Abstract Ionogels are widely studied as promising ionic thermoelectric (i‐TE) materials to harvest low‐grade waste heat into electrical energy due their huge thermopower and good conductivity, providing a feasible way sustainable development. Herein, p‐type i‐TE cellulose ionogel (CIG) based on Soret effect is prepared by dissolving in an liquid (IL) subsequent water‐absorbing induced gelation. Its morphological structure IL distribution intuitively investigated through cryo‐focused ion beam‐scanning electron microscope. Experimental characterizations molecular dynamic simulation studies elucidate that the regulation of water content induces hydration 1‐butyl‐3‐methylimidazolium cation swelling CIG, which greatly promotes ions diffusion expands difference mobility between anions cations. The proposed CIG exhibits superior properties: conductivity 51.2 mS cm −1 , Seebeck coefficient 20.7 mV K figure merit zT i 2.36 at 30 °C, respectively. A CIG‐based device designed assembled demonstrate its great potential for wearable body heat‐to‐electricity conversion. skeleton completely biodegradable nature used recyclable reusable, green strategy harvesting.

Lignin containing cellulose nanofiber/Ag₂Se nanocomposite films: a promising material for thermoelectric film generators

RSC Advances, Год журнала: 2024, Номер 14(34), С. 24756 - 24764

Опубликована: Янв. 1, 2024

This work deals with the fabrication of lignin containing cellulose nanofiber (LCNF)/Ag2Se films for thermoelectric applications. Ag2Se nanoparticles were synthesized within LCNF network through in situ methods, employing Na2SeO3 and AgNO3 along microwave energy treatment. LCNF/Ag2Se fabricated two : weight percent ratios (i.e., 50 30 70) used to construct a flexible module. The obtained displayed uniform size distribution smaller dimensions from treated group. microstructure was improved by hot-pressing, leading enhanced film density properties. At differential temperature K, 50% 70% exhibited output voltages 18 21 mV; Seebeck coefficients -60 -70 μV K-1 at 350 respectively. When applied, showed highest 19 33 mV, respectively, -63.3 -110 K. low-cost process associated this module opens pathway applications such as harvesting.
