Abstract
A plasticizer, which is biodegradable, has a molecule including a central structure, at least two connecting structures and at least one side-chain structure. The central structure includes at least one of a benzene derivative and at least one amino acid. The connecting structures are respectively connected to the central structure, wherein the connecting structures include a first connecting structure and a second connecting structure. The first connecting structure is an amine group, and the second connecting structure is a carboxyl group. The side-chain structure is a chain of multiple carbon atoms, and the side-chain structure is connected to at least one of the first connecting structure and the second connecting structure. An amide bond is formed as the side-chain structure connected to the amine group, and an ester bond is formed as the side-chain structure connected to the carboxyl group.
