Effect of Microfibrillated Cellulose on Microstructure and Properties of Poly(vinyl alcohol) Foams
Poly(vinyl alcohol) foams, containing different amounts of microfibrillated cellulose, were prepared through an eco-friendly procedure based on high-speed mixing and freeze-drying. The effect of filler amount on cell shape and regularity was studied by scanning electron microscopy (SEM) and the evol...
