Preliminary Study of Polypropylene/Coir/Carbon Black Conductive Wood Plastic Composite

Abstract

Our living environment is full of diverse electronic products, making conductive polymer a popular subject for researchers. Insulating polypropylene (PP) can be improved in terms of conductivity by intermingling with electroconductive materials. Carbon black and carbon fiber are two materials that can supplement electroconductive and mechanical properties in insulating polymer materials. In this study, natural coir is first alkali-treated and then melt-blended with PP and carbon black, forming the composite. The resulting composite is tested in terms of its electromagnetic shielding effectiveness and mechanical properties. According to the results, when the amount of carbon black is 12 wt% and coir 3 wt%, the composite displays the optimum electromagnetic shielding of -23.56 dB, tensile strength of 37.07 MPa, and flexural strength of 47.21 MPa.

Medium density fiberboard (MDF) with efficient electromagnetic shielding: Preparation and evaluation

“…Increased human awareness and technological progress have created a need for more sustainable technologies and products. So, much research has been focused on the development of green and sustainable products that are comprised of natural fibers (Li et al 2010;Lou et al 2012). As such, the development of electromagnetic shielding materials from sustainable and environmentally friendly resources has become an important issue for researchers in composite industries.…”
