Study and optimization of the mechanical properties of PVP/PVA polymer nanocomposite as a low temperature adhesive in nano-joining

Abstract

This paper presents a study of the effects of temperature, curing time and silver nano-particles (AgNPs) on the concentration of the PVP/PVA nano composites on shear force of adhesive nano-joining (ANJ). Low temperature (LT) ANJ of copper-copper (Cu-Cu) at the temperature values of 200, 215, 225, 240 and 275°C and curing times of 10, 20 and 30 minutes, under fixed pressure (5 MPa) are investigated. Higher shear strength value is found at a temperature value of 227 °C and time extent of 10 minutes. It is noted that for an AgNPs concentration of (5%wt) a maximum value of shear strength (2180N) is reached. These results indicate that resistance will increase with raising of the heat up to 227 °C, then followed by a decrease in strength up to 275 °C at a curing time of 10 minutes. The results have been optimized with Neural Network (NN) for accuracy.
