Public ISBD [article]  inMaterials and corrosion > Vol. 61 N° 12 (Décembre 2010) . - pp. 986–992 Titre : Biodeterioration of synthetic materials – A brief review Type de document : texte imprimé Auteurs : H.-C. Flemming, Auteur Année de publication : 2011 Article en page(s) : pp. 986–992 Note générale : Génie mécanique Langues : Anglais (eng) Mots-clés : Biodeterioration  biofilms  plastics Résumé : Although synthetic polymers are part of our global waste problem because they are not sufficiently biologically degraded, microorganisms can severely impair the properties and functions of these materials. It seems as if consumers do not really acknowledge this cause of problems and there is only sparse systematic research about. Damaging mechanisms include (i) covering of surfaces (biofouling) which may be enhanced by leaching of biodegradable additives, (ii) depletion of such additives which can lead to loss of material properties, (iii) intrusion into materials by fungal hyphae, (iv) water uptake, and (v) discoloration. The common countermeasure is the addition of biocides or simply to tolerate the effects of biodeterioration and live on with them. It is suggested to encourage further systematic research, and to develop integrated strategies in order to avoid problems, e.g., based on nutrient and water limitation whenever possible.
