Shape memory polymer (SMP) and self?healing polymer (SHP) as the representative of "smart" polymers have become the most dynamic research direction in this field,among which photosensitive SMP and SHP have been received wide attentions by industry and academia.This paper reviews the basic principles of photosensitive SMP and SHP, and classifies this type of polymers into reversible photochemical reaction SMP,photothermal SMP,photodimerization reaction SHP,photocrosslinking reaction SHP,and bifunctional SMP/SHP by referencing the most important and representative literature reports in recent years.
