- 摘要：
- Many stretchable electronic devices require
stretchable hermetic seals. However, stretchability and
permeability are inextricably linked at the molecular level:
stretchable, low-permeability materials do not exist. We
collect data for the permeation of water and oxygen in
many materials and describe the scaling relations for both flat
and wrinkled seals. Whereas flat seals struggle to fulfill the
simultaneous requirements of stretchability, low stiffness, and
low transmissibility, wrinkled seals can fulfill them readily. We
further explore the behavior of wrinkled seals under cyclic stretch using aluminum, polyethylene, and silica films on elastomer
substrates. The wrinkled aluminum develops fatigue cracks after a small number of cycles, but the wrinkled polyethylene and
silica maintain low transmissibility after 10 000 cycles of tensile strain.
