Abstract
Large-area nanopatterningisintroducedona flexible goldsubstratebyblockcopolymer(BCP) lithography.Wefabricateultrahighpowerenergyharvestingnanogeneratorsbasedoncontact- electrification principleexploitingtheeffectivecontactareaenhancementbyblockcopolymer lithography.OwingtothefacileandeffectivesurfaceareaenhancementbyBCPnanopatterning, significantenhancementoftriboelectricchargeinductionisattained.OutputcurrentsfromTENG increased atleast16timesafterBCPnanopatterning.
