“…Approximately 5.0 g PLA were dissolved into 60 mL chloroform by stirring in a 50°C water bath. The solution was blended with 2.5 w/w% silylated BCNW and ultrasonic stirring to disperse them for 30 min . The blended suspension was cast in a self‐made PTFE mold (diameter: 80 mm) and air‐dried for 48 h, and then dried it in a vacuum oven at 60°C for 4 h. Then, PLA/BCNW biocomposite films were fabricated with a thickness of 0.3–0.5 mm.…”

“…In this regard, the crystallization and the thermal and mechanical properties of the composites would be improved. The optimal BCNW addition content was found at 2.5 wt% and reached the maximum elongation at break value of 22.27% . However, the interfacial compatibility was found to be insufficient; a surface modification between BCNW and PLA was still needed.…”

“…In our previous study, bamboo cellulose nanowhisker (BCNW) from moso bamboo residues were extracted; its physical and chemical properties were characterized in detail . BCNW, a rod‐like shape that has a large length‐to‐diameter ratio, may act as a nucleating agent or plasticizer in PLA composites . In this regard, the crystallization and the thermal and mechanical properties of the composites would be improved.…”

To improve the surface compatibility between hydrophobic poly(lactic acid) (PLA) and hydrophilic bamboo cellulose nanowhiskers (BCNWs), four commercial available silane coupling agents were employed to modify their interfaces with different concentrations (0, 1, 8, and 16 wt%). PLA/BCNW biocomposite films were fabricated by solution casting. The effects of silylated BCNW on the thermal, mechanical, and morphological properties of PLA biocomposites were investigated. The coupled reaction between coupling agents and cellulose via Si‐O‐C bonding and hydrogen bonding was confirmed. Both, tensile strength and tensile modulus, decreased with the four silane treatments. The maximum elongation at break values increased to 213.8, 111.3, 255.3, and 209.8% after 16 wt% A‐151, 8 wt% A‐1100, 8 wt% A‐174, and 8 wt% A‐189 silane treatments, respectively, with respect to 12.4% of the untreated composite. A wire‐drawing phenomenon was observed on the tensile fractural surface. Glass transition temperature and crystallinity decreased after the surface modifications. POLYM.

“…The crystallinity was determinate by eqs. and considering the theoretical value of fusion enthalpy for PBAT and PLA, 114 and 93,6 J/g, respectively . The samples followed the same trend presenting low values of crystallinity with the addition of CaCO 3 compared to the neat matrix.…”

The use of flexible films in agriculture has increased intensely in the last 15 years bringing benefits to producers. However, environmental impacts increased due to their incorrect post‐use disposal which leads the degradable films to emerge as an alternative. The production films of poly(butylene adipate‐co‐terephthalate) and poly(lactic acid) reinforced with calcium carbonate (CaCO3) was studied focusing on producing lower cost materials and flexible films. Four different films (reinforcement compositions) were prepared by melt extrusion with 10 and 20 wt % of CaCO3. Mechanical and thermal properties, crystallinity, water absorption, and soil degradation, were evaluated. The addition of reinforcement leads to improved compatibility between the polymers in the matrix, which usually presented phase segregation. The films showed better mechanical properties with the addition of CaCO3. Highly orientated amorphous structures were obtained leading to low water absorption and low degradation in the simulated soil. This low degradation, suggests that the obtained films would be of interest in flexible mulch films manufacturing, particularly for Muridori plantation system, where long‐term plantations are needed. © 2018 Wiley Periodicals, Inc.
