“…6. Both neat CNCs and PVDF showed one-stage degradation (the Cellulose decomposition started at around 195 and 370°C, respectively), which corresponded well with previous reports (Hietala et al 1998;Hu et al 2013). The thermal degradation of CNCs corresponded to the decomposition of long polymer glucose, while that of PVDF involved the formation of fragments corresponding to dimers, monomers and oligomers of vinylidene (Hietala et al 1998).…”

“…First, the size of PVDF spherulite and CNC were similar (Han et al 2013a, b), and therefore it is difficult to distinguish them. Second, CNCs were easily destroyed under the condition of electron beam exposure, especially when the morphology of CNCs was observed at a high magnification (Hu et al 2013). Further TEM work could help to clarify the dispersion state of CNCs within PVDF matrix in our ongoing work.…”

“…The prepared CNCs have many appealing advantages, such as high surface area, low weight, high tensile strength and Young's modulus (e.g., 7 and 130 GPa, respectively; Zhou et al 2011), which makes CNCs an ideal candidate as an environmentally friendly and effective reinforcing agent. Previously, CNCs as a reinforcing agent were added to a number of polymers, such as poly(vinyl alcohol) (Han et al 2013a, b), polyurethane (Pei et al 2011), poly(propylene carbonate) (Hu et al 2013), and poly(lactic acid) (Fortunati et al 2012).…”

Cellulose nanocrystals (CNCs) were used to improve the performance of poly(vinylidene fluoride) (PVDF), and the composite properties were characterized. The results showed that the prepared nanocomposites displayed the increases in mechanical properties. In particular, with the incorporation of 6 wt% CNCs, increases in tensile strength and dynamic storage modulus were observed. For hydrophilicity, the water contact angle decreased from 90°to 77°with the incorporation of only 3 wt% CNCs, indicating improved hydrophilicity. Addition of CNCs to PVDF also helped improve its thermal stability and crystallinity. It was suggested that CNCs played a nucleating role in the crystallization of PVDF, which was supported by the smaller size of PVDF spherulite observed from scanning electron microscopy analysis. Rheological results indicated that incorporation of CNCs also increased both melt storage modulus and shear viscosity of composites. Overall, our present work demonstrates that CNCs can provide PVDF with simultaneously improved properties.

“…As such, it appears that biodegradable and biocompatible CNCs have a higher reinforcing effect than the graphene oxide nanosheets, glass fibers, and montmorillonite in PPCs. Similar to PPC/nano CaCO 3 composites, and PPC/NCC, an enhancement in thermal stability was noticed in the PPC/CNC nanocomposites as compared to neat PPC . This was ascribed to the suppression of heat conduction by the CNC nanoparticles.…”

The conversion of CO2 into polymers such as poly(propylene carbonate) (PPC) can contribute to the reduction of dependence on fossil fuel resourced polymers. PPC is a polymer synthesized from the catalyzed copolymerization between CO2 and propylene oxide. The global demand for renewable and biodegradable polymers coupled with the recent success in catalysis for the copolymerization of CO2 with epoxides has paved the way for an increased interest and growth in PPC polymers. On the contrary, the extensive utilization of PPC in many applications is still challenging due to its poor thermal stability, mechanical strength, and dimensional stability. Thus, many research efforts currently focus on improving these limitations. On the other hand, polymer processing and application development efforts have continued to utilize the existing PPC. This article presents a comprehensive review of PPC polymer as a matrix component of polymer composites and nanocomposites. Progress in current research on PPC‐based material applications, including industrial packaging, electromagnetic shielding, energy storage, and biomedical applications are included. A critical review of the biodegradability, compostability, and overall sustainability of PPC is also conducted. Finally, challenges that limit the extensive use of such materials, and future research and development directions are highlighted.
