WebApr 13, 2024 · By modifying the side chain's structure and length, it is possible to modify the graft copolymer's shape and, in turn, alter the proton transport channel and hydrophilic ion cluster sizes to achieve the desired properties. 18 To create the graft copolymer depicted in Figure 4b, Li et al. 41 grafted the side chain of poly aryl ether sulfone (PAES) onto the side … WebKuhn length b, packing length p, tube diameter a, and the overlap parameter for entanglement P e, all at temperature T. Since P e is apparently a polymer-independent constant, Eq. (25.10) suggests that the tube diameter and packing length are proportional, and the constant of proportionality thus has the empirical temperature dependence [1,2]:
