Correction: Wood-based cellulose nanofiber membrane: a novel approach to high-performance air filters

Air filters are intended to effectively remove particles in the air, and their structure is built of ordinary micro fibrilated cellulose (MFC). Fibrous membrane (FM) was developed using cellulose nanofibers (CNFs) and carbon nanoparticles (CNPs) with different concentrations (0.5, 1.0, and 1.5 wt%) by electrospinning process offer high-performance air filters than those produced of normal MCF due to their larger surface area and smaller pore size. In this study, dust removal effectiveness proved that introducing a membrane containing 1.5 wt% of CNPs significantly improved air filtration while simultaneously increasing pressure drop. The FM had favorable results of the tensile strength (26.48 ± 0.41 MPa), elongation at break (19.23 ± 0.13%), water absorption (28.14 ± 0.22%) and desorption (30.14 ± 0.13%). The findings showed that FM offered 99.99% filtration efficiency, indicating an acceptable technique for constructing inexpensive basis-weight HEPA filters using using CNFs and CNPs as the primary filtration material.
