▎ 摘 要
NOVELTY - Formulation comprises: a hybrid composite material; at least one photopolymerizable monomer; at least one free radical photoinitiator and an oxidizable radical co-producer, where the hybrid composite material comprises an organic semiconducting material; and a conductive material, where the organic semiconducting material is bonded to the conductive material. USE - The formulation is useful for: initiating and/or sensitizing photopolymerization; and manufacturing additive (all claimed) e.g. to facilitate/enhance curing of three dimensional-printed polymer and polymer (nano)composites. ADVANTAGE - The formulation: enhances polymerization at longer wavelengths, lower energies, and faster rate, and to discover new photopolymer resins of acrylate and epoxy with better mechanical properties, thermal and electrical conductivity, and fire retardancy through reinforcement with nanofillers for application in additive manufacturing; and improves print quality and/or resolution. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) a kit of parts comprising (A) a first formulation comprising the hybrid composite material and a first portion of the photopolymerizable monomer, and (B) a second formulation comprising a second portion of the photopolymerizable monomer and the free radical photoinitiator and an oxidizable radical co-producer; (2) initiating and/or sensitizing (m1) photopolymerization, comprising (gi) mixing the hybrid composite material with a composition comprising the photopolymerizable monomer, and the free radical photoinitiator and an oxidizable radical co-producer to form a mixture, and (gii) exposing the mixture to a light in order to provide a polymer product; and (3) manufacturing (m2) additive comprising (hi) providing a mixture comprising the hybrid composite material, the photopolymerizable monomer, and the free radical photoinitiator and an oxidizable radical co-producer, (hii) forming a layer using the mixture according to a design, (hiii) subjecting the layer to light to provide a polymer, and (hiv) repeating steps (hii) and (hiii) until the desired design is complete. DESCRIPTION OF DRAWING(S) - The figure shows the process methodology of polydopamine and multiwalled carbon nanotube nanohybrids as photosensitizer/co-initiator.
