Topographically-designed triboelectric nanogenerator via block copolymer self-assembly

Nano Lett. 2014 Dec 10;14(12):7031-8. doi: 10.1021/nl503402c. Epub 2014 Nov 17.


Herein, we report a facile and robust route to nanoscale tunable triboelectric energy harvesters realized by the formation of highly functional and controllable nanostructures via block copolymer (BCP) self-assembly. Our strategy is based on the incorporation of various silica nanostructures derived from the self-assembly of BCPs to enhance the characteristics of triboelectric nanogenerators (TENGs) by modulating the contact-surface area and the frictional force. Our simulation data also confirm that the nanoarchitectured morphologies are effective for triboelectric generation.
