Nanoporous coatings have beco
me the subject of intense investigation, in part because they have been shown to have unique and tailorable physical properties that can depart greatly fro
m their dense or
macroscopic counterparts. Nanoporous coatings are frequently fabricated utilizing oblique-angle or glancing-angle physical vapor-phase deposition techniques. However, a significant li
mitation for such coatings exists; they are al
most always deposited on s
mooth and rigid planar substrates, such as silicon and glass. This li
mitation greatly constrains the applicability, tailorability, functionality and even the econo
mic viability, of such nanoporous coatings. Here, we report our findings on nanoporous/poly
mer co
mposite syste
ms (NPCS) fabricated by utilizing oblique-angle electron-bea
m methodology. These unique co
mposite syste
ms exhibit several favorable characteristics, na
mely, (i) fine-tuned control over coating nanoporosity and thickness, (ii) excellent adhesion between the nanoporous coating and poly
mer substrate, (iii) the ability to withstand significant and repeated bending, and (iv) the ability to be
molded confor
mably on two and three-di
mensional surfaces while closely retaining the co
mposite syste
m鈥檚 designed nanoporous fil
m structure and, hence, properties.
