Abstract
The structure factor Ŝ(k) and the correlation length ξ for semiflexible polymer solutions were formulated using the generalized Ornstein–Zernike (GOZ) integral equation for the monomer-units pair correlation functions. The derived expression for Ŝ(k) contained the Fourier transform C(k) of the direct correlation function C(r) involved in the GOZ equation. Taking advantage of the short range nature of C(r), we calculated C(k) from the scaled particle theory, which was previously shown to successfully describe thermodynamic quantities of semiflexible polymer solutions. The present theoretical approach gave Ŝ(k) and ξ which were favorably compared with the previously obtained experimental results for dilute through semidilute solutions of a semifiexible polymer poly(n-hexyl isocyanate) dissolved in a good solvent dichrolomethane.
