I have copper nanoclusters, can you provide me guidelines on how to find an appropriate polymer that can disperse it properly?
Small size of nanoparticle, low molecular mass & Tg of polymer matrix , common functionalities over both components and response towards the common solvents are the favorable situations to achieve the high dispersion of a nanoparticles into polymer matrix. Generally, inorganic nanoparticles are fairly dispersible into matrix of organic polymers at low concentrations (down to ppm). Carbonaceous nanoparticles are relatively better to disperse into organic polymers.Dispersion through direct reinforcement of nanoparticles into polymer matrix is relatively less effective rather than to conduct the polymerization reactions or reactive extrusion in presence of desired nanoparticles.@ King Chester Capinig Co
We have to optimize various polymer matrix to check better dispersibility below link will be helpful.

Hi
I do agree with M.G.H. Zaidi .
As M.G.H. Zaidi mentioned these properties are important before going for a application.
Moreover it is purely depend on purpose what Isam Alkhalifawi said.
if you tell the nature of outcome we can suggest you the correct one.

V R Arun Prakash we want to disperse them far enough from each other, and in an ordered pattern to minimize light scattering. We want to create a transparent thin film with the highest amount of copper nanoclusters inside.
Hi
King. Actually in all polymers the particles will agglomerate.we could not control them due to shrinking and hydrophobic nature of polymers. Better you do surface treat your particles and disperse in polymer. It will disperse as you need.
For the stabilize the nanoparticles polymer matrix encapsulation is a good approach. In my experience polymethyl methacrylate (PMMA) is the best polymer for perovskite QDs. So you can try your QDs with PMMA. For more details you can follow below link;

Good Luck.
Thank you Rajan Kumar Singh. I am actually looking for guidelines/things that to consider to be able to find an appropriate matrix for my nanoparticle. It is just now that I realize I am not confined to polymers. I now have an option to look for other materials that can provide structure and dispersion (i.e. matrix like silica through sol-gel method).
But V R Arun Prakash answer is good for me. Passivate your particle to reduce attractive force between them. We use GSH to reduce aggregation of copper nanoclusters.
If you are planning to use thermosets use amino silanes like APTMS, APTES etc... If you use thermoplastics any capping agent you can use.
