Since polymer material is widely used for several engineering applications where low weight is a primary requirement, it becomes imperative that they possess high mechanical strength. In this experimental work we have been able to successfully fabricate the composites of LDPE with high strength MWCNT using simple solvent mixing method. Various characterisation techniques like SEM and RAMAN spectroscopy confirm presence and uniform dispersion of MWCNT in LDPE, thereby enabling these composites to be used for various other mechanical and electrical testing techniques. It is expected that MWCNT will be able to impart sufficient strength to LDPE polymers as well to be used for various other applications
