AB  - Regulated triboelectrification has attracted considerable research attention due 
      to its potential applications in harvesting energy and importance in antistatic 
      protection. Irradiation is an effective and stable modification method due to its 
      adjustable and uniform irradiation parameters. Moreover, atomic oxygen (AO) 
      irradiation is an important component in the low earth orbit, which is a 
      considerable factor for promoting triboelectric nanogenerators (TENGs) in the 
      outer space. AO irradiation was utilized to manipulate the surface structure and 
      chemical composition to regulate electrical properties. AO irradiation can 
      increase electron-donating groups and enhance electrical positivity of 
      polydimethylsiloxane (PDMS) films due to the transition from Si-C bonds to Si-O 
      bonds. Therefore, different trends of polytetrafluoroethylene (PTFE) and 
      polystyrene (PS) were caused by their TENG composition with irradiated PDMS. 
      Tribocharge cross-over polarity and charge generation were prevented completely 
      in PS- and PDMS-based TENGs by adjusting the irradiation time to 4.1 h. 
      Short-circuit current enhanced from 5 to 22 muA and the output voltage increased 
      from 160 to 760 V when PDMS films in PTFE- and PDMS-based TENGs were subjected to 
      AO irradiation for 6 h. This study demonstrated that AO irradiation can 
      manipulate triboelectric properties of silica-based materials, which are 
      potential components for harvesting energy and preventing electrostatic hazard in 
      the outer space.
