Inorganic–Organic Hybrid Materials Based on Amino Acid Modified Hydrotalcites Used as UV-Absorber Fillers for Polybutylene Succinate

Polybutylene succinate (PBS)-functionalized nanocomposites with amino acid tyrosine (TYR)- and tryptophan (TRY)hybrid-interleaved layered double hydroxide (LDH) materials exhibit interesting anti-UV properties and rheological properties. Embedding amino acid into the layered double hydroxide container preserves the UV shielding property of the pristine organic molecule. When employed in an aliphatic polymer such as PBS, chain scission occurs during photoageing and accelerates the degradation of the raw material. However the embedded inorganic amino acid melt blended with PBS prevents such degradative phenomenon. An investigation of their structure–property relationship (i.e.,
