Abstract:Polymer-based barrier materials are crucial for several
applications,
from food packaging to electronics sealing. However, the inferior
intrinsic barrier performance greatly restricts their applications,
which is urgently necessary for further enhancement. In this work,
we proposed a strategy named modified dynamic pressure engineering
to regulate the nature of crystalline and amorphous regions of semicrystalline
polyethylene terephthalate for enhancing its barrier performance.
