  • Can cellulose nanofibers strengthen polyacrylamide gels through in situ free radical polymerization?
  • Cellulose nanofibers (CNFs) have emerged as a promising nanofiller for effective reinforcement of nanocomposites due to their excellent mechanical properties. In this study, CNFs were fabricated by a simple grinding method and used to strengthen polyacrylamide (PAM) gels through in situ free radical polymerization.
  • Does cellulose nanofiber enhance mechanical properties of hydrophobically associated polyacrylamide hydrogels?
  • Zhang, Y. et al. Enhancement of mechanical property and absorption capability of hydrophobically associated polyacrylamide hydrogels by adding cellulose nanofiber. Mater. Res. Express 7, 15319 (2025). This work was partially supported by JSPS KAKENHI (JP18H03551).
  • How TEMPO oxidized cellulose nanofibers improve fatigue resistance of polyacrylamide hydrogel?
  • TEMPO-oxidized cellulose nanofibers (TOCNs) with high strength and ultra-high aspect ratio were introduced to improve the energy dissipation mechanism and enhance the fatigue resistance of polyacrylamide (PAAM) hydrogel. Interestingly, the nanocomposite hydrogel displays unprecedented shape memory properties through coordination with Fe 3+.
  • Can nanocomposite hydrogel improve fatigue resistance of polyacrylamide (PAAM) hydrogel?
  • To tackle this, we develop a novel nanocomposite hydrogel by radical polymerization. TEMPO-oxidized cellulose nanofibers (TOCNs) with high strength and ultra-high aspect ratio were introduced to improve the energy dissipation mechanism and enhance the fatigue resistance of polyacrylamide (PAAM) hydrogel.
