The multi-nozzle electrospinning is under extensive investigations because it is an easy way to enhance theproductivity and also feasible to produce special structure fibers such as core-shell fibers and to fabricate composite fibers ofthose polymers that cannot form blend solution in common solvent. Control over the multi-nozzle electrospinning fibersdeposition has attracted increasing attentions. The most common method was to use the auxiliary electrode. However, theconcentrated effect of the works of control multi-nozzle electrospinning deposit was inconspicuous. To enhance thecontrolling of multi-nozzle electrospinning deposition, a set-up based oppositely charged electrospinning was designed. Inthis set-up the air flow was used to transport neutralized nanofibers. This electrospinning method was named oppositelycharged and air auxiliary electrospinning (OCAAES). The capacity of OCAAES in deposition area and pattern controllingwere investigated. By the OCAAES, concentrated and several patterned nanofibers deposition were fabricated. Resultsshowed that nanofiber deposition area and pattern of multi-nozzle electrospinning could be controlled actively, and nanofiberdeposition could be fabricated in a quick thickening rate.
