Abstract
- A novel chitosan derivative carrying the benzene group was synthesized by Michael reaction. The chemical structures of the compounds were characterized by FT-IR, UV-vis spectrometry, XRD, elemental analysis, and 1H NMR spectroscopy in detail. The degree of substitution (DS) of chitosan derivative was calculated by elemental analysis. The UV-vis results indicated that the derivatives had ultraviolet absorption at 265 and 273 nm. XRD analysis showed that the derivatives were amorphous. The derivatives could dissolve in water. Taking advantage of the known capacity of solubility and ultraviolet absorption, the chitosan derivatives opened new possibilities for use as a sunscreen.<br /> (Copyright 2010.
