Theoretically,
defect-free monolayer graphene grown by
chemical
vapor deposition can block nearly all gases and moisture, making it
a promising material for large-scale flexible encapsulation in future
photonic and electronic applications. However, the lack of reliable
transfer and fabrication methods that suppress the formation of transfer-induced
cracks and interlayer transport of water molecules in stacked graphene
films severely limits the barrier performance of current graphene-based
barrier films. In this work, we employed a dopant-incorporated polyvinylidene
difluoride with a concentration gradient as a transfer medium to suppress
crack formation during transfer through conformal graphene–polymer
contact and to dope graphene, thereby hindering water diffusion through
enhanced water–graphene interactions. Consequently, the as-fabricated
barrier film achieved an ultralow water vapor transmission rate value
of 9.3 × 10<sup>–5</sup> g m<sup>–2</sup> day<sup>–1</sup>. In addition, a home-built roll-to-roll transfer
system for continuous fabrication of graphene barrier films demonstrates
the scalability of this strategy and its potential for large-scale
flexible and transparent encapsulation.
