1. A method for fabricating a polymer composite material, comprising:
mixing a first polyol and an anhydride to form an oligomer (I) by an esterification reaction, wherein both ends of the oligomer (I) are carboxylic acid groups; mixing the oligomer (I) and a hydroxyethyl methacrylate (HEMA), wherein the hydroxyethyl methacrylate (HEMA) reacts with one end of the oligomer (I) to form an oligomer (II) in a condensation reaction; mixing the oligomer (II) with a triethanolamine or a triethylamine, wherein the triethanolamine or the triethylamine reacts with the oligomer (II) to form an oligomer precursor having an ionic group; mixing a second polyol with the oligomer precursor to form a mixture, wherein a hydroxyl group of the second polyol and the ionic group of the oligomer precursor generate a hydrogen bond; adding a double bond initiator into the mixture of the second polyol and the oligomer precursor, wherein the double bond initiator is capable to initiate a cross-linking polymerization reaction; and applying UV light or heat to the mixture of the second polyol and the oligomer precursor to generate the cross-linking polymerization reaction to cross-link the oligomer precursor and to form a phase changed cross-linking polymer, and the second polyol is encapsulated and dispersed in the phase changed cross-linking polymer.
