| 中文摘要 | in this article a facile way of producing starch-based nanoparticles (snps) with high yields and predictable size by an alkali-freezing treatment is presented. a new mix solvent, sodium hydroxide-urea aqueous solution, has been developed to disperse corn starch. after refreezing, thawing, stirring at room temperature and dialysis, resultant aqueous suspensions of snps are obtained and characterized using a scanning electron microscope (sem) and dynamic light scattering (dls) to learn the particle morphology, mean size and size distribution. by adjusting parameters such as the sodium hydroxide : urea ratio and temperature, the size of particles can be controlled from micro-to nanometer. furthermore, this process that leads to the nanoparticles causes no changes in the structures of the starch granules as characterized by ir or h-1-nmr. freeze-dried snps were found to be amorphous as revealed by wide-angle x-ray diffraction (waxd). |
