Disclosed are a hyaluronic acid-based zwitterionic polymer brush, a preparation method thereof, and the use thereof. The structure of the zwitterionic polymer brush is represented by formula (I), wherein n is an integer from 60-150, x is an integer from 589-686, and y is an integer from 125-230. The above-mentioned zwitterionic polymer brush can delay the pathological progress of osteoarthritis, promote cartilage regeneration, and even treat osteoarthritis and improve conditions such as the generation of abraded fragments of implants such as joints and related diseases triggered thereby, and can be combined with cartilage repairing materials to improve the frictional mechanical properties thereof for achieving better repair results. Moreover, the above-mentioned zwitterionic polymer brush can selectively bind to proteins in cartilage and has an excellent lubricating effect. The present invention has the advantages of simple method, convenient operation, easy purification, high yield, and the like.

A poly(vinylphosphonic acid) (PVPA)(NH.sub.4).sub.2MoO.sub.4), gel polymer electrolyte can be prepared by incorporating redox-mediated Mo, or similar metal, into a PVPA, or similar polymer, matrix. Gel polymer electrolytes including PVPA/MoX, x representing the percent fraction Mo in PVPA, can be used to make supercapacitors including active carbon electrodes. The electrolytes can be in gel form, bendable and stretchable in a device. Devices including this gel electrolyte can have a specific capacitance (Cs) of 1276 F/g, i.e., a more than 50-fold increase relative to a PVPA system without Mo. A PVPA/Mo10 supercapacitor can have an energy density of 180.2 Wh/kg at power density of 500 W/kg, and devices with this hydrogel structure may maintain 85+% of their initial capacitance performance after 2300 charge-discharge cycles.
