Tuning the surface chem. of nanocellulose is essential for developing its end-use applications. Herein, different carboxyalkylated cellulose nanocrystals (CNC) with similar charge densities but with tunable hairy structures were produced. The effect of carbon spacer of the grafted groups on the interaction of the CNC and a cationic surfactant, myristyl tri-Me ammonium bromide (MTAB), at different pH and salinity was explored. The CNC with longer grafted chain length was more hydrophobic, adsorbed more MTAB, and formed a more compact MTAB ad-layer than did CNC with the shorter chain length. Also, the adsorption was higher at neutral pH, implying a high electrostatic attraction and hydrophobic interaction between substrates. The hydrophobic interaction of MTAB and hairy CNC in saline systems improved its adsorption. Although MTAB adsorbed more when its concentration was higher than its critical micelle concentration (CMC), the adsorbed ad-layer had a less compact structure on the CNC surfaces. The experimental part of the paper was very detailed, including the reaction process of 8-Bromooctanoic acid(cas: 17696-11-6Quality Control of 8-Bromooctanoic acid)
8-Bromooctanoic acid(cas: 17696-11-6) acid is used in the synthesis of 8-(N-Methyl-4,4′-bipyridinyl)- octanoic acid. 8-Mercaptooctanoic acid was prepared from 8-bromooctanoic acid. And 8-Bromooctanoic Acid is a useful compound for sonodynamic therapy.Quality Control of 8-Bromooctanoic acid
