The MWCNT and functionalized (carboxyl and amine) MWCNT concentration varied as 0.25, 0.5 and 0.75 weight percentages. Compositeswere prepared by using a melt compounding method using a twin-screw extruder and all testing samples were prepared using an injection molding machine as per <span style="color:#040c28">American Society for Testing and Materials (</span>ASTM) standards. Samples were tested for tensile strength, impact strength, flexural strength, heat deflection temperature, hardness, and density. There is an increase in the tensile strength, impact strength, flexural strength, and heat deflection temperature, with percentage increase in filler loading up to 0.5 %, followed by decrease in it with higher filler loading. The increase is maximum for amine functionalized MWCNT.</span></span></span></span></span></span><br> <br> &nbsp; ,PAEK,MWCNT,Functionalized MWCNT,characterization,nanocomposites 1 11 http://ijmse.iust.ac.ir/browse.php?a_code=A-10-5165-1&slc_lang=en&sid=1 Pravin Jadhav pnjadhav@git-india.edu.in 1800319475328460017152 1800319475328460017152 Yes 1Department of General Engineering, Institute of Chemical Technology, Mumbai, India2Department of Mechanical Engineering, Gharda Institute of Technology, Lavel, Ratnagiri, India R.S.N Sahai rsn.sahai@ictmumbai.edu.in 1800319475328460017153 1800319475328460017153 No 1Department of General Engineering, Institute of Chemical Technology, Mumbai, India Deepankar Biswas db.biswas@ictmumbai.edu.in 1800319475328460017154 1800319475328460017154 No 1 Department of General Engineering, Institute of Chemical Technology, Mumbai, India Asit Samui samuiasitbaran22@gmail.com 1800319475328460017155 1800319475328460017155 No 1Department of General Engineering, Institute of Chemical Technology, Mumbai, India
