摘要：
The modulus of elasticity (MOE), hardness, and morphology of hydroxypropyl cellulose (HPC) fibril reinforced nanocomposites were analyzed using nanoindentation. It was observed that HPC composite with a fibril showed lighter and darker structures that can be explained by a contrast of crystalline fibril areas and the amorphous polymer matrix. The direct use of aqueous fibril suspensions for the compounding with HPC was found to be an effective method of dispersing the fibrils within the polymer matrix. The results show a homogeneous distribution of cellulose fibrils at higher magnifications.
