If two nanofillers are given, let one be a nanosilica having surface area of 300 m2/g and other be a nanoclay having surface area of 100 m2/g. Then can we predict property of polymer matrix by their surface area.
What is the general Effect of surface area of nanofillers on the properties of polymer matrix nanocomposites...?
The properties of polymer matrix nano-composites may be different from their counterpart in terms of their application! So, it is a good idea to estimate the specific surface area of the composite itself.
The property profile depends upon how far and how well the filler particles bind interfacially with the polymer matrix. Although surface area is important surface chemistry and and surface topography too matters. So answer to which filler is better is governed by above factors as well as how much filler can be accommodated in polymer matrix depends upon polymer chemical structure and further it requires to optimize the concentration of filler for best properties to be imparted by the filler to the ultimate composite.
I recomended Dr.Kulkarni's idea in highly. We have to select the relevant test and collect the data from two composites. Then, we can compare their properties and find the better one. Nanofillers' dispersion with binding ability is highly required to fulfill your requirement.Surface area is a better factor to best dispersion of filler in the matrix. But, the thing is their attaching nature with the matrix. I have no idea about the shape of your two fillers. I think, One has spherical and other may be layer structure. It is also affect while accommodating fillers at the matrix.Refer more and collect the details.You can be functionalized your fillers to improve that binding ability with the matrix.
