How is it possible to prevent a PTFE membrane blockage while vacuum filtering multiwalled carbon nanotubes?

In functionalizing MWCNTs using HNO3, I used vacuum filtration with a PTFE membrane but in a couple of seconds the solution stopped passing through the membrane and the rate became almost zero. I...
