Research demonstrates the fabrication of tunable porous polymers in cellulose-based aerogels, indicating structural versatility.

To explore the development and stabilization of water-in-oil emulsions for creating tunable porous polymers and aerogels.
Utilized TEMPO-oxidized cellulose nanofibrils modified with cationic surfactants as stabilizers.
Designed water-in-oil high internal phase emulsions with over 95% internal phase.
Adjusted reaction temperatures to control pore connectivity in porous polymers.
Synthesized one-pot hydrophobic aerogels with tailored structures.
Achieved near-superhydrophobic aerogels with a contact angle of approximately 147°.
Produced thermally insulating aerogels with a thermal conductivity of 26.7 mW/(m·K).
Demonstrated pore connectivity adjustment without complex formulation changes.
Enabled incorporation of functional additives to enhance flame retardancy and thermal stability.
