초록
가시광선에 의해 활성화되는 치아수복용 고분자 나노복합체를 제조하고 이들의 주요 물성을 고찰하였다. 복합체 제조에 사용한 충진재는 barium silicate와 나노 크기의 fumed silica가 혼합된 하이브리드 충진재를 사용하였으며 bisphenol A glycerolate methacrylate와 triethyleneglycol dimethacrylate로 구성되는 resin matrix와의 계면력 향상을 위해 실란 결합제로 표면을 소수성으로 처리하였다. 제조된 고분자 나노복합체의 기계적 물성을 평가한 결과, 나노 충진재가 첨가됨에 따라 내마모성이 향상되었다. 그러나 중합수축률 값은 나노 충진재 함량에 관계없이 3 vol% 이하로 거의 일정하였으며 광조사가 끝난 후에도 중합수축은 지속적으로 일어남을 알 수 있었다. 또한 복합체의 색차는 나노 충진재 함량이 늘어남에 따라 근소한 차이로 증가되었다.
Visible-light activated polymer nanocomposites (PNC) were designed to be used for dental restoration. Hybrid-filler composed of barium silicate and nano-sized silica was adopted as a filler system. To improve the interfacial be havior of the resin matrix of bisphenol A glycerolate methacrylate/triethyleneglycol dimethacrylate, the surface of filler was hydrophobically treated with a silane coupling agent. Mechanical properties of PNC were investigated by measuring the abrasion resistance, and it was discovered that PNC showed excellent properties with an increase of nanofiller content. However, the polymerization shrinkage was consistently maintained under 3 vol% and the shrinkage continued even after photo-polymerization. In addition, a slight color difference between PNC specimens was observed with increase of nanofiller content.
