摘　　要：The interfacial adhesive properties ofpolypropylene/stainless steel were studied by the blister test. The polypropylene film with a squared free-standing window was pressured by oil from one side of film. The corresponding deformation field was observed by a digital speckle correlation method. The experimental results show that the squared film deforms and debonds from stainless steel with the increase of pressure. The debonding of the squared film in initiates from the center of edge and extends to the comer, and then the deformation of film evolves from square to circle shape. The interfacial adhesive energy of polypropylene/stainless steel is （22.60±1.55） J/m2, which is in agreement with that measured by film with a circular window.采用鼓包法研究聚丙烯薄膜/不锈钢基底的粘接性能。基于数字散斑相关法,对自由窗口的聚丙烯薄膜受油压发生变形的全场形貌进行测量。实验结果表明:方形窗口薄膜的剥离最先从四边的中心开始,然后扩展到薄膜的4个尖角,变形形貌从方形最后变成圆形。聚丙烯薄膜/不锈钢基底的界面粘接能为(22.60±1.55)J/m2,这个结果和圆形薄膜窗口测量的结果吻合得较好。
