Tailoring nanoparticles for diverse applications: How to unfold the full potential of the nanoparticles in the final products?

摘要

Market experts estimate the potential of nanoparticles to be overwhelming. Demand for nanoparticles is projected to increase dramatically [1]. This view is understandable in the light of the possibilities nanoparticles offer to applications: For instance, nanosized ZnO particles, as well as nanosized TiO{sub}2 find use in coating formulations, as it improves scratch resistance as well as UV- blocking. In the end, one arrives at the conclusion that Nano-materials cannot be used directly into applications. According to a Frost and Sullivan-Report [2] there are several challenges to be overcome before nano-technology based solutions become viable. The real problem lies with the process of dispersion of these nano-materials into solvents. So, standard off-the-shelf products often won't work with formulations of the final product. It is the main goal of this article, to explain why standard off-the-shelf-products do not work, and also to introduce the solution, gained by tailoring nanoparticles to a given product formulation.
