The combination of acrylic polymers and nano-particles into nanocomposites has attracted considerable attention in recent years, because these materials offer the prospect of new synergetic properties.
Recently, this kind of green material has been advocated for diversified applications, such as a potential nanofiller for the preparation of industrial composites[5，6].

For example, solid state reaction have limitations to its inherent disadvantages which are chemical inhomogeneity, high cost needed for raw materials and impurities that will introduced during the ball milling mixing [4].
The preparations of ZnAl2O4 and ZnFe2O4 using zinc nitrate hexahydrate, aluminum nitrate hexahydrate, iron nitrate hexahydrate and silicon dioxide as a starting materials.
This has been reported that when the metal oxide ion mixed with other material that has high energy bandgap will produced a new energy bandgap that will located between that semiconductor materials [16].

Different materials suit different properties; therefore, developers experiment with several materials for biomedical use.
These materials can be divided in four groups: (1) metals, (2) ceramics, (3) polymers and (4) composite materials.
Materials for direct methods include many metal alloys, alloy blends, ceramics, composite materials, and even rapid prototype plastics [9].
However, the molding of filled/porous samples or other materials (e.g.
