Patent ID: 11959921

Abstract:
A method for forming dendritic mesoporous nanoparticles comprising preparing a mixture containing one or more polymer precursors, a silica precursor, and a compound that reacts with silica and reacts with the polymer or oligomer formed from the one or more polymer precursors, and stirring the mixture whereby nanoparticles are formed, and subsequently treating the nanoparticles to form dendritic mesoporous silica nanoparticles or dendritic mesoporous carbon nanoparticles. The silica precursor may comprise tetraethyl orthosilicate (TEOS), the one or more polymer precursors may comprise 3-aminophenol and formaldehyde and the compound may be ethylene diamine (EDA). There is a window of amount of EDA present that will result in asymmetric particles being formed. If a greater amount of EDA is present, symmetrical particles will be formed.
