Bonding Between Polymers and Metal by Coupling Agents

Coupling agents (silanes and piperidines) are deposited from the vapor phase on a polymer sheet, while the temperature of the polymer is maintained between the melting point and the glass transition temperature.

After the coupling agents are deposited, the polymer sheet is exposed to moist air for hydrolysis. This structure is used for bonding two metal sheets. The polymer layer containing the coupling agents is sandwiched between the two metal parts, as shown in the drawing, under pressure and at a temperature that is higher than the melting point of the polymer, to form an improved bond between the two metal parts.

The technique can be used with a variety of polymers and coupling agents or combinations of coupling agents. Depositing the coupling agents from the vapor phase is faster than the conventional technique of depositing coupling agents from the solution phase, and this technique is useful with some polymers that react with or deteriorate in the solution that is used for depositing coupling agents from the solution phase.
