  • Remarks  Atlas Copco Sofie Deprez  "Smart materials is a very interesting concept. Are, at this moment, already applications which are also low cost - high number - easy producable- long life? (Not all this parameters must be present at the same time). Reputation of high cost is correct? What are the expectations for the future?  Flanders FOOD Steven Van CampenhoutMaterials/Materials Technology Center  "Use of smart materials for application in food industry: technological applications/opportunities (printable RFID, anti-microbial materials, applicability in food handling systems, other?) . Also keeping in mind food contact, cleanability, hygiene guidelines “  OCAS Arcelor Mittal Vincent Stone  Most self stratifying coatings systems described in the literature are solvent or water based. The heterophase polymer structure is obtained through phase separation of polymers dissolved in a common co solvent. We are facing the challenge to extend this self stratifying concept to systems (e.g. 100%, UV curable systems) that could further improve the economics and environmental performance of the coating process.  VITO Dirk Vangeneugden  I would like to evaluate to what extend the expertise within VITOs Materials Unit could contribute to the realization of some applications in the field of Smart Materials.  Mikrocentrum Jan van Moorsel  To find an easy way for solutions in nanomaterials and coatings for SMEs. 32 R.
