Abstract
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 organosol masing-masing dan setelah penyingkiran pelarut memberikan nanokomposit Cu- dan CuS-epoksi. Komposit ini dimatangkan menggunakan 4,4’-metilenadianilina (MDA).
Copper (Cu) and copper sulphide (CuS) nanoparticles were synthesised in an aqueous phase and subsequently transferred into the organic phase containing epoxy via phase transfer technique. The UV-vis absorption spectra confirmed the existence of Cu and CuS. Incorporation of diglycidyl ether of bisphenol A (DGEBA) into the respective organosols and upon solvent removal afforded Cu- and CuS-epoxy nanocomposites. These composites were cured using 4,4’-methyelene-dianiline (MDA).
