerization, plasma treatment, etching, radiation, chemical surface modification, coatings, and combinations of those. 

This chapter presents an overview of the synthesis, ensemble photoluminescence properties and blinking of single CdSe quantum dots. The stress is on (i) widely accepted methods of synthesis, (ii) the origin of photoluminescence and variations of photoluminescence as functions of surface-coating, surface-passivating molecules, chemical environment, and thermal- and photo-activations, and (iii) photolumines-...
