표면개질과 보강제를 이용한 의료용 접착제의 기계적 특성 향상

Improvement of Mechanical Properties of Bone Cement by Surface Modification and Reinforcement

조동련, 이경철

초록

저온 플라스마 공정을 이용하여 X-ray 비투과성 분말의 표면을 개질시키고, 소량의 운모, Kevlar섬유, 유리 섬유,탄소 섬유, 잘게 간 탄소 섬유 등을 보강제로 사용하여 의료용 아크릴 접착제의 기계적 특성을 향상시키고자 하였다. X-ray 비투과성 분말은 접착제가 굳은 후 인장강도와 피로강도를 저하시키는 요인이 되었으나 HMDSO/AA 플라스마로 표면을 개질시켜 접착제 기질과의 적합성을 높인 후에는 보강제 역할을 하였다. 잘게 간 탄소 섬유는 표면개질을 시켜 접착제 기질과의 적합성을 좋게 할 경우에 접착제의 피로강도를 크게 향상시켰다.

Improvement of mechanical properties of acrylic bone cement was tried by surface modification of radiopaque powder using a low temperature plasma process and by reinforcement with small amount of mica flake, Kevlar fiber, glass fiber, carbon fiber, or milled carbon fiber. Radiopaque powder which caused the reduction of tensile strength and fatigue strength of cured bone cement became a reinforcing material after it was surface-modified with HMDSO/AA Plasma to be compatible with the matrix. Fatigue strength could be greatly improved by milled carbon fiber, but only after It was surface-modified to be compatible with the matrix.

Keywords:bone cement;plasma;surface modification;reinforcement
