Abstract

Three types of parylene (PA-N, PA-C, PA-D) were used for coating the surface on natural latex rubbers in order to improve surface characteristics including mechanical properties and biocompatibility. The parylene coating was the CVD (chemical vapor deposition) method, and the surface properties of the modified latex were measured. Annealing effects on the mechanical properties of the coated latex were also investigated. The adhesion between latex and parylene was good for all the types of parylene used. As annealing temperature was increased, latex modified with PA-N became more hydrophobic, while the latex treated with PA-C and PA-D became more hydrophilic. As the annealing temperature was raised, the tensile strength was increased, and the elongation was decreased. The biocompatibility was noticeably improved on the latex surface modified with the parylenes through CVD method.

라텍스 고무의 기계적 성질과 생체적합성 등의 표면특성을 개선하기 위하여 3가지 종류의 패럴린(PA-N, PA-C 및 PA-D)을 라텍스 고무 표면에 증착하였다. 패럴린 증착은 화학기상증착법(chemical vaper deposition)법을 이용하였으며, 증착필름의 표면특성을 조사하였다. 증착 후 열처리에 의한 증착 필름의 기계적 성질 변화를 조사하였다. 패럴린 증착 필름과 라텍스 고무와의 접착력은 PA-C와 PA-D 모두 우수하였다. 열처리 온도가 증가함에 따라 PA-N의 경우는 접촉각이 커져 보다 소수성 쪽으로 변화는 경향을 보였으며, PA-C와 PA-D는 친수성에 가까운 쪽으로 변화하였다. 열처리 온도가 증가할수록 인장강도는 증가하고 연신율은 감소하였다. CVD법으로 증착된 패럴린 박막은 우수한 생체적합성을 나타내었다.
