碩士 / 國立臺灣科技大學 / 材料科學與工程系 / 107 / In this experiment, tetraethoxy decane (TEOS) was reacted in an alkaline environment to synthesize a nano-grade glass film, and the melamine sponge was used as a substrate, followed by dip-coating to make the nano-grade. The glass is coated on the surface of the sponge, and the RF reactive magnetron sputtering system is used to deposit the zirconium-based metallic glass to form a film on the surface of the sponge. Finally, the compression test of the universal stretching machine and the self-made shock absorption test are used for the sputtering. Metallic sponges plated at different times were used to investigate the mechanical properties.
It was found by SEM observation that the cerium oxide synthesized in this experiment was uniformly attached to the surface of the sponge to form a ruthenium film, which changed the thermal stability and surface energy of the substrate. Observing the sponge through the coating, it can be found that the metal glass film is deposited with a thickness of 3 mm of melamine sponge for 2 hours. The sponges were used to observe the sponges with a sputtering time of 2, 4, 6, 8, and 10 hours. The maximum strength and modulus of elasticity corresponding to the fixed spacing were found to be 0.86, 1.02, 1.16, 1.55, 1.64Kg, and 0.103, respectively. 0.12, 0.159, 0.164, 0.176 MPa, all have a high positive correlation. In the shock absorption test, the first rebound height is 3.25, 3.02, 2.69, 2.41, 2.02 cm, which proves that the shock absorption performance has an increasing trend. In addition, the metallic glass film and the metallic filmed sponge were tested under the same conditions. The maximum strength and elastic coefficient of the metal film with a sputtering time of 2, 4, and 6 hours were found to be 0.49. 0.44, 0.42Kgf and 0.068, 0.052, 0.027MPa, the mechanical strength of the sponge coated with the metal film is negatively correlated with the increase of the coating time. In this study, high-strength, high-toughness and low-cost metal glass films were designed on porous polymer sponges. As a cushioning material, it has high development potential in various fields.
