Abstract Thermoelectric materials, as key materials for realizing efficient conversion of thermal and electrical energy, are crucial renewable energy utilization management. However, with high negative thermoelectric coefficients relatively rare. Herein, inspired by the structure function plant stem which is capable blocking heavy metal ions, chitosan/CuCl 2 hydrogel (ChCu) a huge coefficient reported. The ChCu displayed lamellar porous structure, constructed synergistically freeze‐casting technique complexation between Cu 2+ chitosan. In subjected to temperature gradient, most immobilized within chitosan matrix complexation, while migration unbound further intercepted special layered structure. On contrary, Cl − migrates unhindered cold end accumulates, realizes selective distribution ion/counterion. As result, exhibits ‐23.8 mV K −1 , can respond rapidly voltage 4.0 under small difference (ΔT = 0.3 K). This work reveals significant influence polymer aggregate on diffusion providing an innovative strategy in designating high‐performance, high‐efficiency environmentally friendly.
