Production of Dynamic Thermal Insulators By Coaxial Electrospinning of PAN and PEG
MetadataShow full item record
In the present work, we produced bicomponent nanofibers, composed of polyacrylonitrile (PAN) shells and PEG cores (PEG2000 and PEG4000), by co-axial electrospinning as new thermal energy storage materials that are suitable for further industrial uses. SEM images showed that the nanowebs of PAN-PEG shell-core nanofibers with smooth surfaces and of the average diameters smaller than 460 nm were successfully produced. The heat absorbed by PAN-PEG2000 nanoweb is 100.3 J/g between 50.6-56.5 C and of PAN-PEG4000 is 144.6 J/g between 54.0-60.7 C, which are quite remarkable in terms of their contribution to the dynamic thermal management of various textile products.
