摘要： Methods of forming nanoporous materials are described herein that include forming a polymer network with a chemically removable portion. The chemically removable portion may be polycarbonate polymer that is removable on application of heat or exposure to a base, or a polyhexahydrotriazine (PHT) or polyhemiaminal (PHA) polymer that is removable on exposure to an acid. The method generally includes forming a reaction mixture comprising a formaldehyde, a solvent, a primary aromatic diamine, and a diamine having a primary amino group and a secondary amino group, the secondary amino group having a base-reactive substituent, and heating the reaction mixture to a temperature of between about 50 deg C. and about 150 deg C. to form a polymer. Removing any portion of the polymer results in formation of nanoscopic pores as polymer chains are decomposed, leaving pores in the polymer matrix.

摘要： Condensation polymers are prepared by agitating a mixture comprising glyoxal, a monomer comprising two or three primary aromatic amine groups, an organic solvent, and water at a temperature between 20° C. and 100° C. The resulting solution can be applied to a surface of a substrate, forming an initial film. Curing the initial film layer using two or more heating steps, wherein one of the heat steps is performed at a temperature of 150° C. to 250° C., produces a cured film layer. Depending on the relative amounts of glyoxal and monomer used, the film layer can contain predominantly high Tg imine-containing units or predominantly lower Tg aminal-containing units. All film layers were highly resistant to the solvent used to prepare the polymer. The Tg of the polymer can be about 190° C. to greater than 300° C.

摘要： A renewable material for releasing a self-healing agent includes a renewable polymeric substrate with capsules and a reactant dispersed in the renewable polymeric substrate. The capsules may be formed from a first renewable shell polymer and may enclose the renewable self-healing agent. The reactant may be suitable for reacting with the renewable self-healing agent to form a polymer.

摘要： A block copolymer is synthesized by polymerizing a silane-functionalized norbornene monomer in the presence of a catalyst system that includes a Ziegler-Natta catalyst and cocatalyst, followed by sequential addition and polymerization of a matrix-reactive functionalized norbornene monomer. In some embodiments, an enhanced substrate for a PCB is produced by applying the block copolymer to a substrate that includes glass fiber, followed by applying the base polymer to the substrate having the block copolymer applied thereto.

摘要： A carbene-coated metal foil is produced by applying an N-heterocyclic carbene (NHC) compound to one or more surfaces of a metal foil (e.g., an electrodeposited copper foil having a surface that is smooth and non-oxidized). The NHC compound contains a matrix-reactive pendant group that includes at least one of a vinyl-, allyl-, acrylic-, methacrylic-, styrenic-, amine-, amide- and epoxy-containing moiety capable of reacting with a base polymer (e.g., a vinyl-containing resin such as a polyphenylene oxide/triallyl-isocyanurate (PPO/TAIC) composition). The NHC compound may be synthesized by, for example, reacting a halogenated imidazolium salt (e.g., 1,3-bis(4-bromo-2,6-dimethylphenyl)-4,5-dihydro-1H-imidazol-3-ium chloride) and an organostannane having a vinyl-containing moiety (e.g., tributyl(vinyl)stannane) in the presence of a palladium catalyst. In some embodiments, an enhanced substrate for a printed circuit board (PCB) is produced by laminating the carbene-coated metal foil to a substrate that includes glass fiber impregnated with the base polymer.

摘要： A flame retardant filler having brominated silica particles, for example, imparts flame retardancy to manufactured articles such as printed circuit boards (PCBs), connectors, and other articles of manufacture that employ thermosetting plastics or thermoplastics. In this example, brominated silica particles serve both as a filler for rheology control (viscosity, flow, etc.) and a flame retardant. In an exemplary application, a PCB laminate stack-up includes conductive planes separated from each other by a dielectric material that includes a flame retardant filler comprised of brominated silica particles. In an exemplary method of synthesizing the brominated silica particles, a monomer having a brominated aromatic functional group is reacted with functionalized silica particles (e.g., isocyanate, vinyl, amine, or epoxy functionalized silica particles). Alternatively, a monomer having a brominated aromatic functional group may be reacted with a silane to produce a brominated alkoxysilane monomer, which is then reacted with the surface of silica particles.
