摘要：
A process for preparing microcapsules has an interconnected porous microsphere matrix The matrix includes at least one metal oxide and/or inorganic polymer. The microcapsules are obtained by a sol-gel process which involves preparing a first solution being a water-in-oil emulsion and adding to the emulsion a second acidic aqueous pre-hydrolyzed metal precursor solution and/or an organic polymer solution.
