Study of some Structural and Mechaneical porperties of PTFE polymer (UAE)source

Abstract

In this study a pure polytetrafluoroethylene polymer (PTFE) [C2F4]n.
United Arab Emirates (UAE) source prepared from solution cast as film
and strip have been studied by structural (X-ray diffraction (XRD),
Differential Scanning Calorimetry (DSC)) and Mechanical properties,
subjected to different temperature heating cycle. This polymer show
variation in the scattered X-ray intensity of the basal plane (100) as the
temperature of heating cycle is changed and show increasing in
crystallinity with the increase of temperature .Moreover, the enthalpy
increase with the increase of temperature, and show different in mechanical
properties for PTFE (Young's modulus, stress at break, stress at yield,
elongation at yield and elongation at break) when the temperature is change
,The heat treatment of polymer to different temperatures in order to know
its properties and resistance to environmental conditions results showed
that the mechanical properties increase linearly with the increase of
temperature
