Polymer nanocomposite implants with enhanced transparency and mechanical properties for administration within humans or animals

A nanocomposite for administration in a human or animal comprising:

• a polymer matrix;
• nanofillers comprising one or more elements selected from the group:
• barium, bismuth, cerium, dysprosium, europium, gadolinium, hafnium, indium, lanthanum, neodymium, niobium, praseodymium, strontium, tantalum, tin, tungsten, ytterbium, yttrium, zinc, and zirconium;
• a secondary species comprising metal oxide nanopowder additives;
• wherein the nanopowder additives comprise at least one element selected from the group consisting of:
• aluminum, calcium, gallium, iron, lithium, magnesium, silicon, sodium, strontium, titanium, carbon, oxygen and boron;
• wherein the nanofillers have a domain size less than 100 nanometers;
• and
• wherein the nanofillers are mixed into the polymer matrix at a loading of less than 95 volume percent to form a nanocomposite.
