What is it about?
Nanometer-sized oxide particles, added into polyester resins, can really improve its elastic modules and thermal resistivity if a loading level for the filling particles has been properly chosen. For example, the optimal mass-loading levels are equal approximately 0.5% and 1.5% for titanium (rutile) oxide and silica-titanium fumed oxide, respectively.

Why is it important?
Our findings show that loading-related behaviour of physical properties of the oxide-particle-filled resin-nanocomposites depends on particle’s size, their intrinsic properties, and a number of active surface sites of the particles.
Perspectives
Physical properties of the oxide-particle-filled resin-nanocomposites can be tailored by controlling either the loading level or chemical activity of particle’s surface, for example, by treating it thermally or functionalizing it.
