A Feasibility Study on Enclosing Nanocellulose in a Capsule

1. A Feasibility Study on Enclosing Nanocellulose in a Capsule Pei-Yu Kuo

2. Outline • Introduction • Material and Methods • Difficulties of Project

3. Introduction Nanocellulose or Microfibrillated Cellulose (MFC) • A high aspect ratio 5-20 nanometers width 100-2000 nanometers long

4. Introduction • High strength • High stiffness • Low weight • Biodegradability • Renewability

5. Introduction • Gel form is not suitable to storage or to transport. • With high water content • Fibers entangle easily • Compatibility to polymer is low and dispersion is bad

6. Introduction Polymer Nanocellulose

7. Introduction

8. Materials and Methods Homogenization

9. Materials and Methods Co-Electrospray Homogenization Depends on Nozzle Heat

10. Materials and Methods Pump 1 Voltage generator Pump 2 Nanocellulose PHB Jet Droplet Microparticles Alumnium foil

12. Difficulties of Project • Remove Solvent • Core/Shell ratio • Degree of Encapsulation • Payload • Particle Size
