{"product_id":"csspetiaibn","title":"AIBN (Azobisisobutyronitrile) Powder as Thermal Initiator for Solid-State Polymer Electrolyte, 20-100 g\/bottle, CSSPETIAIBN","description":"\u003cp\u003eUsing AIBN (Azobisisobutyronitrile) as a thermal initiator for in-situ polymerization is one of the most widely adopted strategies to fabricate solid-state polymer electrolytes. This approach effectively bridges the processing gap between liquid electrolytes and conventional solid state films. Instead of dry-casting and mechanically laminating a thick polymer membrane, a low-viscosity liquid precursor solution—containing monomers, lithium or sodium salts, and AIBN—is injected directly into an assembled cell. Upon mild heating, it cures into a solid matrix right in the pores of the electrodes.\u003c\/p\u003e\n\u003cp\u003eAIBN functions via a classic free-radical solution polymerization pathway. (1) \u003cstrong\u003eRadical Generation (Initiation)\u003c\/strong\u003e: When heated, typically to 60°C – 80°C, the central azo group (-N=N-) in AIBN undergoes homolytic cleavage.
