Claim 0:
1. A composite for sensing heat or infrared light, the composite comprising:
a block copolymer including
a first structural group represented by Chemical Formula 1,
a second structural group represented by Chemical Formula 2, and
a third structural group represented by Chemical Formula 3; and

a polyvalent metal ion coordinated with a side chain group of the block copolymer,, wherein, in Chemical Formulas 1 to 3,
R11, R12, and R13 are independently hydrogen or a C1 to C6 alkyl group,
L11 and L12 are independently
a single bond,
a substituted or unsubstituted C1 to C10 alkylene group,
a C2 to C20 alkylene group in which at least one methylene group is replaced by a linker selected from —O—, —S—, —C(═O)—, —S(═O)—, —S(═O)2—, —C(═O)—O—, —O—C(═O)—, —C(═O)NR— wherein R is hydrogen or a C1 to C6 alkyl group, or a combination thereof, and
a substituted or unsubstituted C6 to C10 arylene group,

L13 is selected from a single bond, a substituted or unsubstituted C1 to C20 alkylene group, a substituted or unsubstituted C3 to C20 cycloalkylene group, and a substituted or unsubstituted C6 to C20 arylene group,
X is a carboxyl group (—COOH), a sulfonic acid group ((—S(═O)2OH), or a phosphoric acid group (—O—P(═O)(OH)2),
Y is selected from
a hydroxy group (—OH),
an alkoxy group (—OR, wherein R is a linear or branched C1 to C10 alkyl group),
an ester group (C(═O)OR, wherein R is a linear or branched C1 to C10 alkyl group),
a sulfonate ester group (—S(═O)2OR, wherein R is a linear or branched C1 to C10 alkyl group),
a phosphoric acid ester group (—O—P(═O)(OR)2, wherein R is a linear or branched C1 to C10 alkyl group),
an amine group,
an isocyanate group (—N═C═O), and
a urethane group (—NHC(═O)OR, wherein R is a linear or branched C1 to C10 alkyl group), and

Z is selected from
a substituted or unsubstituted linear or branch C1 to C20 alkyl group,
a substituted or unsubstituted C6 to C30 aryl group,
a substituted or unsubstituted C3 to C30 heteroaryl group,
a substituted or unsubstituted C3 to C30 cycloalkyl group, and a substituted or unsubstituted C3 to C30 heterocycloalkyl group.
