Abstract (en)
[origin: WO2022122774A1] The invention relates to a laser-assisted adhesive tape and a sealing structure comprising the adhesive tape. Specifically, under the action of a laser, the adhesive tape can be foamed and expanded directionally and quantitatively to fill the gaps between the components adhered by the adhesive tape. The adhesive tape is particularly suitable for filling irregular gaps.
