a The d33 results measured using d33 meter. (The error range is based on 30 independent samples.) b Strain induced by an electric field at 1 Hz whereas the slope is indicative of d33 via the converse piezoelectric effect. c g33 and d33×g33 as function of NaOH dosage. (The error range is based on 30 independent samples.) d Comparison of d33. e Comparison of g33. f Comparison of d33×g33. Non-oriented data were taken from ref. 15 and uniaxially oriented data were taken from ref. 17. Error bars in a and c represent the standard deviation of the mean obtained from at least three measurements using different samples. Error bars in a and c represent standard deviations obtained from five measurements using different samples.
