Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method of preparing thermoplastic nano-composite materials in which silicate salt layers are debonded and uniformly dispersed in a polymer matrix to be able to impart stronger mechanical reinforcing properties. SOLUTION: A method of preparing thermoplastic nano-composite materials comprises (a) a step of bringing a swelling phyllosilicate into contact with a polymerizable aminoaryl lactam monomer to insert the lactam monomer in between any adjacent layers of the phyllosilicate and (b) a step of accelerating the polymerization reaction of the lactam monomer by mixing the lactam monomer-inserted phyllosilicate with a thermoplastic polymer and heating the resulting mixture to effect the debonding of the phyllosilicate, thereby forming a thermoplastic nano-composite material in which the debonded silicate layers have been dispersed in the polymer matrix.
