The triple‐helix structure of grafted collagen is reinforced with bimetallic Al 2 O 3 –ZrO 2 nanoparticles (see figure), thereby significantly improving the mechanical and thermal stability of the polymer matrix. The stability of this hybrid nanocomposite is thought to derive from the chemical bonding between the surface oxygen atoms on the nanoparticles and functional groups on the collagen matrix. The improved and robust collagen bioscaffolds may potentially be useful for bionic and biomedical applications.
