Silane coupling agents such as gamma-methacryloxypropyl trimethoxysilane have also been tried, by grafting them onto nanosilica particles. Compatibilisation can sometimes be further enhanced by functionalising the polymer as well, e.g., polypropylene may have to be treated with maleic anhydride in order to insert it between the layer planes of the clay.

Silica surface modification using silane coupling agents (e.g. 3-aminopropyl-trimethoxysilane (APTS), aminopropylmethyldiethoxysilane (APMDS) or methacryloxypropyltriethoxysilane (MPTS) can be carried out in aqueous or non-aqueous solution systems, but for large scale production, an aqueous system is preferred [21, 22]. 

Zhao et al. [32] carried out a surface modification of Ti02 nanoparticles with the silane coupling agents 3-aminopropyl trimethoxysilane (APTMS) and 3-Isocyanato propyl trimethoxysilane (IPTMS). The process of nanoparticle surface modification by silane coupling agents is shown in Fig. 2. Various anionic surfactants have been used to disperse nano Ti02 [33],...
