The development of a crosslinked hydrogel is well described in quiescence and in bulk rheology. However, shear forces are well known to affect the formation of gels, both in terms of gelation time scales and final gel properties. Shear forces change the dominant mechanisms of crosslinking and aggregation: in shear, intramolecular crosslinking is favored over intermolecular crosslinking, and diffusion-limited clustering gives way to shear-induced cluster-cluster interactions . Final cluster size is limited by shear, preventing the complete percolation of crosslinking networks . As such, bulk rheology experiments demonstrate that the growth of polymer gels is delayed by shear, since the ability of aggregates to form a percolated network is compromised by disruption of inter-aggregate bonds . At sufficiently high shear rates, gelation is completely inhibited . Further, gels formed in shear tend to be weaker than their counterparts formed in quiescence . These effects, while observed in bulk rheology, have not been studied in pressure-driven flow, nor within a microfluidic environment with shear gradients. However, understanding the behavior of gels in these environments is crucial in several applications, including 3D bioprinting.
