Poisson's ratio of polyacrylamide (PAAm) gels

Abstract Poisson's ratio ( ¦Ì0) of polyacrylamide (PAAm) gels was estimated. The value of ¦Ì for PAAm gels was found to be 0.457, which is close to that for poly (vinyl alcohol) (PVA) gels swollen in the mixture of dimethylsulfoxide (DMSO) and water, but is higher than the value for PVA hydrogels. article article

Swelling and de-swelling of gels under

Reports evaluating the Poisson ratio often assume that there is no change in cross-linking density [9], [10], or assume the dilute limit [8], neither of which may be valid in practice. Indeed, for PAAm gels, Li et al. reported an increase in the equilibrium Poisson ratio with added cross-linker, moving from 0.26 to 0.35 [11].

Inverse mechanical-swelling coupling of a highly deformed

10 May 2023 Vol 9, Issue 19 DOI: 10.1126/sciadv.abp8351 Abstract Mechanical behaviors of a polymer gel are coupled with its swelling behavior. It has been known that typical hydrogels display extension-induced swelling and drying-induced stiffening, called normal mechanical-swelling coupling.

Its Poisson ratio was found to decrease smoothly from 0.50 to 0.26, with an accompanying reduction in force. The equilibrium result compares well to the 0.25 value predicted by a theory of the strain-induced swelling of dilute gels.

crystal elastomer (CLCE), and a polyacrylamide gel (PAAm) in water, were used to determine the temporal resolution. A 10min video short at 25fps was used to evaluate the time dependence of the 3D-LCE over which time an increase in the Poisson ratio was observed. The 3D-LCE relaxes from its initial state at 0.42
