The potential of thermally conductive polymer composites regarding crystallization fouling mitigation

چکیده
Abstract The fouling kinetics and amount of calcium sulfate carbonate, respectively, on different polypropylene/graphite composites in a flat plate heat exchanger are determined compared to the reference material stainless-steel. For straight evaluation susceptibility materials formation bubbles is considered by optical imaging or excluded degasser. results interpreted using surface free energy roughness surfaces. show that when bubble avoided, polymer have very low tendency stainless steel. This particularly case turbulent flows present sandblasted specimen used. Sandblasting also continues increase transfer untreated samples increasing thermal conductivity creating local turbulences. Depending test conditions, resistance formed stainless-steel an order magnitude greater than composites. In addition, layers adhere only weakly composites, which indicates easy cleaning place after deposits.

In Situ Alloying of Thermally Conductive Polymer Composites by Combining Liquid and Solid Metal Microadditives.
Room-temperature liquid metals (LMs) are attractive candidates for thermal interface materials (TIMs) because of their moderately high thermal conductivity and liquid nature, which allow them to conform well to mating surfaces with little thermal resistance. However, gallium-based LMs may be of concern due to the gallium-driven degradation of many metal microelectronic components. We present a ...

The directed self-assembly of gold nanoparticles through the crystallization of surface-grafted polyethylene oxide (PEO) in ethanol-water mixtures is described. This process is fully reversible and tunable through either the size of the core or the polymeric coating. Characterization by X-ray scattering and electron microscopy of the self-assembled structures reveals order at the nanoscale, typ...
