Definitions
- This invention relates to solid ionically conductive polymers, structures and fuel cells incorporating same, and associated methods of production and use.
- conductive polymers A wide range of ionically conductive polymers are known, with possibly the most famous example being Nafion (RTM).
- Nafion (RTM) is a conductive membrane that conducts via cation conduction. Whilst Nafion (RTM) has achieved significant commercial success, there are problems associated with the material. In particular, Nafion (RTM) can only achieve useful conductivities in a swollen, hydrated state in which the material achieves volumes approximately 10 times greater than the volume associated with its unhydrated state. Thus, Nafion (RTM) membranes require constant hydration in order to function as conductive membranes and cannot operate conductively at high temperatures, eg, at greater than 100°C.
- the present invention in at least some of its embodiments, provides improvements to the prior art conductive polymers discussed above. Furthermore, the present invention can provide advantageous ways of applying conductive polymers and provides a class of conductive polymers that conduct by anionic conduction.
- a solid ionically conductive polymer having repeat units of a quaternary amine and including a plasticiser in an amount sufficient to render the polymer noncrystalline thereby increasing conductivity.
- the plasticiser may be present as an additive to the polymer.
- a preferred plasticiser of this sort is propylene carbonate.
- the polymer may contain between 5 and 60% by weight plasticiser additive. In order to produce polymers with reasonable mechanical strength, it is preferred that the polymer contains between 5 and 30% by weight plasticiser additive. For higher conductivities, the polymer may contain between 25 and 60% by weight plasticiser additive. In general, . polymers of this type exhibit somewhat poorer mechanical properties, but this may be acceptable or even desirable in certain applications. In some instances the polymer may contain more than 60% by weight plastic additive. Alternatively the polymer may be self-plasticising. The polymer can be self- plasticising in numerous ways.
- This polymer may include an anion present as a counterion to the quaternary amine, and the anion may act as a plasticiser.
- the quaternary amine itself acts as a self-plasticiser.
- larger anions and/or cationic quaternary amines render the polymer less likely to adopt a crystalline configuration.
- the polymer may contain a plurality of different plasticisers.
- the polymer may conduct by anionic conduction. It has been found that it is possible to provide anionically conducting polymers which exhibit conductivity comparable to H + conducting membranes. Alternatively, the polymer may conduct by cationic conduction, which may be proton conduction.
- the polymer is formed from the polymerisation of a monomer which comprises a group of sub-formula (I)
- R 2 and R 3 are independently selected from (CR 7 R 8 ) n , or a group CR 9 R 10 , CR 7 R 8 CR 9 R 10 Or CR 9 R 10 CR 7 R 8 where n is 0, 1 or 2, R 7 and R 8 are independently selected from hydrogen, halo or hydrocarbyl, and either one of R 9 or R 10 is hydrogen and the other is an electron withdrawing group, or R 9 and R 10 together form an electron withdrawing group, and

- Y 3 are independently selected from hydrogen, fluorine or other substituents
- R 1 is selected from hydrogen, halo, nitro or hydrocarbyl, optionally substituted or interposed with functional groups;
- Z is an anion of charge m.

- R 4 and R 5 are independently selected from CH or CR 11 where R 11 is an electron withdrawing group; the dotted lines indicate the presence or absence of a bond, X 1 is a group CX 2 X 3 where the dotted line bond to which it is attached is absent and a group CX 2 where the dotted line bond to which it is attached is present, Y 1 is a group CY 2 Y 3 where the dotted line bond to which it is attached is absent and a group
- CY 2 where the dotted line bond to which it is attached is present, and X 2 , X 3 , Y 2 and Y 3 are independently selected from hydrogen and fluorine; and R 1 is hydrogen or hydrocarbyl, and Z is an anion of charge m.
- the expression "in the substantial absence of solvent” means that there is either no solvent present or there is insufficient solvent present to completely dissolve the reagents, although a small amount of a diluent may be present to allow the reagents to flow.
- Conditions under which polymerisation occurs include the influence of radiation or an electron beam, heat or the presence of a chemical initiator. Radiation or electron beam induced polymerisation is suitably effected in the substantial absence of a solvent.
- R 7 and R 8 are independently selected from fluoro, chloro, alkyl or H. In the case of alkyl, methyl is most preferred.
- At least one, and possibly all, of X 2 , X 3 , Y 2 and Y 3 is a substituent other than hydrogen or fluorine.
- at least one, and possibly all, of X 2 , X 3 , Y 2 and Y 3 is an optionally substituted hydrocarbyl group.
