Interfacial Structure Analysis on Direct Bonding Metals to Plastics†

چکیده
This research investigated the direct bonding mechanism of dissimilar materials such as metals and plastic by the conventional hot pressing process. The press area of 4 x 4 mm2 was used for direct bonding. The results of the study showed that titanium was completely bonded to polyamide 66. On the other hand, titanium was not bonded to polystyrene. In the case of bonding material of titanium with polyamide 66, and oxide layer of about 20 nm as reaction layer was confirmed on the bonding interface by transmission electron microscope observation. It was considered that the origin of this oxide layer was due to oxygen constituting amide groups with C=O double bond in the polyamide 66.

Bonding of hydrophobic plastic materials to wood to create new wood-plastic (polystyrene) materials with improved mechanical and physical properties that incorporate the desirable features of each constituent is difficult to achieve, This is due to poor interfacial adhesion between the wood and polystyrene components because of their inherent incompatibility. New, well-defined, tailored cellulo...

The effect of alkyl substituents on the C-phenyl and/or the N-Phenyl ring of benzophenylhydroxamic acid on their molecular structure and hydrogen bonding has been investigated. The predominant configuration in CHCl3 is determined by steric and electronic effects. Substituents on the C-phenyl ring favor the cis configuration, while substituents in the N-phenyl ring favor a trans c...

متن کاملPotential Dependent Alignment and Hydrogen Bonding of Water Molecules at Charged Air/Water and CCl4/Water Interfaces
We observe potential dependent alignment and hydrogen bonding of interfacial water molecules at a charged air/water and CCl4/water interface. The interfacial potential is a result of the presence of charged soluble surfactant adsorbed to the interface. We vary the interface potential by changing the surface charge density, the ionic strength, and the temperature while monitoring OH stretching m...
