Poly(Vinyl Alcohol) Cellulose Nanocomposites

Abstract

Cellulose is the most abundant natural biopolymer in the world. Cellulose fibrils in micro- and nanoscales are attractive materials to replace man-made fibers such as glass and aramid fibers. They can be used as the reinforced additives or fillers to produce environmentally friendly materials. Poly(vinyl alcohol) (PVA) is a biodegradable polymer, which has many advantages including the resistance to solvents, being able to chemically bond with cellulose and soluble in hot water. The water solubility of PVA allows it to be fabricated with other water-soluble materials (e.g., nanocellulose solution) to form a nanocomposite by film casting method. In the introduction of this chapter, we overviewed the recently developed methods to generate cellulose fibril in a micro- or nanoscale, the characterization of nanocrystals and nanofibers, and the fabrication methods for PVA/cellulose nanocomposites. As an example, commercial microfibrillated cellulose (MFC) was used to reinforce PVA through film casting method in this chapter. The morphologies and sizes of the MFC were detected by scanning electronic microscopy (SEM). The effects of MFC on mechanical and thermal properties and surface morphologies of composites were studied. The introduction of MFC increased both tensile modulus and tensile strength of neat PVA. The composite had a higher thermal degradation temperature compared to neat PVA. The SEM images indicated the existence of interbonding between PVA and cellulose fibrils.
