Article and method of making the same

Abstract

An article comprises a substrate having a first portion comprising at least one of a metal or a ceramic metal oxide. A composite foam is bonded to the metal or ceramic metal oxide. The composite foam comprises: at least one polymer preparable by ring-opening metathesis polymerization; at least one catalyst for the ring-opening metathesis polymerization; at least one difunctional coupling agent represented by Z—X—Z. Each Z independently represents a group that is chemically reactive with at least one of the chemically bound surface hydroxyl groups thereby forming at least one covalent bond. Each X independently represents a divalent organic linking group having a number average molecular weight of 500 to 10000 grams per mole; and at least one of hollow glass microspheres or expanded polymeric microspheres. A method of making the article is also disclosed.
