A　capacitor-based　circuit　model　is　proposed　to　explain　the　electrochemical　delamination　of　two-dimensional　materials　from　their　native　substrates　where　produced　gas　bubbles　squeeze　into　the　interface.　The　delamination　is　actually　the　electric　breakdown　of　the　capacitor　formed　between　the　solution　and　substrate.　To　facilitate　the　procedure,　the　backside　of　the　ubstrate　has　to　be　shielded　so　that　the　capacitor　breakdown　voltage　can　be　reached.　The　screening　effect　can　be　induced　either　by　nonreactive　ions　around　the　electrode　or,　more　effectively,　by　an　undetachable　insulator.　This　mechanism　serves　as　a　guideline　for　the　surface　science　and　applications　involving　the　bubbling　delamination.
