Patent number: 9403945Abstract: Polyhexahydrotriazine (PHT) and polyhemiaminal (PHA) materials form highly cross-linked polymers which can be used as binder resins in composite materials. A filler element functionalized with a primary amine group can be covalently bonded to the PHA/PHT polymer resins. Example filler elements include, without limitation, carbon nanotubes, silica materials, carbon and glass fibers, and nanoparticles. Filler materials are incorporated into polymeric materials to improve the mechanical strength or other characteristics of the polymeric material for various applications. Typical composite materials use thermosetting materials that, once set, are intractable. PHT and PHA materials can be reverted to starting materials by exposure to acids. Thus, composite components formed using these materials are recyclable.Type: GrantFiled: December 16, 2014Date of Patent: August 2, 2016Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Dylan J.

Patent number: 6207787Abstract: A co-polymer of benzophenone and bisphenol A has been shown to have DUV absorption properties. Therefore, the co-polymer has particular utility as an antireflective coating in microlithography applications. Incorporating anthracene into the co-polymer backbone enhances absorption at 248 nm. The endcapper used for the co-polymer can vary widely depending on the needs of the user and can be selected to promote adhesion, stability, and absorption of different wavelengths.Type: GrantFiled: November 20, 1998Date of Patent: March 27, 2001Assignee: International Business Machines CorporationInventors: James Thomas Fahey, Brian Wayne Herbst, Leo Lawrence Linehan, Wayne Martin Moreau, Gary Thomas Spinillo, Kevin Michael Welsh, Robert Lavin Wood
