Biodegradable composites based on well-characterized cellulose and poly (butyleneadipate-co-terephthalate)

As a biodegradable and flexible copolymer, poly(butyleneadipate-co-terephthalate) (PBAT) is used for packaging. However, high cost limited properties restrict its applications. Because of the hydrophobic nature PBAT, low mechanical are observed when PBAT cellulosic fibers, which hydrophilic, in blends. To increase interfacial adhesion between cellulose γ-(2,3-epoxypropoxy) propytrimethoxysilane (KH560) was as reactive compatibilizer to modify cellulose. A one-step method demonstrated compounding subsequent extrusion blowing, simple environmentally friendly approach fabricate series K-Cellulose/PBAT (KH560-Cellulose/PBAT) composites. The morphology structure were characterized by scanning electron microscopy, X-ray diffraction, Fourier transform infrared spectrophotometry. Meanwhile, thermal analysis hybrids showed an improvement stability composites with increased silanized content. In addition, barrier films measured water vapor permeability (WVP) oxygen (OP). Finally, after addition KH560, there considerable content, shown through testing. Therefore, prepared these enhanced have great potential substitutes traditional commodity polymers.
