Shaped artificial polymer articles with hybrid metal oxide particles

18-31. (canceled)

A composition comprising a polymer and hybrid metal oxide particles comprising:

• a continuous matrix of a first metal oxide having embedded therein an array of metal oxide particles, the metal oxide particles comprising a second metal oxide, wherein the hybrid metal oxide particles are substantially non-porous, wherein the hybrid metal oxide particles are present in an amount of 0.1 wt % to about 40 wt %.

34-48. (canceled)

A method of preparing a composition comprising a polymer and hybrid metal oxide particles, wherein the hybrid metal oxide particles are prepared by a method comprising:

• generating liquid droplets from a particle dispersion comprising a binder and metal oxide particles;
• and
• drying the liquid droplets to form hybrid metal oxide particles comprising a matrix of the binder and an array of the metal oxide particles embedded in the matrix, wherein the hybrid metal oxide particles are present in an amount of 0.1 wt % to about 40 wt %.
