General information
- Short Summary
- This project aims to develop an innovative eco-efficient environmental technology for inhibiting microbial induced corrosion (MIC), through the integration of microorganisms in a coating for metal surfaces of civil engineering structures.
- Full Description
- A more comprehensive approach to create antimicrobial coatings is by the use of natural biocides instead of metal ions. Lots of plant ingredients show at least bactericidal effects but some also show fungicidal effects (Sathianarayanan et al. 2010; Thilagavathi and Kannaian 2008; Rios and Recio 2005). Some fatty acids like lauric, myristic, palmitic, linoleic, and others exhibit antibacterial properties, which has been known for a long time (Kabara et al. 1972). Evening primrose oil and perilla oil can be coated by sol-gel technique to create antibacterial effects (Haufe et al. 2008) which can be deduced to the high content of linoleic acid in the oils. Essential oils and isolated compounds from these oils are also reported to be bactericidal. Eugenol, cinnamaldehyde, carvacrol, and thymol show antibacterial effects (Singh et al. 2002; Kollanoor et al. 2010; Awang et al. 2013; Yossa et al. 2014). A comprehensive overview of bactericidal effects of essential oils and components thereof is given by Inouye et al. They investigated 14 essential oils and 15 major ingredients on their bactericidal activity against six different bacteria. The most effective substances against E. coli and S. aureus are summarized in Table (Inouye et al. 2001). Sol-gel coatings offer the opportunity to incorporate such substances in a coating. However, some adversities should be mentioned. At first one should distinguish between pure substances and plant extracts. The latter consist apparently of a mixture of different substances. This can lead to a higher activity due to synergistic effects, but the content of active ingredients can spread over a broad range. Thus, a constant quality and high reproducibility of products endowed with these functions is difficult to achieve. Secondly, essential oils and other natural substances like pinene, limonene, menthol, and others exhibit a significant low vapor pressure. Temperatures above 120 0C are generally necessary to cure sol-gel films, so additives with low vapor pressures rapidly evaporate. It is still possible to obtain dry sol-gel coatings by applying lower temperatures, but usually these kinds of coatings are water soluble to some extent. It can be circumvented by lowering the curing temperature and prolonging the curing time (Boettcher et al. 1999); nevertheless, since the temperature dependency of the reaction speed and the vapor pressure are both exponential relations, positive effects are not estimated to be high.
- Advantages and Innovations
- Aircraft industry, in pipelines used in the oil and gas industry, in tanks used in the chemical industry, in fermentation units in the food industry, in cooling towers and their heat exchangers, in waste treatment plants, in the pharmaceutical and paper industry, in sewage main pipes and in cooling systems in the energy industry. The application of coatings onto metal surfaces can be used to prevent the formation of biofilms or to realize surfaces with low infection potential (Trapalis et al. 2003; Yu et al. 2003). By biocidal coatings onto metal surfaces besides the prevention of biofilm formation, additionally a reduction on metal corrosion can be reached. This prevention of biofilm formation is related to the material-protective application for the coated substrate.
