Electrospun poly(lactic acid) (PLA): poly(ε-caprolactone) (PCL)/halloysite nanotube (HNT) composite fibers: Synthesis and characterization
MetadataShow full item record
The incorporation of nanoparticles into polymer nanocomposites via electrospinning offers an effective approach to tailor composite properties and fabricate nonwoven fibrous structures. This chapter describes a general fabrication-characterization route of electrospinning poly(lactic acid) (PLA):poly(ε-caprolactone) (PCL)/halloysite nanotube (HNT) composite fibers. High molecular weight PCL (9 wt%/v and 15 wt%/v)- and PLA (fixed at 8 wt%/v)-blend solutions were prepared with unmodified HNTs and HNTs modified with 3-aminopropyltriethoxysilane. HNTs were also incorporated into PLA:low molecular weight PCL (15 wt%/v) using different solvents (dichloromethane:N, N, dimethylformamide and chloroform:methanol cosolvents) and blend ratios.
