The use of engineered nanomaterials provides the potential to impart new and improved functionalities into coatings systems, polymer films, and adhesives. The impact and effectiveness of doped nanoparticulate additions into formulations is determined by many factors, including the composition, morphology, crystallinity, refractive index, and surface chemistry of the particles. Along with these particle characteristics, their degree of dispersion in the matrix or formulation is also a critical factor in obtaining enhanced functionality. Additionally, surface treatment and post-processing of the doped nanostructured particles allows for customization leading to compatibility with specific systems. With proper preparation and formulating, systems can be imparted with new benefits such as UV protection, IR filtering, conductivity, accelerated curing, and enhanced mechanical properties. The selection of nanomaterials to provide such features often coincides with a desire for transparency to visible light in the coatings and films, which requires careful engineering of both the particles and the formulations. Such transparent formulations often find their way into high value applications where several functionalities are combined, thereby enhancing the value proposition of the supplier to the potential customer. This presentation will cover synthesis of doped nanomaterials; properties and performance enhancements achieved through doping; customization for specific formulations; proper dispersion into matricies; and examples of applications for multi-functional nanostructured coatings, films, and adhesives.
