Method for preparing fluorine-silicon-containing polyphosphate ester and flame retardant epoxy resin
Patent number: 11046816Abstract: 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.Type: GrantFiled: November 23, 2017Date of Patent: June 29, 2021Assignee: Xiamen UniversityInventors: Lizong Dai, Ting Chen, Cheng Liu, Shicheng Wang, Guorong Cehn, Conghui Yuan, Yiting Xu, Birong Zeng, Wei'ang Luo, Kaibin He -

Patent number: 9999599Abstract: 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.Type: GrantFiled: September 10, 2013Date of Patent: June 19, 2018Assignee: University of MassachusettsInventors: Sankaran Thayumanavan, Conghui Yuan
