Abstract
Poly ether ether ketone (PEEK) is one of the most promising thermoplastics for high performance applications such as biomedical surgical components, seal valves and various components of pump. Chemical and thermal behavior of amorphous PEEK in different chemical environments has been investigated in the present study. Commonly used organic solvents were selected based on Hildebrand solubility parameter for stability analysis of the polymer. Polymeric sheets placed in the solvents for 2 months were analyzed through Fourier Transform Infra-Red (FTIR) Spectroscopy, Thermogravimetric Analysis (TGA) and Differential Scanning Calorimeter (DSC). Chemical structure of the polymer was seen to be altered by toluene, benzene and tetrahydrofuran. The polymer remains resistant to thermal attack after exposure to most of the solvents. Chloroform, THF, toluene and acetone affects stability of the polymer based on the experimental results. Thus, prolonged interaction of PEEK with these solvents requires some additional treatment to make PEEK sustainable in these harsh environments.
