Publication number: 20230119640Abstract: The present disclosure provides an antibacterial hydrophilic compound. The antibacterial hydrophilic compound may react, induced by light through a hydrogen abstraction group in the structural formula thereof, with a C—H group and thus bind to a surface of a material having the C—H group (for example, chemical fibers such as polyester, chinlon, and the like; plastics, rubbers, and other similar materials), which can impart a durable antibacterial activity and hydrophilicity to the material. The antibacterial hydrophilic compound has a relatively strong binding force to the surface of the material without damaging the mechanical properties of the raw material. The present disclosure also provides a modified material that is modified by the antibacterial hydrophilic compound.Type: ApplicationFiled: November 21, 2022Publication date: April 20, 2023Applicant: SHENZHEN UNIVERSITYInventors: Shiguo CHEN, Shaobo ZHANG, Xiaohua CAI, Zaochuan GE

Patent number: 10005866Abstract: The present disclosure relates to the field of shape memory materials, it discloses a betaine-based shape memory polymer and the preparation method thereof. The polymer is formed through free radical polymerization of an unsaturated betaine monomer, an acrylic monomer, and an ethylene glycol divinyl ether monomer with the addition of an initiator. The betaine-based shape memory polymer has thermosensitive shape memory property and wet sensitive shape memory property, and it has good biocompatibility and an excellent shape memory property, antibacterial property. It is of great potential for use in engineering, construction, daily life and medical service.Type: GrantFiled: August 22, 2016Date of Patent: June 26, 2018Assignee: SHENZHEN UNIVERSITYInventors: Shaojun Chen, Yangyang Chen, Funian Mo, Yan Yang, Shiguo Chen, Zaochuan Ge
