- Large-area nanopatterningisintroducedona flexible goldsubstratebyblockcopolymer(BCP) lithography.Wefabricateultrahighpowerenergyharvestingnanogeneratorsbasedoncontact- electrification principleexploitingtheeffectivecontactareaenhancementbyblockcopolymer lithography.OwingtothefacileandeffectivesurfaceareaenhancementbyBCPnanopatterning, significantenhancementoftriboelectricchargeinductionisattained.OutputcurrentsfromTENG increased atleast16timesafterBCPnanopatterning. Thisnanogeneratorcangenerateremarkably high outputvoltageandcurrent,whichcandirectly lightup504seriallyconnectedLEDs.The resultant nanogeneratorattainsthemaximuminstantaneouscurrentof1.6mAandoutputpowerof 93.2 W/m2.
