Abstract
Recently, polylactic acid (PLA) has gained attention owing to its advantages,
such as sustainability, eco-friendliness, and biocompatibility. However, PLA has not been
widely utilized because of its low mechanical properties, especially tearing strength. In this
study, halloysite nanotube (HNT) added PLA composite film was prepared through meltblending
to improve the tearing strength. The tensile strength of the PLA/HNT composite
films was enhanced by the filler effect, homogeneous dispersion, and good compatibility
of the HNTs. Moreover, the tearing strength of the PLA composite film significantly
increased from 3.8 to 5.8 N/mm when the HNT was added at 1 wt%.
