Area of Science:

  • Materials Science
  • Nanotechnology
  • Colloid Chemistry

Background:

  • Polymer latex particles require surface modification for advanced applications.
  • Developing efficient silica coating methods is crucial for particle functionalization.
  • Stöber silica deposition offers a versatile route for inorganic shell formation.

Purpose of the Study:

  • To develop an efficient method for silica coating of micrometer-sized poly(methyl methacrylate) latex particles.
  • To investigate the role of chitosan in the silica deposition process.
  • To control and tune the silica shell thickness.

Main Methods:

  • Utilized the Stöber protocol with tetraethyl orthosilicate (TEOS) for silica deposition.
  • Employed chitosan adsorption onto latex particles prior to silica coating.
  • Applied thermogravimetry, scanning electron microscopy (SEM), aqueous electrophoresis, and X-ray photoelectron spectroscopy (XPS) for characterization.

Main Results:

  • Chitosan pre-treatment significantly improved silica shell formation, preventing secondary nucleation.
  • Silica shells with tunable thickness (45-144 nm) were successfully prepared.
  • Calcination revealed hollow silica particles with smooth shells, confirmed by SEM.
  • Characterization techniques validated uniform silica overlayers on the latex particles.

Conclusions:

  • Chitosan acts as a surface modifier, promoting uniform silica deposition rather than catalyzing silica formation.
  • The developed method is a generic and efficient strategy for coating micrometer-sized particles at high solids.
  • The resulting hollow silica particles hold potential for diverse material applications.
