The oldest and still intensely used biocidal materials release silver ions. Variations in the design of such materials is still the subject of the majority of publications on antimicrobial coatings. The designs cover sparingly soluble silver salts [87], silver nanoparticles [88], silver nanocomposites [89], and elemental silver coatings [32], The release of the silver ions and of other biocides is controlled by the encapsulating matrix, the solubility of the compound, and the material/medium equilibrium constant. 

The most common way to create an antimicrobial coating is still by impregnation with biocides such as silver compounds [90], furanones [91], iodine [92], triclosan...

Immobilization of NS-Ti02 on metallic materials such as stainless steel and aluminium plates opens up many new potential uses, because of their mechanical robustness, corrosion resistance, strength and shape-forming properties. These include architectural self-cleaning applications, antimicrobial coatings and many environmental applications including water and air purification [4, 5, 531] (see Tables 15-17). In this section, we describe the immobilization of NS-Ti02 on metallic materials as well as metal oxide substrates.

The use of polymeric ammonium salts and a sulfonic acid salt of sodium is an easy and efficient way of coating fabrics furthermore, employing the layer-by-layer (LbL) deposition technique can broaden the application of N-halamine biocides in other polar substances for use as antimicrobial coatings. Branched PEI, polypropylene (PP) and styrene maleic anhydride copolymers are a very good coating for food packaging materials, possibly due to the presence of both cationic- and N-halamine-forming structures. N-halamine cationic antimicrobial polymers based on (acrylamidopropyl)trimethylammonium chloride, PDDA chloride and poly(2-acrylamido-2-methylpropane sulfonic acid sodium salt) have been synthesised and coated onto cotton fabrics via an LbL deposition technique. 

Functionalised antimicrobial polymers can be developed by chain transfer (reversible addition-fragmentation transfer) polymerisation involving amino derivatives of methacrylate containing polydimethylsiloxane, which are further quarternised to yield new cationic polymers and are useful as antimicrobial coatings. 

The synthesis of functional polymers containing silver NP is environmentally friendly, experimentally simple and extremely quick. It opens up new possibilities for the development of antimicrobial coatings with medical and sanitation applications.
