The efficiency of sorption is excellent. Nowadays, various pollutions are increasingly serious, and the demand of activated carbon of high performance is also increasing. If activated carbon could be made as ultrafine fibrous structure, in addition to surface adsorption, the net structure formed by fibers could also block microparticles. Comparing to power- or particle-like activated carbon material, activated carbon fiber would have potentials to develop more applications. Moreover, using technical lignin as precursor to produce carbon fiber has been studied. The lignin fibers with small diameters and big surface area could be made with electrospinning technology, and then activated and carbonized, which may be a potential application on filtration about protection and control from nanoparticles. In this study, electrospinng technology will be used to develop lignin activated carbon nanofibers, and various properties about efficiency of filtration will be evaluated. The goal is to develop value-added lignin products as advanced filtration materials.奈米活性碳纖維濾材靜電紡絲activated nano carbon fiberfiltrationelectrospinning
