Such scaffolds exhibited compressive strengths on the same order of magnitude as cancellous bone (10–1000 MPa) ( Hollister, 2005).
The compressive strength of the scaffold was found to be proportional to its HA content. After the mixture is emulsified, it is cast into molds and vacuum dried to yield a porous PLGA/HA composite foam. One technique uses an emulsion of PLGA and HA dissolved in chloroform with an aqueous PVA solution ( Devin et al., 1996). More recent methods incorporate microparticles of HA, rather than fibers, into the scaffold network. This study aims to investigate the feasibility of preparing polymer nanocomposites with different types of polymer matrices and fillers with various technique approaches. It would be attractive to prepare polymer nanocomposites via different techniques using silica/fumed silica and nanoclay as fillers to improve the properties of the conventional polymer nanocomposites.
Solution-intercalation film-casting method was applied to fabricate biodegradable poly( d, l-lactic acid)-layered silicate nanocomposites that improved the thermal stability of the nanocomposites ( Stathokopoulou & Tarantili, 2014). (2011), PVA-bentonite nanocomposites was well dispersed by a solvent casting technique, which improved the mechanical, thermal and water barrier properties. PVA-silica organic-inorganic membrane was prepared using functionalized mercapto and amine groups by solution casting method for adsorption of Cu(II) ions from aqueous solutions ( Keshtkar et al., 2013).
