Multifunctional metallized particleboard for enhanced electromagnetic interference shielding and mechanical thermal stability
The development of multifunctional electromagnetic interference (EMI) shielding materials with low cost, stable performance and mass production is still facing great challenges. High-density traditional metals limit the application of EMI shielding materials. The unique structure of wood is considered an effective way to solve the above-mentioned problems. In this study, waste wood was used as raw material to prepare low-energy metallized particleboard. The particleboard was functionally finished to show excellent hydrophobic properties and been used stably in a humid environment. Dynamic thermal mechanical properties and mechanical properties analyses of particleboard were carried out. The bend strength (MOR), elastic modulus (MOE) and tensile strength were 30.50 MPa, 5384 MPa and 7.85 MPa, respectively. Metallized particleboard exhibited excellent electromagnetic shielding effectiveness (EMI SE) (average value 81.62 dB) in the entire X-band. The preparation of wood-based shielding metallized particleboard provides a feasible strategy for replacing traditional metal materials.
