PolyamidesUn polyamide est un polymère contenant des fonctions amides -C(=O)-NH- résultant d'une réaction de polycondensation entre les fonctions acide carboxylique et amine.
Selon la composition de leur chaîne squelettique, les polyamides sont classés en aliphatiques, semi-aromatiques et aromatiques. Selon le type d'unités répétitives, les polyamides peuvent être des homopolymères ou des copolymères.

| Résumé : |
Nanocomposite coatings can reduce infection within a medical environment.
Coatings which are able to reduce the risk of biofilm formation on material surfaces are relevant for medical devices in order to reduce infections but also important for other technical and consumer applications. Either by binding biocides in the surface or by incorporating such substances into the coating, the proliferation of bacteria and fungi in the material can be reduce significantly.
Silver is especially suited as an antimicrobial substance due to its high antimicrobial efficacy accompanied with a low or non-existent cytotoxicity.
In the first part of this paper the use of nanoparticulate metallic silver particles as an antimicrobial agent in polyurethane coatings is presented. In the second part a new coating system, which combines highly efficient nanoparticulate silver particles with the versatile plasmapolymer coating technology is discussed. In-vitro tests show an excellent antimicrobial effect of the silver particles against a variety of clinical relevant bacteria (including multiresistant strains of MRSA and MRSE).
Additionally the surface energy of the plama polymer can be varied in order to change the adhesion properties of bacteria. |
