Claims31
An apparatus for absorbing ultraviolet, visible and near-infrared radiation emitted from natural or artificial sources, comprising:
- a transparent solid material formed by the polymerization of a monomer;
- melanin;
- and
- a reagent being chemically attached to the melanin through a covalent bond to make the melanin derivatized melanin so that the melanin is more soluble in the monomer prior to the polymerization of the monomer, the derivatized melanin being connected to the material.
An apparatus for absorbing ultraviolet, visible, and near-infrared radiation emitted from natural or artificial sources, comprising:
- a transparent polymeric solid material being formed by the polymerization of a monomer;
- and
- a sequestered melanin being connected with the material, the melanin being sequestered by the monomer through a covalent bond between the melanin and the monomer to prevent the interference of the melanin with the polymerization of the monomer.
A product prepared by a process comprising the steps of:
- mixing melanin with a monomer;
- sequestering the melanin by forming a covalent bond between the melanin and the monomer;
- and
- polymerizing the monomer;
- the formation of the covalent bond preventing the interference of melanin with the polymerization of the monomer.
A product prepared by a process comprising the steps of:
- reacting melanin with a reagent to from derivatized melanin wherein a covalent bond is formed between the reagent and the melanin;
- mixing the derivatized melanin with a monomer;
- and
- polymerizing the monomer.
An apparatus for absorbing ultraviolet, visible and near-infrared radiation emitted from natural or artificial sources, comprising:
- a transparent solid material formed by the polymerization of a monomer;
- melanin;
- and
- a reagent which physically traps the melanin to make the melanin sequestered melanin so that the melanin is more soluble in the monomer prior to the polymerization of the monomer, the sequestered melanin being connected to the material.
A product prepared by a process, comprising the steps of:
- mixing melanin with an agent to physically trap the melanin to physically sequester the melanin;
- combining the physically sequestered melanin with a monomer;
- and
- polymerizing the monomer.
