1. A method for large area production of CVD-processed materials, the method comprising the steps of:
- a) positioning a first remounted substrate roll into the primary reaction chamber of a batch process chemical vapor deposition synthesis system, said roll being formed of i) an extended first substrate having a width W, a length L and a thickness T, wherein T<
<
W<
<
L, and ii) at least two outer spacer strips, and wherein said first substrate is wound in its length direction in such a manner that said outer spacer strips are inserted between each consecutive layer of said roll and located near the edges of said width of said substrate;
b) processing said roll via chemical vapor deposition, said outer spacer strips being formed of a material which is substantially open thus permitting substantially uninhibited process gas exchange between the internal and external volume of said roll; and
c) removing said roll from said process chamber after completion of said chemical vapor deposition process.

Abstract
The present invention relates to tools and system designs for chemical vapor deposition (CVD) systems and CVD synthesis used to deposit one or more thin film layers onto a flexible substrate or to grow nano-structured materials on large area flexible substrates and, more particularly, to scalable CVD coating and nanostructure manufacturing including CVD thin films and nano-structured materials such as nanotubes, nanowires and nanosheets.

20. A remounted substrate roll, comprising:
-
a rolled-up flexible substrate forming an Archimedes spiral and defining a plurality of consecutive layers, said substrate having at least one catalytically-active surface and defining a width W, a length L and a thickness T, wherein T<
