Direct covalent LBL assembly was performed on silica particles using PGMA and PAH as the building blocks. After core removal, hollow microcapsules with ultrathin shells and good shell completeness were obtained. The microcapsules have good mechanical strength and stability against extreme pHs and elevated temperature too.
