Lauric arginate/cellulose nanocrystal nanorods-stabilized alkenyl succinic anhydride pickering emulsion: enhancement of stabilization and paper sizing performance

Biodegradable colloidal particle materials are becoming attractive candidates as eco-friendly chemical additives in the low-carbon economy era. However, developing cheap, stable, and efficient paper-sizing agents is still a challenging issue for both paper-making academic community industry. Here, an easy-fabricating, high-performance alkenyl succinic anhydride (ASA) emulsion that stabilized by lauric arginate (LAE)/cellulose nanocrystals (CNCs) nanorods developed. Furthermore, partial hydrophobization between ASA LAE/CNCs can be adjusted due to LAE/CNC nanorods, resulting improved stability of ASA-sizing emulsion. This novel shown have small droplet size (0.8 μm), high hydrolysis resistance, degree (300 s) along with remarkable hydrophobicity contact angle 110° long-term storage. work enables realization interfacial self-assembled Pickering-stabilizer, which leads environmentally friendly, pervasive cost-effective emulsification technique next-generation additives.
