Hello folks
I'm looking for the artice which shows difference of hierarchical structures between membranes and nanofibers.
From introduction, I remember it kinda said: hierarchical membranes are layered from micropores(filter part) to macropores(support) so fluid slows down when passing the membranes, while hierarchical nanofibers consist of random sized pores so fluid does not slow down as much as membranes.
I'm not sure the materials are preceramic polymers or ceramics or neither, but I'm sure I saw the article.
Anybody know?
