    Abstract: A process and apparatus for producing a nanovoided article, a nanovoided coating, and a low refractive index coating is described. The process includes providing a first solution of a polymerizable material in a solvent; at least partially polymerizing the polymerizable material to form a composition that includes an insoluble polymer matrix and a second solution, wherein the insoluble polymer matrix includes a plurality of nanovoids that are filled with the second solution; and removing a major portion of the solvent from the second solution. An apparatus for the process is also described, and includes a webline, a coating section, a partial polymerization section, and a solvent removal section.

  • Publication number: 20140243439
    Abstract: Techniques, mixtures and improved porous materials (interconnected porous constructs) that are capable of maintaining a sufficient porosity while conferring improved mechanical and physical strength to the final construct. A sacrificial construct (for example, a sacrificial material such as polymethyl methacrylate (PMMA)) is used to obtain an inverse porosity of the construct it was molded into. The process provides a less porous end material that may be used as an arthroplasty device or surgical implant (for example, an interference screw of suture anchor) among many other applications. The process employs a sacrificial material to reduce the porosity of the final construct to about 35%.

  • Publication number: 20140228463
    Abstract: A porous polymer structure may be formed by cooling a substrate to a temperature at or below a freezing point of a monomer, wherein the monomer is capable of free-radical polymerization; exposing the substrate to an initiator and the monomer, each in a vapor phase, wherein a concentration of the monomer in the vapor phase is above a saturation pressure of the monomer; converting the initiator to a free radical; crystalizing and depositing the monomer on the substrate; and polymerizing at least some of the monomer on the substrate, thereby forming a porous polymer structure on the substrate.
