초록
본 연구에서는 코로나 방전 처리에 의한 카본블랙/고무 복합재료와 코로나 처리 후 아크릴산 그래프트시킨 복합재료의 표면특성은 X-ray photoelectron spectroscopy (XPS)와 접촉각 측정을 통하여 알아보았으며, 복합재료의 접착특성은 박리접착강도(peel strength)를 측정하여 관찰하였다. 본 실험결과 코로나 처리에 의해 복합재료 표면에 산소를 함유한 극성관능기가 발달하여 표면자유에너지가 증가하였으며, 결과적으로 복합재료의 접착 특성인 박리접착강도가 증가한 것을 확인할 수 있었다. 또한 코로나 처리 후 아크릴산으로 그래프트시킨 복합재료의 경우 코로나 처리한 복합재료에 비하여 낮은 표면활성과 박리접착강도를 나타내었다. 이러한 결과는 카본블랙/고무 복합재료의 표면관능기 또는 표면자유에너지의 변화에 의한 것을 확인 할 수 있었다.
In this work, the effects of corona discharge treatment on surface properties of carbon black/rubber composites grafted with acrylic acid were investigated in terms of X-ray photoelectron spectroscopy (XPS) and contact angles. The adhesion characteristics of composites were studied by measuring the peel strengths of composites. As a result, the composite surfaces treated with corona discharge led to an increase in oxygen-containing functional groups, resulting in improving the degree of adhesion of the carbon black/rubber composites. Also, the acrylic acid grafting on the composites treated with corona discharge showed lower surface activity and peel strength, compared to those of the corona discharge-treated composites. These results are probably due to the modifications of surface functional groups or polar component of surface free energy of the carbon black/rubber composites.
