WebFlory’s Characteristic Ratio (𝐶 ∞) is a coefficient used in the statistical mechanics of chain molecules to describe a polymer’s idiosyncratic tendency to deviate from an ideal worm-like chain behavior. The infinity symbol denotes the assumption that the chain is sufficiently long for the characteristic ratio to be a constant value.

WebGiven the Flory characteristic ratio: C∞ = /(n*l^2), we find = nk*lk^2, and we can find the Kuhn Length: lk = sqrt(/nk). This gives the length of a continuous straight segment of a chain of a polymer species, where the larger Kuhn Length is proportional to a more rigid chain WebThe genius of the Flory theory lies in the assumption that we can consider a real polymer chain as composed of two components: an ideal chain (entropic contribution) and …
