초록

표면이 개질된 셀룰로오스 마이크로/나노 섬유를 폴리(비닐 알코올)(PVA)과 혼합하여 복합필름을 제조하고 이들의 혼합 특성 및 치수 안정성 변화를 살펴보았다. 나노 섬유는 마이크로 섬유에 비하여 PVA와 혼합 특성이 우수하며 두 섬유 모두 표면 개질에 의하여 혼합 특성이 향상됨을 알 수 있었다. 이러한 혼합 특성 개선은 섬유 첨가에 따른 필름 헤이즈 현상을 감소시켜 PVA 필름의 광투과 특성이 우수해 짐을 확인하였다. 아울러 셀룰로오스 섬유 첨가는 PVA 필름의 치수안정성을 향상시키며 표면 개질 방법 및 정도에 따라 섬유 첨가가 필름 결정화도에 영향을 미쳐 이에 따른 치수안정성 변화를 확인할 수 있었다.

Poly(vinyl alcohol)(PVA) films with cellulose micro and nano fibers were obtained and their mixing characteristics and dimensional stability were studied. Cellulose nano fiber shows better mixing characteristic with PVA than cellulose micro fiber, resulting in that, PVA film with cellulose nano fiber shows lower haze and higher transmittance. Mixing characteristics and transmittance of both films enhanced by the surface modification of cellulose fibers. In addition, the dimensional stability of PVA films improved by both nano and micro cellulose fibers. The methods and the level of surface modification affect the degree of crystallinity in PVA film and dimensional stability.

Keywords:poly(vinyl alcohol);cellulose micro and nano fibers;transmittance;dimensional stability
