Fabrication of Composite Nanofibre PEO/Lignin for Exhaust Gas Emissions by Electrospinning

: Air pollution from the combustion of exhaust gas emissions increases with the rise in motorized vehicles use which affects human health. Therefore, it is important to control gas emissions from motorized vehicles. In this study, electrospinning was used to fabricate composite nanofibre lignin/PEO as a filter for gas emission. The nanofibers obtained were analyzed by using SEM before and after gas emission test. The morphological analysis showed that the presence of lignin in the PEO decreased the diameter of the nanofibre from 800 nm to 100 nm, hence improved the gas adsorption efficiency. After gas emission test, the filtration power was 61% for hydrocarbon gas, 81% for CO gas, and 33% for CO 2 gas.
