Review on processes of nanofiber prepared by polymer melt method
Abstract:Aiming at the present status of low production efficiency, unstable performance and incapability of realizing large-scale application of nanofibers produced by polymer melt method, the current processes of preparing polymer nanofibers by melt were reviewed. First, current melt preparation methods of nanofiber were classified, compared and analyzed based on the principle of melt method. By combining the present research status, it was suggested that the combination of single nanofiber preparation methods is the development tendency of the preparation of melt nanofiber. Then the relationship between process parameters and fiber fineness was reviewed in detail, and the common problems in melt nanofiber preparation were revealed. In the end, the achievements and main processes of melt differential electrospinning were introduced. The large-scale production of nanofiber with the average diameter below 500 nm is realized by analyzing the mechanics, optimizing the process parameters of melt differential electrospinning technology as well as modifying materials.
Keywords:nanofiber   island in sea spinning   melt electrospinning   melt blowing spinning  centrifugal spinning
