Nanofiber membranes are described that include multiple layers of nanofiber structures, where each structure is a composite composition of multiwall carbon nanotubes and one or both of single wall and/or few walled carbon nanotubes. By selecting the relative proportions of multiwall and one or more of single/few wall carbon nanotubes in a nanofiber film, the membrane can be fabricated to withstand the heating that occurs during operation in an EUV lithography machine, while also having enough mechanical integrity to withstand pressure changes of between 1 atmosphere (atm) and 2 atm between operating cycles of an EUV lithography machine.
