Polylactic acid (PLA)/halloysite nanotube (HNT) composite mats: Influence of HNT content and modification

Abstract

Polylactic acid (PLA)/halloysite nanotube (HNT) composite mats: Influence of HNT content and modification, Composites: Part A (2015), doi: http://dx. AbstractPolylactic acid (PLA)/halloysite nanotube (HNT) composite mats were successfully fabricated via electrospinning. Composite mats reinforced by both unmodified and modified HNTs with a dispersant BYK-9076 were prepared at the HNT contents of 0, 1, 5 and 10 wt%/v. The influence of HNT content and modification was investigated comprehensively, based on several characterisation techniques such as scanning electron microscopy (SEM), Xray diffraction (XRD) analysis, mechanical testing, differential scanning calorimetry (DSC), thermogravimetric analysis (TGA) and Fourier transform infrared spectroscopy (FTIR).Typical modified Halpin-Tsai model and modified Halpin-Tsai laminate hybrid model in conventional composite theory were used, which were found difficult to predict the entire experimental data of elastic moduli for PLA/HNT composite mats, possibly arising from the nanosized effect of both HNTs and some electrospun PLA nanofibres within composite mats.

Flammability and thermal properties of polycarbonate /acrylonitrile-butadiene-styrene nanocomposites reinforced with multilayer graphene

“…In particular, plate like GNP in composite mats also tend to be dispersed with a certain level of misalignment and random orientation [22]. Thus a mathematical laminate model [48] to account for the completely disordered GNPs in all three orthogonal directions can be expressed in the following form: properties of polymer nanocomposites with 3D random-oriented nanofillers with the closer formation to real morphological structures [49].

Development of Ethylene-Vinyl Acetate Composites Reinforced with Graphene Platelets

“…With the combination of Equations and (6), a modified Halpin–Tsai laminate hybrid model can be established by using E ∥ = E 11 and E ⊥ = E 22 accordingly. Such laminate hybrid model is very useful to predict mechanical properties of polymer composites with 3D random‐oriented nanofillers with the closer formation to real morphological structures …”

Fabrication and characterization of biodegradable poly(butylene succinate-co-adipate) nanocomposites with halloysite nanotube and organo-montmorillonite as nanofillers

“…To tune the interfacial interactions between HNTs and polymer matrix, chemical or physical approaches have been utilized to modify the surface of HNTs [15e17]. For example, Dong et al [15] prepared and characterized electrospun poly(lactic acid) (PLA) composite mats using unmodified and modified HNTs as the nanofillers. The modification of HNTs significantly enhanced the tensile modulus/strength and thermal stability of the composite mats.…”
