Effect of bubble based degradation on the physical properties of Single Wall Carbon Nanotube/Epoxy Resin composite and new approach in bubbles reduction

In this study the effect of bubble based degradation on the physical and structural properties of Single Wall Carbon Nanotube (SWCNT)/epoxy resin composite samples were investigated and new method based on vacuum shock was presented. For this purpose, with two different methods samples with and without bubble based degradation were fabricated and effect of degradation on the value of electrical conductivity and the amount of Electromagnetic (EM) waves absorption were investigated. Which vacuum shock technique can improve above mentioned properties about 58319.594 and 63.921 percentage for sample without degradation in comparison with destroyed sample due to the bubbles based voids effect. Moreover, the main factors in the bubbles formation and migration during the manufacturing process and their behavior in the matrix with the help of optical and SEM images were examined and their effect on structural properties of composite samples with Micro Raman Spectroscopy was evaluated.
