Thermal and anti‐corrosion analysis of nano‐porous phenolic‐novolac‐Zn composite materials

The phenolic‐novolac‐Zinc composite materials with hexamethylenetramine (HMTA) 8 wt% at Zinc powder content weight from 2% to 11% are investigated by Scanning Electron Microscope, Differential Scanning Calorimetry, Thermogravimetric analysis, and Kissinger method. It is found that a nano‐porous structure is synthesized in phenolic‐novolac porous with 8 wt% HMTA and 5 wt% Zn powder. The thermal and anti‐corrosion analysis shows that the composite with nano‐pores structure produces the highest glass‐transtion temperature, decomposition temperature, and the best anti‐corrosion property comparing with other samples. Furthermore, it introduces a novel method to prepare the nano‐porous phenolic‐novolac‐Zn composite material which can be used as the functional material. POLYM.
