This study explores the innovative potential of native lignin as a sustainable biopolyol for synthesizing polyurethane aerogels with variable microstructures, significant specific surface areas, and high mechanical stability. Three types lignin—Organosolv, Aquasolv, Soda lignin—were evaluated based on structural characteristics, Klason content, particle size, Organosolv being identified optimal candidate. The microstructure samples was adjustable by solvent choice: Gelation in DMSO pyridine, affinity to lignin, resulted dense materials low while use low-affinity e.g acetone led aggregated, macroporous due microphase separation. Microstructural control achieved DMSO/acetone pyridine/acetone mixtures, which balanced gelation phase separation produce fine, homogeneous, mesoporous materials. Specifically, 75% mixture yielded mechanically stable envelope density 0.49 g cm−3 area ~300 m2 g−1. demonstrates versatile approach tailoring textural properties simple adjustment composition, highlighting critical role solvent–lignin interactions during offering pathway sustainable, high-performance
