چکیده مقاله
In order to prolong the shelf life of perishable food during transfer, biodegradable packaging materials must have a lower thermal conductivity This will improve consumer safety and lower postharvest losses Hence, this study uses cellulose acetate CA , the low thermal conductive biodegradable polymer, and multi walled carbon nanotubes MWCNTs , an ultra reducing thermal conductivity adding, to produce the CA/MWCNT composite nanofibrous media via electrospinning technique with oxygen enriched method Therefore, two separate solutions of CA and CA/MWCNT solutions were made by acetone/ dimethylacetamide 2:1 with the oxygen enriched method by an oxygen capsule The morphology and chemical structures of nanofibers were screened by SEM and FTIR Eventually, the thermal conductivity of electrospun nanofibrous media was calculated by the two plate Togmeter device test method based on BS 4745:2005 According to SEM images, by oxygen enriched method with an oxygen capsule, the intensity reaction between CA and MWCNTs was substantial because of whole covered CA nanofibers by MWCNTs, and its media was exploited to compute the thermal conductivity of CA/MWCNT Moreover, the outcomes showed that the thermal conductivity of the CA/MWCNTs sheet was at 0 015 𝑊𝑚 K⁄ with 0 157± 0 083 mm thickness Therefore, CA/MWCNTs nanocomposite media has excellent potential to be applied as ultra low thermal electrospun media to preserve food warmth in food packaging
