In this work we focused our attention on an innovative use of food residual biomasses. In particular, we produced biochar from coffee waste and used it as filler in epoxy resin composites with the aim to increase their electrical properties. Electrical conductivity was studied for the biochar and biochar-based composite in function of pressure applied. The results obtained were compared with carbon black and carbon black composites. We demonstrated that, even if the coffee biochar had less conductivity compared with carbon black in powder form, it created composites with better conductivity in comparison with carbon black composites. In addition, composite mechanical properties were tested and they generally improved with respect to neat epoxy resin.

Electromagnetic Shielding Effectiveness

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.

Electromagnetic Shielding Effectiveness

A new kind of the electromagnetic shielding composite coatings with high performance was prepared using the Ni-Cu-coated glass fibers and nickel powders as fillers and using epoxy resin as binder. The effects of the fibers on the conductivity and electromagnetic shielding effectiveness of the coatings were studied. The study results show as follows: 1) when the optimum ratio of the fillers to epoxy resin is 4:1, the coatings containing 6 wt% the Ni-Cu-coated glass fibers has best conductivity and electromagnetic shielding effectiveness; when the coating layer thickness is 300 μm, the shielding effectiveness of the coatings is up to 43.71-52.31 dB and increased an average of 13.94 dB compared with the nickel powders/ epoxy resin electromagnetic shielding coatings in the frequency range of 0.3-1000 MHz. This offers a new idea to enhance the added value of the glass fibers and the prevention of electromagnetic environmental pollution.
