Abstract
A composite includes a polymer network including pectin or a pectin derivative; a low-molecular compound having a hydrophilic group in the polymer network; and a polyvalent metal ion coordinated with an anion present in the polymer chain of the polymer network.
Claims22
An infrared absorber, comprising:
- a composite, wherein the composite comprises
- a polymer network including pectin or a pectin derivative;
- a low-molecular compound having a hydrophilic group and a molecular weight of less than or equal to about 500 g/mol in the polymer network;
- and
- a polyvalent metal ion coordinated with an anion present in a polymer chain of the polymer network,
- wherein the low-molecular compound is an ethylene glycol, propylene glycol, butylene glycol, diethylene glycol, dipropylene glycol, glycerol, or a combination thereof,
- wherein the low-molecular compound is included in the composite in an amount of greater than or equal to about 0.1 volume % and less than or equal to about 45 volume % based on a total volume of the composite.
