HDPE와 e-PTFE는 생체재료로서 골 조직공학 분야에서 널리 이용되고 있으나 두 재료 모두 소수성이 강한 특성을 가지고 있다. 이러한 단점을 극복하고자 저 압 및 대기압 플라즈마를 이용하여 각각의 재료표면을 친수성으로 개질을 하였 고, 표면의 물리화학적 특성변화를 확인 하였다. 또한 플라즈마 처리된 생체재 료의 in vitro 생체적합성을 조골모세포의 부착, 증식, 분화에 조사한 결과, 플 라즈마 처리가 매우 긍정적인 효과를 준 것으로 확인하였다. 이상과 같은 결과 로 미루어 보아 소수성이 강한 고분자 생체재료의 생체적합성을 개선하는데 저 압 및 대기압 플라즈마 기술은 매우 유용한 방법으로 적용될 것으로 사료된다.
