A macromolecular photonic crystal material including an A block and a B block is disclosed. 1wherein the A block comprises a crystalline polyhedral oligomeric FOSS, the macromolecular photonic crystal material represented by the structural formula 1.. A macromolecular photonic crystal material including an A block and a B block, This application claims the priority of U.S. Provisional Patent Application No. 62/558,880 filed on Sep. 17, 2017; Korean Patent Application No. 10-2018-0111136 filed on Sep. 17, 2018 in the Korean Intellectual Property Office, the disclosure of which is hereby incorporated by reference in its entirety.Discloses a macromolecular polymer photonic crystal material containing polyhedral oligomeric silsesquioxane (POSS).Block copolymers are widely used as organic polymer photonic crystal materials. Brush block copolymers through polymerization of double norbornene macromonomers have commercial disadvantages as they require precise polymerization techniques.Cube-like polyhedral oligomeric silsesquioxane (POSS) is a promising candidate of isotropically bulky pendants to expand the dimensional limit of polymer main chains. This paper presents molecular and kinetic insights into the controlled synthesis of rod-like POSS-containing polynorbornenes. Ring-opening metathesis polymerization (ROMP) was performed on three norbornene-substituted POSS monomers with different spacers. For monomers possessing non- and amide functionalities at the spacers, ROMP at the maximum concentration ([M]=0.4 M) led to 100% conversion, predictable molecular weights (M≤1236 kDa) and low dispersities (Ð≤1.20) in homopolymers. Scaling analysis for POSS-containing polynorbornenes revealed an unusual finding, namely, that the periodic clustering of POSS pendants favored by long flexible spacers (16-atom chains) enhanced the rigidity of polynorbornene main chains, leading to their rod-like conformation. Kinetically optimized ROMP allowed the subsequent addition of a ...

Catalyst-lean, microcapsule-based self-healing materials via ring-opening metathesis polymerization (romp)

Номер: US20170152380A1
Принадлежит: International Business Machines Corp

A self-healing composite material includes a polymer matrix, microcapsules filled with a ring-opening metathesis-active monomer (e.g., norbornene, norbornene derivatives such as ethylidene norbornene, or cyclooctadiene), and polymeric particles comprised of a polymer that is soluble in the monomer with which the microcapsules are filled and having catalytic endgroups derived from an olefin metathesis catalyst, such as a Grubbs'-type catalyst. In some embodiments, the polymer having catalytic endgroups is synthesized via solution polymerization of a ring-opening metathesis-active monomer (e.g., norbornene, norbornene derivatives, or cyclooctadiene) in the presence of an olefin metathesis catalyst (e.g., Grubbs' 1st generation catalyst). The polymer having catalytic endgroups may then be processed via a grinding operation, for example, to prepare the small polymeric particles. In other embodiments, the polymeric particles are synthesized directly as microparticles (e.g., microspheres, granules, beads, etc.) utilizing an analogous suspension polymerization.
