Flory rehner方程
Web512 P. J. FLORY AND J. REHNER, JR. Equation (12) was used to find the curves shown in Fig. 1. The rate expression involving the acid chro mate ion is -d(Cr03)/dt = k(HCr04-) (CH3CHOHCH3) (H+)2. (6) The concentration of acid chromate ion can be calculated from the equilibrium expression where the parentheses indicate concentrations, WebThe phase coexistence observed around the first-order transition in NIPA gels cannot be interpreted by the Flory-Rehner theory because this theory tacitly assumes that the equilibrium state of a gel is always a homogeneous one. Heterogeneous structures such as two-phase coexistence are ruled out from the outset in this theory. Of course, if the …

WebWe therefore extend the classic Flory-Rehner theory of hydrogel swelling by coupling it to Hertzian contact mechanics that explicitly treats the stresses exerted by the medium at the hydrogel-grain contacts. Using this approach, we show that the extent of hydrogel swelling is determined by the balance between the osmotic swelling force exerted ...
