Self-repairing polymers: poly(dioxaborolane)s containing trigonal planar boron.
The molecular weight of poly(dioxaborolane)s can be controlled during the polymerization reaction or through post-polymerization processing in such a manner that hydrolytic damage to these materials may be repaired, thereby regenerating the polymer.
متن کاملLow-Temperature Self-Healing of a Microcapsule-Type Protective Coating
Low-temperature self-healing capabilities are essential for self-healing materials exposed to cold environments. Although low-temperature self-healing concepts have been proposed, there has been no report of a microcapsule-type low-temperature self-healing system wherein the healing ability was demonstrated at low temperature. In this work, low-temperature self-healing of a microcapsule-type pr...
متن کاملMicrocapsule induced toughening in a self-healing polymer composite
Microencapsulated dicyclopentadiene (DCPD) healing agent and Grubbs’ Ru catalyst are incorporated into an epoxy matrix to produce a polymer composite capable of self-healing. The fracture toughness and healing efficiency of this composite are measured using a tapered double-cantilever beam (TDCB) specimen. Both the virgin and healed fracture toughness depend strongly on the size and concentrati...
متن کاملSelf-healing Polymers
These images present the dramatic reduction in corrosion of a steel plate coated with a self-healing coating (right) as compared to a conventional coating. Both samples were scratched and placed in 5% NaCl for 5 days. The background is an optical image (2x magnifi cation), in the foreground is an SEM image of the scratch. In the self-healing sample, the scratch has almost completely self-healed...
متن کاملSelf-immolative polymers.
The investigation of synthetic polymers for biological applications is increasing as assembly techniques for generating welldefined macromolecules from artificial building blocks become more sophisticated. Synthesis techniques have now evolved such that a wide variety of functional groups can be tolerated by polymerization catalysts, and a fascinating and diverse range of macromolecular and pol...
