The brittleness of nanocellulose paper is a significant challenge that can limit its applications. To enhance its mechanical performance, various additives can be employed, including plasticizers, flexible polymers, and natural additives. Here’s a comparison of the effectiveness of these categories:
### 1. **Plasticizers**
Plasticizers are small molecules that can increase the flexibility and workability of materials.
- **Glycerol:**
