摘要: Six novel N-alkyl-N-dimethyl and N-alkyl-N-trimethyl chitosan derivatives were chemically synthesized characterized using FT-IR, 1H NMR, 13C differential scanning calorimetry (DSC), X-ray diffraction spectrometry (XRD). The alkyl groups included octyl (C8H17-), decanyl (C10H21-), lauryl (C12H25-). These also evaluated for their micelle-forming properties dynamic light scattering (DLS) transmission electron microscopy (TEM) techniques. All six capable of forming polymeric micelles in water with an average particle diameter ranging from 36 to 218 nm. Both N-octyl-N-dimethyl N-octyl-N-trimethyl formed nanomicelles under the experimental conditions, 36.0 52.5, respectively. length group N-trimethylation degree altered size micelles. To further understand effect N-alkyl substitution on micelles, additional five 8 58% prepared micelle sizes determined. results showed that was proportional N-octyl substitution. data suggest may form nanomicelles. Additional research is required investigate potential value-added utilization these controlled release targeted delivery hydrophobic bioactive food factors.
