Polymers having mechanical properties approaching or exceeding commercial elastomers and engineering thermoplastics, but improved biostability, are described herein. In one embodiment, the polymers have a hard segment containing one or more disulfoxide or disulfone moieties and a soft segment connected to the hard segment to form an elastomeric polymer. The polymer is resistant to oxidation and/or hydrolytic degradation, particularly in vivo, which allows for the use of these materials in implants/devices which are implanted for an extended period of time. The ratio or percentage by weight of soft segment to hard segment can be varied based on the physical and mechanical properties of the desired device.

Degradable sulfur-containing hyperbranched epoxy resin and a preparation method thereof. The preparation method comprises initiating a reaction of a mercaptocyclotriazine compound and a binary olefin by ultraviolet light to prepare a mercapto hyperbranched polymer; then reacting with glycidyl methacrylate to obtain a degradable sulfur-containing hyperbranched epoxy resin of which the molecular weight is about 3,000-35,400 g/mol. After the degradable sulfur-containing hyperbranched epoxy resin is cured, a cyclotriazine structure can be completely degraded within 1.5 h in a phosphoric acid solution at the temperature of 80 DEG C, thus realizing the recycle of the epoxy resin. The invention is simple in process, low in reaction temperature, rapid in reaction and high in yield, the sulfur-containing structure lowers curing temperature and realizes rapid curing, and cyclotriazine structure has a degradation function, and is expected to be used in the fields of strengthening and toughening of the epoxy resins, solvent-free coatings, electronic packaging.

Functionalizable nanopatterned monolayers comprise one or more block copolymers, each containing one or more hydrophobic blocks and one or more hydrophilic blocks. The one or more hydrophilic blocks of at least one of the block copolymers can be terminated by a modifiable functional group, to which a functional moiety, such as a biological molecule, can be attached. The surface concentration of the modifiable functional groups on the monolayer can be controlled by adjusting the properties of the block copolymers, such as their size, their chemical makeup, and the relative proportion of the block copolymer containing the modifiable functional group, and the conditions, such as surface pressure, under which the monolayer is formed and/or transferred to a substrate. The nanopatterned monolayer can be transferred to a substrate to form a functionalizable nanopatterned nanocoating, which is useful in applications such as biosensors.
