Summary: Poly(2-oxazoline)s are promising for biomedical applications, but limited synthetic approaches exist for star-shaped polymers. A novel bis-oxazoline cross-linker was developed via a fast thiol click reaction, allowing the preparation of well-controlled core cross-linked star polymers. The synthesized star-shaped polymers were characterized extensively and showed potential for encapsulation of dihydroxyanthroquinone.

Summary: The study reports on the synthesis and temperature-responsive properties of poly(PEGMA) hydrogel thin films. Surface-attached poly(PEGMA) hydrogel films were synthesized using a simple, versatile, and well-controlled thiol-ene click reaction method, with the transition temperature finely tunable by adjusting the number of PEG units. The LCST properties of the hydrogel films are not sensitive to salt, holding promise for applications in biology such as injectable hydrogels, drug delivery systems, microfluidic valves, and flow switches for biotechnologies.

Summary: Graphene films have high electrical conductivity and good mechanical strength, making them ideal for use in supercapacitors. However, their low elastic deformation ability limits their application in stretchable supercapacitors. By combining graphene with a conductive polymer hydrogel, the resulting composite film exhibits improved ductility and higher specific capacitance. A proof-of-concept planar supercapacitor using this graphene-conductive polymer hydrogel composite film as electrodes retains excellent electrochemical performance even under stretching conditions.

Summary: This study investigates the adsorption behavior of polymers on graphene oxide (GO) nanosheets by preparing a series of PEG/GO nanohybrids with different experimental parameters. The results show that the adsorption amount of PEG onto GO is influenced by factors such as mixing time, molecular weight, mixing ratio, and washing procedure. Additionally, the adsorption onto GO reduces the crystallinity of PEGs.
