Macromolecular piezoelectric material and manufacturing method therefor |
| abstract |
There is provided a polymeric piezoelectric material including a helical chiral polymer (A) having a weight-average molecular weight of from 50,000 to 1,000,000 and an optical purity of more than 97.0%ee but less than 99.8%ee as calculated by the following formula, in which a piezoelectric constant d 14 measured at 25°C by a stress-charge method is 1pC/N or more: optical purity % ee = 100 × L − form amount − D − form amount / L − form amount + D − form amount , [in which an amount of L-form (% by mass) and an amount of D-form of an optically active polymer (% by mass) are values obtained by a method using high-performance liquid chromatography (HPLC)]. |
