The compatibilization of inorganic nanoparticles and organic polymers represents a challenge to be overcome in the development of polymeric nanocomposites. Typical development strategies involve the physical mixing of the species plus the use of a compatibilizing agent. The approach results in heterogeneous materials and complex mixtures.

In this context, the use of microwaves represents an important advantage. Microwaves interact specifically with the side chain of the polymeric species, which can act as a reactant in the in situ production of the inorganic nanoparticles. This process increases the compatibility of the species, improving homogeneity and reducing the compositional complexity of the final product
