Abstract
A composite material and methods for making a foldable material are provided. The composite material includes ultra-high molecular weight polyethylene (UHMWPE) and a hard coating material, a portion of the hard coating material being infiltrated into the UHMWPE. The UHMWPE has a highly porous structure of polyethylene and the hard coating material is in a liquid form. The UHMWPE can be formed as a layer on which another portion of the hard coating material is disposed. The layer of UHMWPE has a thickness smaller than 2 μm, a tensile strength greater than 500 MPa, and the composite has a thickness smaller than 5 μm, a tensile strength greater than 100 MPa. And the whole composite is crease free after more than 200,000 cycles of folding.
