Theoretical and experimental investigation of the wet-spinning process for mechanically strong carbon nanotube fibers

The orientation factor is significantly important for producing highly strong conductive carbon nanotube (CNT) fibers. Highly oriented CNT fibers can be obtained by the wet-spinning of CNTs in a superacid. We present a theoretical model for obtaining well-aligned CNT fibers, which may have superior properties. Our model predicts the minimum draw ratio (DR0) at various Deborah numbers (De) for CNT fibers with the target orientation. In addition,...
