【 摘 要 】

Pineapple Leaf Fibers (PALF) which is rich in cellulose, relatively inexpensive and abundantly available has the potential for polymer reinforcement. In this study, Polyethylene Terephthalatate (PET) was added with PALF and electro-spinned. The resulting mats were compared with PET neat electrospun. The samples later were examined by Scanning Electron Microscope (SEM), Fourier Transform Infrared (FTIR) and contact angle (CA). Briefly, SEM results indicated that the present of fibers led to a tendency of lower average fiber diameter compared to the PET neat. Two distinct fiber networks with intersecting fibers were observed in PALF/PET. One networks probably corresponds to PET and the others to PALF. FTIR analysis shows the intensity peak represent carbonyl at ∼3400cm-1and ester at ∼1100 cm-1decreased. It is suggested interaction occurred between lone pair of oxygen in the group with hydrogen group in PALF. New peak were observed at 3400 cm-1in PALF/PET that indicated present of hydrogen bonding as well as its hydrophilic tendancy. The contact angle of PET signify high average value 1560that comes with hydrophobic properties compared to PALF/PET with average value 160with more hydrophilic properties.
