Smart composite nanofibers based on PLA/PEG with the addition of clove oil as thermal regulators

Smart nanofibers based on PLA and PEG with the addition of clove oil (Eugenia caryophyllus) (EO) were obtained using the electrospinning technique. The nanofibers were characterized by SEM, FT-IR, TGA and DSC. For the PLA/PEG/EO composite (mass ratio 2/1/0.25), the temperature of the maximum decomposition rate was approximately 370 degrees C. This composite exhibited good latent heat energy storage (melting enthalpy 77.5 J/g at 34.7 degrees C). Smart nanofibers can be used as thermal regulators in medicine, electronics, and food and textile industries.
