1. Preparation
Polyaryletherketones (PAEKs) are a family of semi-crystalline thermoplastics based on highly stable phenyl compounds.
1.1 Structure of polyaryletherketones
PAEKs consist of aromatic rings joined by an oxygen atom (ether) and/or a carbonyl group (ketone) (figure 1).
The properties of different PAEKs depend on their molecular structure and degree of crystallinity. Molecular structure influences thermal properties, resistance to beta, gamma and X-rays, and fire resistance. The glass transition temperature (Tg ), melting temperature (Tf ), thermal resistance and processing temperature depend on the number of ether/ketone units (figure
