“…A similar trend of properties was observed in PPC/PLA (70/30 wt%) blend with different concentrations (0–5 phr) of MWCNTs and PPC/PLA (40/60 wt%) blend with up to 5.34 vol% of carbon black (CB) incorporation . Unlike PPC/PLA (90/10 wt%) blend reported by Yang et al., the PPC/PLA (40/60 wt%) blend showed two clear T g values . These two T g values are, however, closer to each other, which suggests that PPC and PLA are partially miscible with 40/60 compositions.…”

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.

Impact strength, initial decomposition temperature and glass transition temperature of pure PPC and PPC/SF-PA66 composites Via hydrogen-bonding interaction, poly(propylene carbonate) (PPC) was firstly reinforced by polyamide 66 short fiber (SF-PA66). The tensile and impact strength, thermal stability of composites increased when the SF-PA66 content ranges from 5% to Downloaded by [UNSW Library] at 03:31 19 August 2015 2 20%, then decreased at 30%. The increment in impact strength, decomposition temperature of 5% mass loss and glass transition temperature of PPC/20%PA66 is 315.81%, 32.2 °C and 3.8°C, respectively. FTIR and 1 H NMR results illuminate that the introduction of hydrogen bonding interaction between PPC and SF-PA66. Moreover, the network structure formed when SF-PA66 content is higher than 20 wt%. It is confirmed by rheological responding curves that a plateau at low angle frequency occurs. In addition, a significant aggregation of SF-PA66 occurs when its content is 30 wt%, which causes the decrease in mechanical and thermal properties of PPC/SF-PA66 composites.

In this study, we simultaneously introduced both poly(lactic acid) (PLA) and multiwalled carbon nanotubes (CNTs) into the polyurethane (PU) matrix via melt blending, to achieve balanced mechanical properties and good conductivity. Different contents of PLA (0-30 wt%) and CNTs (0-3.0 wt%) were used in this work. A significant improvement in tensile strength at 300% strain and Young's modulus were observed, which could not be obtained by incorporating either PLA or CNTs with PU separately. Particularly, the ternary composites containing a large amount of PLA (30 wt%), 70PU/30PLA/CNTs composites, exhibit superior mechanical properties compared to other composites with less PLA content but the same amounts of CNTs. Moreover, the ternary composites showed better electrical conductivity compared with the binary counterpart. SEM observations demonstrated that PLA particles and CNTs are separately dispersed in the PU matrix. It was found that PLA particles remain spherical and their size increases with increasing PLA content up to 30 wt%, while a network structure of CNTs is formed with increasing its content, which was also confirmed via dynamic rheological analysis. Interestingly, some CNTs were seen to be located in the interfaces between PLA particles and the PU matrix for 70PU/30PLA/CNTs composites, namely, some CNTs exhibit a nano-bridge effect between PU and PLA. We hypothesized that the nano-bridge structure of CNTs in the composites could mainly contribute to the observed enhancement of mechanical properties and electrical conductivity.
