**3. Conclusion**

This chapter has included theoretical aspects and applications within a highly interdisciplinary domain: electromagnetic compatibility, plasma physics, textiles, and Life Cycle Assessment. Textile EM shields have been manufactured by two methods – insertion of metallic yarns and plasma coating of metallic layers and their shielding effectiveness has been experimentally determined. In order to assess the environmentally friendly character of plasma coating, a comparative LCA study has been conducted between the woven fabric with conductive yarns and the plasma coated woven fabric. One sqm of shielding fabric with 50 dB at 100 MHz has been considered as a functional unit. Since plasma coating enhances EMSE with 8–10 dB on the frequency domain of 0.1–1000 MHz for the woven fabric with metallic yarns, the grid of the woven fabric with metallic yarns has been reduced in order to reach the same EMSE. Modeling according to relations from the EMC literature has been applied for this purpose. The main challenge of the comparative LCA study has been the relation between additional metallic yarns for the model and the plasma coating of the woven fabric. Since the plasma coating is a laboratory process, the impact on the environment was higher. A business plan has been achieved to implement a scale up plasma equipment for industrial use. Further research is needed to evaluate the eco-friendly character of textile electromagnetic shields.
