  • Research:
    Large amplitude oscillatory shearing (LAOS) study on sol-gel phase transition of physical gels.

    Polymer gels crosslinked by non-covalent interactions constitute a transient type of networks that can exhibit multiple rheological behaviors under different conditions, one example of which being the sol-gel phase transitions. Large amplitude deformations, compared to small amplitude ones, are more close to the working conditions of most applications of commercial soft materials. Oscillatory experiment, on the other hand, separates the time-scale and deformation factors in rheology to give clearer picture of the materials at molecular level. Use of large amplitude oscillatory shearing (LAOS) to probe the sol-gel phase transition of physical gels may hopefully provide useful detail in this process.
