WebJan 1, 2024 · The maximum temperature of PMMA is higher than that of copper wire. This is attributed to the thermal conductivity coefficient of copper wire is much higher than that of PMMA. (2) In Fig. 7 (a) and (c), the maximum temperatures of PMMA are respectively 435 K and 468 K when one-core and multi-core copper wire is used. This occurs because the ... WebSep 22, 2024 · The nanoporous wire-coated QTF exhibited higher sensitivity and faster response time than a plain wire-coated QTF, which was attributed to the high surface area and pore networks facilitating the transport of ethanol molecules inside the PMMA wire.
