  • Patent number: 10305021
    Abstract: Disclosed is a piezoelectric material including stereocomplex crystals of poly(D-lactic acid) (PDLA) and poly(L-lactic acid) (PLLA), wherein poly(D-lactic acid) and poly(L-lactic acid) are crystallized into a stereocomplex, thus exhibiting superior heat resistance and piezoelectric properties. This piezoelectric material, which is obtained using poly(lactic acid), can be produced at very low cost compared to when using PVDF, and is configured to include stereocomplex crystals of PDLA and PLLA and can thus manifest high thermal stability and piezoelectric properties, compared to when using conventional PLLA alone. Such a piezoelectric material can be efficiently utilized in a variety of fields in which low production cost, high processing temperature in the manufacturing process, or high-temperature stability of piezoelectric material products is required.
