WebNov 10, 2024 · A thermosetting plastic is a polymer that is irreversibly hardened by heat. Thermosetting plastics are also known as thermosets, thermosetting polymers, or thermosetting resins. The starting material for a thermoset is a liquid or soft solid. Heat provides energy for covalent bond formation, cross-linking the polymer subunits and … WebStill, some polymer materials, for example, polyaniline (PANI) are found to exhibit thermal conducting properties (Conklin et al., 1995). This makes them eligible for nanofluid applications. Water-based nanofluids containing polystyrene nanoparticles are found to exhibit thermal conductivity comparable to that exhibited by nanofluids containing Al 2 O …
