B size. The exponent 2 is normally obtained for linear sponding towards the thermal blob size. The exponent two is typically obtained for linear polymers polymers in semi-dilute -solutions, adopting awalk conformation [66]. Having said that, a fractal in semi-dilute -solutions, adopting a random random stroll conformation [66]. Nevertheless, a fractal exponent 1.7 (equivalent tobeen also been also to correctly describe I(q) for bigger exponent 1.7 (equivalent to 5/3) has 5/3) has reported reported to correctly describe I(q) for larger domain size two that corresponds for the arrangement from the smaller sized domains domain size 2 that corresponds to the arrangement on the smaller sized domains represented represented by 1 to swallowed agglomerates (see also Figure two) [66]. At these scale lengths, by 1 to swallowed agglomerates (see also Figure 2) [66]. At these scale lengths, the chain the chain conformation is a self-avoiding walk of thermal blobs. Thus, accordingly, conformation is really a self-avoiding stroll of thermal blobs. Therefore, accordingly, I(q) = =OZ (0)/[1 + (q 2 )5/3 ] ] I(q) I IOZ(0)/[1 + (q2)5/3 (9) (9)Plotting the inverse of I(q), i.e., I(q)-1,, against q2 and q5/3 as described in Equations (10) Plotting the inverse of I(q), i.e. I(q)-1 against two and 5/3 as described in Equations and (11), respectively, will bring about straight lines, from which x11 and x2 can be extracted: respectively, will bring about straight lines, from which x and xI(q) = IOZ (0)-1 + I IOZ(0) q q I(q)-1 -1 = IOZ(0)-1 +OZ (0)-1-11 2122I(q)-1 = IOZ (0)-1 + IOZ (0)-1 two 5/3 q5/(ten) (ten)(11)Polymers 2021, 13, x FOR PEER REVIEW14 ofPolymers 2021, 13,I(q)-1 = IOZ(0)-1 + IOZ(0)-125/3q5/3.
