Polylactide(PLA) is the completely biodegradable materials
widely used in packaging
textile
biomedical fields
etc. But it has some shortcomings
such as brittleness
the higher price
hydrophobicity
development of PLA is limited. Polylactide blending modification has become a hotspot. According to the biodegradable properties of the other composition in the blends
polylactide blends are divided into two varieties of completely biodegradable blends and partially biodegradable blends.This paper described the research of completely biodegradable polylactide blend system in recent years
mainly introduced PLA/starch
PLA/natural fiber
and briefly introduced the other PLA blending composite materials with natural polymer(PLA/chitin
PLA/protein) and PLA blending composite materials with synthetic polymer(PCL
