Abstract
In this study, effect of the polyethylene glycol (PEG), temperature and time of curing on
mechanical properties of epoxy resin were optimized using response surface methodology (RSM)
method. With increasing PEG, elongation increased but yield, ultimate strength and Young modulus
decreased. In the next step Ag/CuO (molar ratio: 1/5) nanoparticles (NPs) were synthesized by
ultrasonic route, then was added to optimized epoxy/PEG, which led to significant enhancement of
antibacterial activity and mechanical properties of optimized epoxy/PEG. Comparing yield and
ultimate strength of the epoxy/PEG/(Ag/CuO) with pure epoxy showed amplification of the 70.17%
and 81.41%, respectively. Optimized epoxy/PEG and Ag/CuO nanoparticles were characterized by FT
IR, XRD, SEM, EDX, TGA and DRS.
