Carbon nanotube-polytetrafluoroethylene nanocomposite coating for milk fouling reduction in plate heat exchanger

► Wear resistant and self-cleanable nanoparticulate PHE surface. ► Uniformly dispersed MWCNT fillers in PTFE matrix. ► High micro/nanoscale roughness to produce a low surface energy surface. ► Reduction of milk fouling rate and energy consumption of PHEs via CNT-PTFE nanocomposite coating technique. ► Potential coating technique to minimize the CIP downtimes during pasteurization.
