ADHESIVE STRENGTH ENHANCEMENT OF SHAPE MEMORY POLYMER COMPOSITE AND METAL JOINT |
| 摘要 |
A composite article, including a metal alloy haying a first surface and a shape memory polymer (“SMP”) adjoining the first surface, with a coupling agent condensed on the first surface between the metal alloy and the SMP. The coupling agent includes at least one metal alloy bonding group which chemically bonds to the metal alloy member and at least one SMP bounding group which chemically bonds to the SMP member. A method for forming the article includes resurfacing a first surface of the metal alloy and applying a coupling agent to the first surface, and then positioning the SMP thereon. The article is then treated to condense the coupling agent on the first surface. A toughening agent is optionally added to the SMP prior to coupling the SW and the metal alloy. |

1. A composite article, comprising:
a metal alloy member having a first surface; and a shape memory polymer (“SMP”) member having a second surface secured to the first surface by a coupling agent, wherein the coupling agent comprises a plurality of molecules with each molecule having at least one metal alloy bonding group that is chemically bonded to the first surface of the metal alloy member and at least one SMP bonding group that is chemically bonded to the second surface of the SMP member. |
