Research Status of Application and Process Optimization of Intense Pulsed Light Sintering of Nanoparticle-ink
Intense pulsed light(IPL)sintering technology or flash light sintering,has attracted extensive attention due to its advantages of fast,selective,non-contact and easily integrated with roll-to-roll equipment.The application and research status of IPL sintering nanoparticle-ink in the fields of printed electronics,solar cells,additive manufacturing and functional device fabrication were reviewed.The failure phenomenon such as bulging,cracks,debonding and warpage of the sintered films during IPL sintering and its reasons for failures were introduced.Three types of effective process optimizing methods named two-step flash light sintering,multi-pulsed flash light sintering and multi-cycle intense pulsed light sintering and their application were introduced.It was proposed that the basic mechanistic research was urgently needed,which can theoretically guide the optimization of IPL sintering process.
