Synthesis, characterisation, thermal and electrical behaviour of copper and copper sulphide-epoxy nanocomposites.

Synthesis, characterisation, thermal and electrical behaviour of copper and copper sulphide-epoxy nanocomposites.

Nanozarah kuprum (Cu) dan kuprum sulfida (CuS) disintesis di dalam fasa akueus dan serta-merta dipindahkan ke fasa organik yang mengandungi epoksi melalui kaedah pemindahan fasa. Spektrum penyerapan UV-vis menunjukkan kehadiran Cu dan CuS. Penambahan diglisidil eter bisfenol A (DGEBA) ke dalam organ...
