What are the Challenges in Achieving Better Dispersion?
Several factors can hinder the dispersion of nanoparticles:
Surface Chemistry: Nanoparticles often have high surface energy, making them prone to agglomeration. Solvent Compatibility: The solvent used must be compatible with both the nanoparticles and the matrix to ensure uniform dispersion. Stabilization: Stabilizing agents or surfactants may be necessary to prevent nanoparticles from clumping together. Mechanical Forces: Insufficient mechanical mixing can result in poor dispersion.
