Cellulose Microcrystal

The biodegradable composite films were prepared from bagasse microcrystalline cellulose as filler and poly(vinyl alcohol)(PVA) as polymeric matrix. The crystallinity, the tensile properties and the thermal properties of the composites were tested. Bagasse microcrystalline cellulose was distributed in PVA films as the crystalline state. The results show that the tensile properties and thermal properties were improved with the addition of bagasse microcrystalline cellulose. When bagasse microcrystalline cellulose mass fraction was 5%, both temperature of initial decomposition and maximum weight loss rate of composite film were raised by 11.71°C and 36.86°C, and the tensile strength increased by 17.88%, and the elongation at break increased by 36.62% compared to those of pure PVA.

All-cellulose composite using coconut shell powders (CSP) as natural lignocellulosic material and microcrystalline cellulose (MCC) were prepared by a surface selective dissolution. The effect of CSP content on tensile properties and crystallinity of CSP/MCC all-cellulose composites were investigated. It was found that the addition of CSP have increased the tensile strength and modulus of elasticity up to 3 wt% and decreased with further increment of CSP content. The elongation at break decreased with CSP content. The crystallinity of cellulose composites increased with the increasing of CSP content.

Cellulose Microcrystal

The biodegradable composite films were prepared from corn stalk microcrystalline cellulose as filler and poly(vinyl alcohol)(PVA) as polymeric matrix. The crystallinity, the tensile properties and the thermal properties of the composites were tested. Corn stalk microcrystalline cellulose was distributed in PVA films as the crystalline state. The results show that the tensile properties and thermal properties were improved with the addition of corn stalk microcrystalline cellulose. When corn stalk microcrystalline cellulose mass fraction was 10%, both temperature of initial decomposition and maximum weight loss rate of composite film were raised by 19.25°C and 17.17°C, and the tensile strength increased by 37.91%, and the elongation at break increased by 58.93% compared to those of pure PVA.
