In this study, natural agarose and agar polysaccharides were successfully developed to novel fibrous form for the first time via wet-spinning. Dimethyl sulfoxide (DMSO)/H 2 O=9:1(v/v) mixture was used as an appropriate solvent which was amenable to the wet-spinning process that produced continuous agarose and agar fibers in ethanol coagulation bath. Results of SEM investigation, swelling ratio...
A novel method is developed for grafting carbon nanotubes (CNTs) onto the carbon fiber (CF) surface by use of dendrimers. CF surface is functionalized by an adsorbed dendrimers layer. After an oxidation treatment, CNTs with carboxyl, carbonyl or hydroxyl groups are grafted onto the amino-functionalized CFs via chemical interactions. Homogeneous multi-scale structures with different CNT densities and...
