Yes, It is necessary to compare the adsorption charactersitics of nanocomposite with its individual nanoparticles. So that you can find the speciality of the nanocomposite.

I would consider testing the absorption characteristics of the whole composite first. After testing the whole composite I would consider testing the materials that comprise it individually. This is how I would approach testing a composite: the entire composite is the first most important thing to test first, then the materials that comprise the composite. I am sure that this is not the only way to go about testing a composite.

Thank you so much for taking time in helping me out

I would add to the above answers that in general its always informative to test properties , if possible, of all individual components and a nanocomposite to find a specificity of the latter and to understand and evaluate a possible synergism.

Yes , I think it is necessary because the nanocomposite should have the same properties of its components, otherwise it will be nanohybrid.

Not the same. The nanocomposite properties typically are not equal to the arithmetic sum of the components properties. Even more - the properties nanocomposite often are synergetic. However, if you find the same properties you then have not the nanocomposite but a mechanical mixture of the components.

Even mechanical mixtures of components can have wildly different strengths, properties, and work of fracture than their individual components. In example Fiberglass resin composites can have a work of fracture that far exceeds the sum of their components. Some of the material's properties may be related to the material's structure.
