Maximally Stiffening Composites Require Maximally Coupled Rather Than Maximally Entangled Polymer Species
Davide Michieletto, Robert Fitzpatrick, Rae M Robertson-Anderson
Polymer composites are ideal candidates for next generation biomimetic soft materials because of their exquisite bottom-up designability. However, the richness of behaviours comes…
Synergistic interactions between DNA and actin trigger emergent viscoelastic behavior
Robert Fitzpatrick, Davide Michieletto, Karthik R. Peddireddy +4
Composites of flexible and rigid polymers are ubiquitous in biology and industry alike, yet the physical principles determining their mechanical properties are far from understood.…
Entanglement Density Tunes Microscale Nonlinear Response of Entangled Actin
Bekele Gurmessa, Robert Fitzpatrick, Tobias T. Falzone +1
We optically drive a microsphere at constant speed through entangled actin networks of 0.2 - 1.4 mg/ml at rates faster than the critical rate controlling the onset of a nonlinear r…
