Properties of Cellulose Nanocrystal/Polyvinyl Alcohol-Based Nanocomposites |
| 초록 |
The characteristics of two types of cellulose nanocrystals (CNCs), i.e., cellulose nanowhiskers (CNWs) and cellulose nanofibrils (CNFs) and their reinforcement of polyvinyl alcohol (PVA)-based nanocomposites are described. CNWs were isolated by sulfuric acid hydrolysis while CNFs were isolated by 2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO)-mediated oxidation. Based on measurements by transmission electron microscopy of individual CNWs were about 6.96±0.87 nm wide and 178±55 nm long, while CNFs were 7.07±0.99 nm wide. The incorporation of CNWs and CNFs into PVA matrix at 5% and 1% levels, respectively, resulted in maximum tensile strength, indicating their different reinforcement efficiencies. These results suggest a relationship between the reinforcing potential of CNCs and their physical characteristics. |
