Title

A Study on the Percolation and Deformation Mechanism of Poly(Butadiene Adipate-Co-Terephthalate)-Layered Silicate Nanocomposites

Abstract

Poly(butadiene adipate-co-terephthalate) (PBAT) is a biodegradable polymer that is used in film applications due to its exceptional elongational properties and tear resistance. Nanoclays such as organically-modified layered silicates are used in an increasing number of applications to improve mechanical, thermal and barrier properties of films. When incorporating nanofillers, the optimal percentage must be determined to help improve properties but reduce the cost of the final product. This work aims to study the effects of incorporating a modified MMT clay into PBAT at various clay loading levels and determine how the deformation mechanism of the resulting composite is changed. Viscoelastic measurements, tensile testing, TEM imaging, and XRD patterns are used to study the percolation of nanoclay in PBAT and the formation of a secondary network of nanoparticles.
