Title: Innovations of Richard P. Chartoff
Introduction
Richard P. Chartoff is a notable inventor based in Cincinnati, OH, with a significant contribution to the field of materials science. He holds a total of seven patents, showcasing his expertise and innovative spirit. His work primarily focuses on the development of advanced materials, particularly those involving liquid crystal monomers.
Latest Patents
One of his latest patents is titled "Methods and apparatus for producing ordered parts from liquid crystal monomers." This invention describes a method and apparatus for creating ordered parts from non-ordered liquid crystal monomers. The liquid crystal monomers contain stiff, rod-like mesogenic segments that can be aligned using external forces such as shear, electric fields, or magnetic fields. This alignment results in anisotropic properties, which are "locked in" when the aligned monomers are cured through photopolymerization. The resulting materials exhibit anisotropic physical and mechanical properties, with glass transition temperatures ranging from 75 to 148 °C, depending on the resin and processing conditions. Additionally, a mechanical anisotropy on the order of two was measured for aligned samples.
Another significant patent by Chartoff is for "Rigid rod monomers and polymers for use in rapid prototyping, composites, and adhesives." This invention provides rigid-rod monomers and polymers suitable for applications in rapid prototyping, composites, and adhesives. The monomers can be photocured through their end groups and thermally post-cured through acetylene groups, resulting in a highly crosslinked polymer with an effective glass transition temperature exceeding 200 °C.
