How to disperse Fe3O4 particles (size
There are several ways like using proper surfactant but below link might give some interesting information

You may be able to get it to disperse but, without agitation, the dispersed particles will quickly sediment due to their large size and density.
If your polymerization process is under stirred conditions, the particles may remain sufficient suspended.
Note that particles can be dispersed yet still sediment. My assumption is you mean dispersed such that they don't aggregate (?)
I am afraid your particles are too big to be dispersed. There should be some methods to synthesize Fe3O4 nanoparticles like hydrothermal...., if you can do that.
Use surfactants, or use ultrasound.
Is there any possibility to change internal structure of the polymer nano-composites after extruding the nano-composites via a melt extruder? Any reference will be appreciated. Thanks in advance.

Does light scattering occur more in less viscous solution than the highly viscous polymeric solution? Is there any such relationship or mathematical expression like this?

I personally feel this as a most confusing question. As per my understanding, if sample size is > 30, and sample is skewed, we can still use paramteric approach, as it will follow Z...
