Case Study

Self-Healing Nanocomposite Hydrogel Cross-Linked with Zirconium Hydroxide Nanoparticles

Jiang, Haoyang, et al. Composites Science and Technology, 2017, 140, 54-62.

This work synthesised a zirconium hydroxide (Zr(OH)4) cross-linked nanocomposite hydrogel (Zr-NC gel) using the non-covalent hydrogen bonding between polymer chains and zirconium hydroxide. The optimised Zr-NC gel is tensile (404.3 KPa), compressive (36.6 MPa) and self-healing (86%) by adjusting the ratio of zirconium hydroxide and AMPS/AM molar.
Preparation of Zr-NC gels
· In-situ free radical copolymerisation of 2-acrylamido-2-methyl propane sulfonic acid (AMPS) and acrylamide (AM) in different molar ratios yielded Zr-NC gels, which were kept constant at a total monomer concentration of 2 mol/L.
· A given amount of Zr(OH)4 colloidal solution was added to room temperature deionised water. AM and AMPS monomers were added in the sequences to this solution, then nitrogen gas was forced through the solution, stirring continuously, for 15 minutes. Its resultant product was then ice-cooled to 0°C for 10 minutes in an ice-water bath. After vigorous stirring for 3 more minutes, 8 µl of TEMED and 0.5 ml of 2 wt% KPS solution were slowly added.
· The mixture was subsequently transferred to a glass tube where in-situ free radical polymerization was allowed to occur at room temperature for 72 hours. Finally, the hydrogels were washed to eliminate any unreacted monomers. The composition of the Zr-NC gels is denoted as AM m-Zr n-gel, where the values for m and n varied within the ranges of 50-90 and 2-12, respectively.
