Preparation and Performance Study of Polybutylene Succinate/Esterified Modified Luteolin Composite Materials
2024
Overview
To improve the performance of biodegradable materials and endow them with functionality, luteolin (Lc) was modified by esterification with acetyl chloride (Ac), iso butyryl chloride (Ic), benzoyl chloride (Bc) to improve its hydrophilicity and hydrophobicity, and Ac-L, Ic-L and Bc-L esters were obtained. The three esterified compounds were characterized and blended with PBS to prepare PBS/Ac-L, PBS/Ic-L and PBS/Bc-L composites. Studied the interface interaction mechanism, crystallization performance, thermodynamic performance, hydrophilic properties, and antibacterial performance between composite materials. The results showed that the majority of Ac-L, Ic-L, and Bc-L were dispersed in the PBS matrix, with a tighter two-phase interface and higher dispersibility. There were electrostatic adsorption, hydrogen bond and other interactions in the composite system, and the Intermolecular force became stronger and the compatibility increased. The introduction of Ac-L, Ic-L, and Bc-L did not change the crystal structure of PBS, but the crystallization rate and crystallinity of the composite material increased. The thermal decomposition temperature of composite materials increased, and the thermal stability and mechanical properties were further enhanced. With the increase of the amount of Ac-L, Ic-L, and Bc-L added, the antibacterial and hydrophobic properties gradually enhanced, making it suitable for use as a preservation and antibacterial material.
