Abstract: |
Micro/nano lignin was prepared by self-assembly method using alkaline lignin as raw material and different surfactant solutions as solvents. The optimal pH value, temperature, and alkaline lignin addition for the preparation of micro/nano lignin under different surfactant solutions were preliminarily discussed. The micro/nano lignin was characterized by nano-particle size and Zeta potential analyzer, scanning electron microscope, and Fourier transform infrared spectroscopy. The results showed that the average particle size of micro/nano lignin prepared by dodecyl sulfate could reach to 94.7 nm. The absorbance and transmittance of the mixture of the prepared micro/nano lignin and commercial face cream were measured by using ultraviolet-visible absorption spectrum, and it was found that the absorbance of the mixture significantly improved, while the transmittance reduced, indicating the mixture was of good ultraviolet protection capability. |
