Adamantyl block type anion exchange membrane and preparation method thereof

The invention discloses an adamantyl block type anion exchange membrane and a preparation method thereof. The adamantyl block type anion exchange membrane can be used for alkaline fuel cells. The material of the anion exchange membrane is an adamantyl block type polyarylether polymer, the structure of the adamantyl block type polyarylether polymer comprises a long-sequence hydrophilic segment and a long-sequence hydrophobic segment, and rigid and large-steric-hindrance adamantyl groups are introduced into the hydrophilic segment and the hydrophobic segment of the block polymer. The preparation method mainly comprises the following steps: (1) synthesizing an adamantane-containing phenol monomer; (2) synthesizing an adamantyl polyarylether polymer; (3) bromination modification of the polymer; and (4) preparing the adamantyl block type anion exchange membrane. The prepared anion exchange membrane has a developed ion transmission channel, has the characteristics of high water content and low swelling degree, does
