Nanofiber Membranes

Cellulose acetate (CA) nanofiber membranes incorporated with diatomite (DE) were prepared by electrospinning to produce electrospun nanofiber membranes with high specific surface area and high porosity with fine pores. When the DE percentage increased from 0 to 30%, the water contact angle (WCA) of the membranes increased from 86.21° to 118.44°, indicating that neat CA nanofibers were more hydrophilic than CA/DE nanofibers and had a better wetting tendency. CA, CA-10DE, and CA-20DE nanofiber membranes showed a mean flow pore size (MFP) of 2.941, 2.681, and 2.408 μm, respectively, with narrow pore size distributions. However, the CA-30DE nanofiber membrane showed a smaller MFP size of 0.5014 μm. CA nanofibers were produced in the range of 206.31 to 281.13 nm. The dye removal ability of these membranes was tested using an aqueous solution of C.I. Reactive Red 141.

Mesoporous materials have typical average pore diameters in the range 20 – 500 Å, which are usually accompanied by high specific surface area (ABET) and large pore volume (Vp) with narrow pore size distributions. These features are very attractive for potential application as catalysts and adsorbents. Mesoporous materials are usually prepared by soft templating or nanocasting process. The latter approach is based on the replication of hard-templates, such as mesoporous silica (e.g. SBA-15), being a very flexible and suitable method to obtain stable and predictable pore mesostructures. However, the chemical compatibility between the template and the precursors must be ensured.
