โœฆ Synopsis

Abstract

The influence of size and surface area of two different types of clay on the structure and characteristics of PEO/clay nanocomposites in the form of multilayered films is discussed. To search for new synergistic properties and/or improve the properties of nanocomposite films already known, we study polymer nanocomposites that have laponite as well as montmorillonite incorporated. While DSC measurements showed that higher laponite amounts gradually suppress the crystallinity of PEO in the nanocomposite, XRD measurements provided evidence that higher montmorillonite amounts ensure an improved final orientation of the clay platelets, parallel to the plane of the multilayered film.

## Abstract Polymerโ€clay nanocomposites are wellโ€known highโ€performance materials with a superior tensile modulus. However, in the case of composites with polyimide (PI), additional functions require study because PI is a highโ€performance material in itself. Significant enhancement of thermal condu
