Abstract:
In contrast to nanoparticle powders, nanoparticles can be easily introduced into product formulations when provided as a Nanobatch: A nanoparticle dispersion that is compatible with the requirements of the respective formulations and downstream processes. Whereas nanoparticles carry a specific function, additional requirements in compatibility with the existing system translate into constraints in, e.g., viscosity, solid content, transparency, or surface roughness of a formulation, coating or bulk material. In the manufacturing process of real-world products, these compatibility requirements in, e.g., mixing, formulating, casting, coating, or molding make the whole dispersion process of nanoparticles the key element in nanoparticle processing. The Nanobatch-approach to introduce nanoparticles into product formulations comprises a dispersion process that includes the components of (i) functionalization of nanoparticles by surface modification as well as (ii) a customized procedure to disperse the modified particles into the formulation. We will present the example of dispersing pyrogenic SiO2 into an acrylic matrix following the nanobatch approach by (i) surface modification of the SiO2 nanoparticles with acrylic-groups and (ii) their introduction into acrylic-based formulations by the use of shear forces to give radiation curable nanoparticle composites. In addition, we discuss the scope of our approach.
