Effectiveness of Polystyrene/Carbon Nanotube Composite in Electromagnetic Interference Shielding Materials: A Review

Polystyrene is an efficient thermoplastic having fine processability, chemical inertness, and mechanical performance. Technological advances have led to several industrial appliances of polystyrene-based materials ranging from insulation to electromagnetic interference shielding. In this state-of-the-art review, primarily structure and properties of carbon nanotube and polymer/carbon nanotube composite have been discussed. Carbon nanotube is considered as a brilliant filler for polymers. Therefore, a comprehensive discussion regarding high-performance polystyrene/carbon nanotube composite is presented. Main focus of review is the significance of electromagnetic interference shielding phenomenon in polystyrene/carbon nanotube composite. Owing to advantageous properties, these composite have potential to replace traditional shielding materials.
