Abstract

A thermoplastic and thermoset foam nucleation additive, which is added to a foamed material, includes a gas absorbent and a nano-compound, wherein the nano-compound and the gas absorbent are mixed to form the thermoplastic and thermoset foam nucleation additive. The gas absorbent includes a central structure and a short chain structure, wherein a first chemical bond is formed between the short chain structure and the central structure. The nano-compound includes a base structure and a long chain structure, wherein a second chemical bond is formed between the long chain structure and the base structure. A number of carbon atoms in the short chain structure is not less than 8, and a molecular weight of the long chain structure is higher than 10000 g/mole.
