چکیده انگلیسی
Piezoelectric energy harvesting technology has received much attention as a powerful source of energy for a self-powered system. In this study, three main conjugated polymers that have delocalized Ï-electrons and excellent charge transport properties were studied: poly(3-hexylthiophene) (P1), poly[(4,8-di-(2-ethylhexyloxy)benzo[1,2-b:4,5-bâ²]dithiophene-2,6-diyl)-alt-(5,5â²-yl-4,4â²-bis(dodecyl)-2,2â²-bithiophene)] (P2) and poly[(4,8-di-(2-ethylhexyloxy)benzo[1,2-b:4,5-bâ²]dithiophene-2,6-diyl)-alt-(5,5â²-yl-4,4â²-bis(2-ethylhexyl)-2,2â²-bithiophene)] (P3). Each of three polymers was blended with phenyl-C61-butyric acid methyl ester (PCBM61), and the blend systems were used to make PVDF based piezoelectric nanogenerators (PNG-0-3). Polymers showed bimodal structures that have a majority edge-on orientation, forming a minority face-on orientation. At a 2Â Hz frequency and 0.2Â mm displacement, the output voltages (peak-to-peak) of PNG-(0-3) were 35.0Â V, 41.2Â V, 42.2Â V and 43.1Â V, respectively, and the output currents (peak-to-peak) were 558.5Â nA, 569.5Â nA, 572Â nA and 589Â nA, respectively. The energy conversion efficiencies of PNGs (0-3) were 6.47%, 11.62%, 13.36%, and 14.33%, respectively; therefore, the efficiency was improved by up to about 2.2 times.
