졸-겔 공정을 통한 실리카 캡슐화 에이코산 상변화물질 합성

초록

This study reports the successful fabrication of n-eicosane@silica phase change materials (PCMs) using a sol–gel synthesis method. Fourier-transform infrared (FTIR) analysis confirms the presence of both n-eicosane and silica, indicating effective encapsulation. Scanning electron microscopy (SEM) reveals well-defined core–shell structures with uniform morphology. The encapsulated PCM exhibits enhanced thermal stability and reliable phase change behavior, addressing leakage issues commonly associated with organic PCMs. These results demonstrate that the synthesized n-eicosane@silica composite is a promising candidate for efficient thermal energy storage applications, particularly in areas requiring long-term thermal reliability. The sol–gel approach provides a simple and scalable route for developing advanced PCMs with improved structural integrity and performance for sustainable energy management systems.
