Abstract

As one of the most promising bio-based and biodegradable polymers for industrialization

supercritical fluid foaming technology using poly(lactic acid) (PLA) has emerged as a key pathway for achieving lightweight and functional applications. Recent research progress on supercritical fluid (primarily supercritical CO

scCO

) foamed PLA materials is systematically reviewed

with focus on three core directions: bulk modification strategies

formulation compounding technologies

and foaming process innovations. By summar

izing representative research findings and integrating the current application status of foamed PLA

this review analyzes the existing technical bottlenecks and outlines future development trends

providing theoretical support and practical guidance for the development of high-performance biodegradable foam materials.
