Overview

Research shows formation of spherical silica particles in acidic sol-gel conditions, highlighting macromonomer's crucial role.

Key Points

  • Spherical silica microparticles were produced with precise control over size, influenced by stirring rate.
  • The introduction of zinc acetate enhanced particle strength through better silanol condensation.
  • Hydrophobic hybrid materials exhibited good thermal and oxidative stability, useful for various applications.
  • The method allows design adjustments based on macromonomer structure, pH, and stirring conditions.
