Improvement of Barrier Properties by TEMPO-Oxidation Cellulose Nanofibers Spray Coating on Polypropylene Film |
| 초록 |
Polypropylene (PP) is one of the commonly used packaging materials because of its excellent thermal stability, water vapor barrier property, and transparency. However, due to the poor oxygen barrier property of PP, it is manufactured and used as a non-recyclable multilayer film with ethylene vinyl alcohol (EVOH) or polyamide (PA). In this study, TEMPO-oxidation cellulose nanofibers (TOCNFs) were used to improve the oxygen barrier property of PP. TOCNFs were easily dispersed in water, which allowed it to be simply coated on the PP using a spray coating method. The thickness of the coated TOCNFs layer was controlled at 200 to 500 nm by spraying time. O2 plasma treatment was used to improve the affinity of the interface between PP and TOCNFs. When the PP film was coated with TOCNFs, the oxygen transmission rate decreased from 1000 to 3 cc/m2·day·atm. In addition, it is easy to separate the coating layer and the PP substrate, so there is an advantage that can be recycle and reuse. |
