Abstract
There is provided an assembly for handling, transporting storing hydrogen, wherein the assembly comprises a component comprising a polymeric material (A) having a repeat unit of formula (I): —O—Ph—O—Ph—CO—Ph—(I) wherein Ph represents a phenylene moiety, and wherein the polymeric material (A) has a melt viscosity of at least 0.38 kNsm−2. Also provided are a use of the polymeric material (A) in a component of an assembly for handling, transporting or storing hydrogen and a method of handling, transporting or storing hydrogen.
Claims21
An assembly for handling, transporting or storing hydrogen, wherein the assembly comprises a component comprising a polymeric material (A) having a repeat unit of formula I:
- wherein Ph represents a phenylene moiety, and
- wherein the polymeric material (A) has a melt viscosity of at least 0.38 kNsm−2.
-21. (canceled)
A method of handling, transporting or storing hydrogen, the method comprising:
- (i) providing a component in an assembly for handling, transporting or storing hydrogen, wherein the component comprises a polymeric material (A), wherein the polymeric material (A) has a repeat unit of formula I:
- wherein Ph represents a phenylene moiety, and
- wherein the polymeric material (A) has a melt viscosity of at least 0.38 kNsm−2, and
- (ii) contacting the assembly with hydrogen so as to handle, transport or store the hydrogen.
A method of making a component for use in an assembly for handling, transporting or storing hydrogen, wherein the component comprising a polymeric material (A), a polymeric material (C), and a metal, the method comprising:
- (i) bonding a polymeric material (A) to a polymeric material (C);
- and
- (ii) bonding the polymeric material (C) to a metal;
- wherein the polymeric material (A) has a repeat unit of formula I:
- wherein Ph represents a phenylene moiety, and
- wherein the polymeric material (A) has a melt viscosity of at least 0.38 kNsm−2, and the polymeric material (C) has a repeat unit of formula I:
- wherein Ph represents a phenylene moiety;
- and a repeat unit of formula III:
- wherein Ph represents a phenylene moiety.
