  • Patent number: 11046816
    Abstract: Disclosed are a fluorine-silicon-containing polyphosphate ester and method for preparation thereof, having a chemical structural formula of: wherein R1 is R2 is n=10˜100. The fluorine-silicon-containing polyphosphate ester of the present invention uses silicon phosphorus and fluorine for improving flame retardancy. Phosphorus catalyzes the system to form a phosphorus-rich carbon layer, performing a protective-layer function and thereby preventing further breakdown of the epoxy resin. The silicon-containing epoxy resin forms a silica-containing carbon layer during the process of combustion, strengthening the carbon-layer structure and further improving the protective function of the carbon-layer. The introduction of elemental fluorine improves the thermal stability of the epoxy resin, thereby improving the flame retardancy performance of the system.

  • Patent number: 10189981
    Abstract: The present invention provides a method for preparing high-strength cross-linked polymer photonic crystal film by core-shell polymer microspheres via evaporation-induced self assembly. Monodispersed core-shell polymer microspheres are fabricated by emulsifier-free emulsion polymerization, and then the microspheres emulsion is coated onto suitable substrates. Finally, polymer photonic crystal film with long-range ordered is constructed via self assembly. Self-cross-linking between the two units improves the strength of the polymer photonic crystal film, therefore the preparation of large size industrial-grade photonic crystal film is practicable which extends its application on the field of dyeing.

  • Patent number: 9999599
    Abstract: The invention provides novel nanoscale delivery vehicles and composite nanoassemblies built from distinct nanoassembly units (e.g., block copolymer micelles and nanogels) with stoichiometric control. These intelligent composite nanoassemblies independently retain the key features of the nanoassembly units and greatly expand the potential functional features attainable based on the surface functionalization. The invention provides a novel approach to constructing nano-vehicles with controllable morphology based on combination of cooperative releasing mechanisms (e.g., redox sensitive nanogels and pH sensitive micelles). Two kinds of guests can be seperately and stably encapsulated in the composite nanocontainers, and then released sequentially under the stimulation of pH change and reduced glutathione.
