TL;DR
Scientists made new eco-friendly surfactants from glucose that work well on various materials and could be used in cleaning products and coatings.
Contribution
Novel glucosylamide organosilicon quaternary ammonium salts with low surface tension and long-lasting material modification properties are synthesized.
Findings
Surface tension was reduced to 33.4 mN/m for 2SiDDGPBH and 33.64 mN/m for 3SiDDGPBH.
3SiDDGPBH-treated MFR plywood maintained spreading performance after 80 washing cycles.
SEM analysis showed increased silicon content and improved bonding properties in treated materials.
Abstract
Using renewable D-gluconic acid δ-lactone as the starting material, two novel glucosamide-based organosilicon quaternary ammonium surfactants (2/3SiDDGPBH) were synthesized through an environmentally friendly three-step process involving amidation, hydrophobic modification, and quaternization. Comprehensive characterization demonstrated their exceptional performance: surface tension reduction to 33.4 mN/m (2SiDDGPBH) and 33.64 mN/m (3SiDDGPBH), uniform spherical micelles (1–10 nm and 30–100 nm) were formed, and outstanding foam properties with 3SiDDGPBH developed, showing superior foamability and stability. Material modification tests on polymethyl methacrylate (PMMA) plates, mature acacia leaves, oilpaper, vegetable-tanned top-grain leather, and melamine-formaldehyde resin (MFR) faced with plywood revealed excellent spreading performance and durability, particularly for…
