Title : Organofunctional silicon compounds – synthesis and application as anti-biocorrosion coating
Abstract:
Biological corrosion is the term referring to undesirable deposition and growth of all kinds of microorganisms, mainly fungi, bacteria and algae. It is a multistage and complex process leading to destruction of materials on which this deposition and growth, in the form of a biofilm, took place. The phenomenon leads not only to technological problems but can have harmful effects on human health. Most often this phenomenon is discussed in the context of construction materials such as bricks, concrete, roof tiles, glass and wood.
Production of advanced materials contributes to driving social and economic development, which in turn demands new materials of target properties to meet specific needs. New materials of strictly defined structure and properties are designed on the basis of results of fundamental studies.
Recently, the group of materials showing amphiphilic properties has become of increasing interest in the global search for materials of specific properties [1-2]. Compounds with amphiphilic properties are very dynamically developing, multifunctional, because they are a compilation of chemical, biological and physical research. There is a wide range of applications of this group of which will reduce the surface tension. The amphiphilic character of the compound devised will be achieved by the introduction of polyether compounds that easily make hydrogen bonds with the water molecules in the solution thanks to the presence of oxygen in the ethylene bridges. It should be mentioned that the choice of siloxane as the core of the molecule has not been accidental. It shows some very important properties such as high thermal, chemical and antioxidative resistance and water vapor permeability. The innovative approach to the problem is the use of functionalized organosilicon compounds showing amphiphilic properties as the modifiers of the materials surfaces to be protected. The coatings based on functionalized organosilicon compounds and protecting against biological corrosion may be used for all kinds of supporting materials. For example they can be used for protection of glass against the effect of the elements. In this presentation the selected surface properties were presented too.
Design and production of coatings protecting against biofilm formation and negative effects of biological corrosion, is a top challenge of the current world material technology.
