摘要： A method for manufacturing a play-of-color article includes the steps of: (a) providing a first mixture that contains a solvent and a plurality of functionalized colloidal particles; (b) replacing the solvent of the first mixture with a polymer solution that contains polymers, thereby obtaining a second mixture; (c) adding an initiator to the second mixture to obtain a third mixture, followed by injecting the third mixture into a mold and disturbing the third mixture, so that the third mixture is formed with a pattern; (d) leaving the third mixture to stand, so as to allow the functionalized colloidal particles therein to self-assemble to form a crystalline arrangement, thereby obtaining a fourth mixture; and (e) subjecting the polymers in the fourth mixture to a cross-linking reaction, thereby obtaining the play-of-color article. A play-of-color article manufactured by the method, and a play-of-color product including the play-of-color article are also provided.

摘要： A composition and a method are provided for graphene reinforced polyethylene terephthalate (PET). Graphene nanoplatelets (GNPs) comprising multi-layer graphene are used to reinforce PET, thereby improving the properties of PET for various new applications. Master-batches comprising polyethylene terephthalate with dispersed graphene nanoplatelets are obtained by way of compounding. The master-batches are used to form PET-GNP nanocomposites at weight fractions ranging between 0.5% and 15%. In some embodiments, PET and GNPs are melt compounded by way of twin-screw extrusion. In some embodiments, ultrasound is coupled with a twin-screw extruder so as to assist with melt compounding. In some embodiments, the PET-GNP nanocomposites are prepared by way of high-speed injection molding. The PET-GNP nanocomposites are compared by way of their mechanical, thermal, and rheological properties so as to contrast different compounding processes.

摘要： A family of novel diazirine-based molecules is disclosed, as well as methods of manufacture and uses thereof. These compounds allow non-functionalized polymers, such as polyolefins, to crosslink via C—H insertion. Such a C—H insertion process is useful, for example, for the covalent adhesive bonding of low surface energy films or materials, or for creating rigid 3-dimenional polymeric structures by in-situ doping and activation of the crosslinker. The disclosed crosslinkers can be activated thermally, by UV radiation or by an electric potential.

摘要： Certain embodiments of the invention described herein comprise a composition of matter, and method for preparing the same, which provide the benefits of pre-reaction molecular configuration favoring high liquidity properties, and post-reaction configuration that favors mechanical strength, stiffness, and properties associated with high viscous and/or solid-state materials. In some embodiments, the composition of matter can comprise relaxing photo-isomerizable fragments, of which a fraction can be transformed from trans to cis configurations upon exposure to a photon source. In some embodiments, the composition of matter further comprises thermally reactive fragments, of which can enable thermal solidification of a mixture upon exposure to elevated temperatures. In some embodiments, a composition of matter can be combined with reinforcing additives to form a prepreg combination.

摘要： In some examples, novel photochemically-reversible hydrogels and nanogel particles are described comprising copolymer chains including at least one reactive alkene or reactive 1,4-diene end group capable of [2+2] or [2+2+2+2] photodimerization, respectively, at wavelengths >270 nm. In various examples, the photochemically-reversible hydrogels comprise copolymer chains including at least one —N3, —C≡CH or —CO2H end group for dual functionality and/or pH responsiveness. For nucleic acid sequencing, amplification primers are grafted to photochemically-reversible hydrogels or nanogel particles reversibly bound to surfaces within a flow cell. After sequencing is complete, the photochemically-reversible hydrogel or nanogel particles is/are removable from the flow cell surfaces by irradiation, enabling the flow cell to be reusable.

摘要： Described herein are compositions and methods that utilize complementary polymerization reactions to simultaneously generate one or more polymeric materials, including crosslinked polymer matrices, tethered inter-penetrating network, heterogenous polymer blends, or homogeneous polymer blends. The provided compositions and methods utilize the combination of an energy demanding step-growth reaction with a highly exothermic reaction to drive the energy demanding reaction by chemical heating and avoid issues associated with thermal runaway, such as solution boiling or unwanted biproducts.
