Preparation of high performance composites based on aluminum nitride/poly(ether–ether–ketone) and their properties

摘要: Abstract Novel high performance aluminum nitride (AlN)/poly(ether–ether–ketone) (PEEK) composites containing 0–50 wt.% fractions of AlN were prepared by solution blending method followed hot pressing to evaluate their density, melting temperature, crystallization, thermal stability, morphological behavior and Vickers hardness using different characterization techniques. Differential scanning calorimetry results indicated that the particles are very effective nucleating agent, which in increase point, crystallization temperature crystallinity as content increases. Thermogravimetric analysis showed enhanced stability with respect PEEK. Density X-ray diffraction techniques increases wt.% polymer matrix. Scanning electron microscopy revealed well dispersed no porosity composites. samples increased from 24 kg/mm 2 for pure PEEK 35 kg/mm AlN/PEEK
