Not easy task. You might consider few options.Preliminary cutting and Cold grinding (liquide nitrogen dipping) can be envisaged. I suggest to start with thin nanofiber membrane.
Thanks for your reply Nabyl, I have tried grinding it using mortar while adding liquid Nitrogen but still the fiber membrane is not brittle enough. Do you have any other suggestion for grinding?
I suggest to start another strategy. Nylon 6 is mechanicaly strong, have a look to brittle polymers. If PA6 can't be substituted, try to spin on dynamic waters and proceed with highshear mixing in one step process. You might found short electospun fibers after filtration. Please consider it as hypothesis that can be interesting to investigate. Regards. Nabyl
Can PA6 be degraded with UV radiations, if yes, what should be the wavelength? I am thinking to periodically degrade aligned fibers using a mask followed by sonication is water.
Akash, what kind of nanofibers are we talking about? Are they nanofibers in a non-woven material (electrospun nanofibers), or some sort of fibers confined in a matrix or on a surface?
PA6 is stable regardind UV, depending on molecular weight and humidity/temperature conditions you can expect hydrolysis reaction. Will send you some characteristics within coming days.

Dear Akash,
Please look for a first information on some books or scientific papers to find some helpfully ideas for your study. Bellow are only some selected sources that could be of interest for your R&D subject. On the other hand, it is difficult to assume that you will obtain a uniform fragmentation of PA nanofibers by cryogenic grinding even that this approach is a lot applied in the case of (co)polyamides, mostly to obtain powders. Good luck inn you R&D works and best regards,
Marius
