摘要: The high hydrophilicity of hemp powder (HP) due to the phenolic hydroxyls limits their application in preparation Pickering emulsions (PEs). For this purpose, study modified surface HP with sodium hydroxide (NaOH) and n-butyl bromide (n-BB) tune its wettability so that it can be used as an effective emulsifier PEs formulations. structure composition were characterized by SEM, EDX, TG, DSC,FTIR TCA. results indicated had been partially converted ethers. By systemically optimized modifiers contents reaction time, balanced amphiphilicity was obtained. Long-term stable homogeneous droplets could successfully fabricated using HP. Moreover, also displayed better sun-screening performance compared unmodified aqueous solutions. This finding broadened potential applications coatings, cosmetic other fields.
