Correlation and scattering functions in a lattice model of oil–water–amphiphile solutions

摘要: The scattering function is calculated in mean‐field approximation for two different thermodynamic states of a lattice model oil–water–amphiphile solutions, one disordered state and the other one‐dimensionally ordered (lamellar) state. total former, fluctuation contribution to latter, have maxima near q=1, where q magnitude vector units reciprocal spacing. For up little beyond maximum functions their spherical averages (averaged over surface sphere radius space) are Teubner–Strey form I(q)=I(0)/(1−bq2+cq4) with b c both positive, as microemulsions. It implies correlation that an exponentially damped sinusoid, wavelength d attenuation length, determined by c.
