Abstract:
Various methods of treating surface-modified nanoparticles are described. Dual-ion exchange procedures (anion exchange and cation exchange), as well-as subsequent end-capping are described. Both ionically-bonded and covalently-bonded end-capping agents are discussed. The resulting low ion content, particularly low alkali metal and alkaline metal oxide ion content, treated, surface-modified nanoparticles, including such nanoparticles in a resin system, are also disclosed. Effects of low ion content on various properties of the resulting resin system, including blister-resistance, optical clarity, and rheology are included.
