Abstract
A nanocomposite includes at least one polymer and metal oxide nanoparticles dispersed in the at least one polymer. Each polymer can have a number average molecular weight of at least 10000 grams/mole. The at least one polymer includes a first polymer including (meth)acrylic acid monomer units. The metal oxide nanoparticles are surface modified with a carboxylic acid silane surface modifying agent. An aqueous dispersion that can be used to make the nanocomposite and a method of making the nanocomposite is described.
