I would like to determine the mechanical and thermal properties of polymer nanocomposites. Suggest to me, which method is best for the preparation of polymer nanocomposites.
Best method for preparation : depends upon nature of your polymer
Thermal Properties : DSC and TGA
Mechanical properties : Rheometer (for hydrogel/resin) and Dynamic mechanical analyser (for solids)
For bulk production of polymer nanocomposites by using melt blending method
the best preparation technique depends on the required properties. However, in all cases you need to assure a good dispersion of the nanoparticles, this can be done by a particles treatment followed by dissolving your matrix in the appropriate solvent then adding the treated particles, and finally use ultrasound to further disperse your particles in the matrix. remove the solvent and cure your nanocomposites.
Depends upon nature of your polymer (thermoplastic, thermoset, chain length, hydrophobic, hydrophilic etc), and nature of nano-reinforcement. Make sure they are compatible.
For dispersion, you can use different approaches such as mechanical, chemical, physical. In all cases you need to assure a good dispersion, distribution of the nano-reinforcement at close to nano level in the polymer.
Attached are couple articles for your references.
