摘要:
Methods of forming nanostructures with chromonic materials are disclosed. A method includes coating a substrate surface with a chromonic solution to form a chromonic layer, removing at least a portion of the water to form a dried chromonic layer, and exposing the dried chromonic layer to an organic solvent to form a pattern of channels within the dried chromonic layer. The chromonic solution includes a chromonic material and water. Materials can be deposited within the channels to form a pattern of nanostructures.

摘要:
A method for forming channels within a dried chromonic layer is described. A coating composition is applied to a substrate, dried, and exposed to a hydrophilic organic solvent forming a channel pattern having a first set of channels, and a second set of channels that are substantially perpendicular to the first set of channels. A deposition material may be disposed within the channels to form a nanostructured pattern. An article having a channel pattern is further described.
摘要:
A pre-adhesive composition is described comprising an acid- and epoxy-functional (meth)acryloyl copolymer, which when crosslinked using an ionic photoacid generator (PAG) provides a pressure-sensitive adhesive and pressure-sensitive adhesive articles having desirable properties.

摘要:
The present invention provides compositions comprising epoxy-containing monomers, where the polymerization of the monomers can be influenced by accelerators. The compositions include at least one photo-polymerizable epoxy monomer and an initiation system. The initiation system comprises at least one organo-iron complex salt and at least one accelerator. The epoxy-containing monomers are energy-polymerized to form useful articles or coated articles.

A stabilized heat curable adhesive prepared from a formulation comprised of (1) at least one free radically polymerizable monomer; (2) at least one epoxy function monomer; (3) at least one free radical polymerization photoinitiator; (4) a thermally-initiated cationic catalyst system comprising (a) at least one salt of an organometallic cation, (b) at least one stabilizing additive; (5) optionally, at least one alcohol-containing material; and (6) optionally, adjuvants.
摘要:
Hardenable and hardened dental compositions that include radiation-to-heat converters, and articles including such hardenable and hardened compositions, are provided. Upon irradiating, the hardened compositions increase in temperature, which can be useful for reducing the bond strengths of orthodontic appliances adhered to tooth structures with the hardened compositions.
