Which kind of crystallinity you are taking? PANI (whatever it is?), or PANI and filler, or only filler? Is there and treatment? Is your question speculative or do you have experimental data which you could show?
Please....explain abbreviations before using. Only because you are using them daily it does not mean that they are commonly known.
multi wall carbon nano tubes (MWCNT) have a hexagonal crystal structure hence with increment of their amount in your composite the crystallinity of composite must be increased.
we are exactly working on make PANI/MWCNT composite by sol-gel method.
