Multi-metal phosphonates are generally provided. The multi-metal phosphonate can generally have the composition: AB(RPO), where A is Mg, Ca, Sr, Ba, Pb, La, or combinations thereof; B is Ti, Zr, Al, or combinations thereof; and R is an organic group (e.g., aryl group, an alkyl group, an alkenyl group, etc.). The multi-metal phosphonate can be combined with a polymeric material to form a polymeric film. Methods of making the multi-metal phosphonate by combining and reacting a metal oxide and an organophosphonic acid are also provided.

Methods of making layered mixed-metal phosphonates for high dielectric strength polymer nanocomposites

Mixed metal phosphonates are generally provided. The mixed metal phosphonate can generally have the composition: AB(RPO), where A is Mg, Ca, Sr, Ba, Pb, La, Co, Mn, Fe, or combinations thereof; B is Ti, Zr, Al, or combinations thereof; and R is an organic group (e.g., aryl group, an alkyl group, an alkenyl group, etc.). The mixed metal phosphonate can be combined with a polymeric material to form a polymeric film. Methods of making the mixed metal phosphonate by combining and reacting a metal oxide and an organophosphonic acid are also provided.
