“…Furthermore, the thermal property of ZnO-PPCs was improved in response with the increase of the ZnO content. Inversely, the opposite phenomenon was recorded in the case of decreasing the polymerization temperature with the same feeding reactants amount (entry 5&6, 7&8), which could be deduced by the effect of the PPC molecular weight [1,4]. All the nanocomposite samples showed remarkably higher T d than PPC itself, indicating that the thermal stability of PPC was substantially improved by incorporation of ZnO NPs.…”

“…All the nanocomposite samples showed remarkably higher T d than PPC itself, indicating that the thermal stability of PPC was substantially improved by incorporation of ZnO NPs. This thermal stability improvement was considered to covalent bonding between PPC and ZnO, which weakened the random main chain thermal scission, as well as chain unzipping reaction, of PPC [1,3].…”

“…Poly(propylene carbonate) (PPC), a biodegradable and biocompatible aliphatic polycarbonate composed of carbon dioxide (CO 2 ) has attracted extensive attentions with a potentially wide range of applications [1,2]. The incorporation of CO 2 into a polymer is an efficient route to reduce CO 2 greenhouse gas pollution, "white pollution", and overcome shortages in petroleum [3][4][5].…”

A series of nanocomposites composed of poly(propylene carbonate)(PPC) andZnO nanoparticles (NPs) were synthesized and characterized. Initially, (3-glycidyloxypropyl)trimethoxysilane was used to introduce epoxide groups onto the ZnO surface. Subsequently, the modified ZnO NPs were incorporated in PPC matrices by ring-opening copolymerization of epoxide groups on the surface of ZnO NPs and propylene oxide with carbon dioxide. The structures of the modified ZnO NPs and nanocomposites were confirmed by fourier transformed infrared spectrometry analysis. The morphology of the nanocomposites was investigated by scanning electron microscopy and transmission electron microscopy, where ZnO NPs were well dispersed in the polymer matrix. The thermogravimetric analysis study showed that the nanocomposites exhibited remarkable increasing in thermal property compared to the neat polymer.

“…Thus, it may improve the affinity between binder and organic liquid electrolytes. Furthermore, PPC is an amorphous polymer and it has good thermal stability above 200 °C, while PEO starts to degrade around only 50 °C in air. Therefore, this study aims to understand how these PVDF‐based blends contribute to the microstructures, interfaces and so the electrochemical performance of the electrode composites.…”

Polymer binder plays a critical role in controlling the microstructure of electrode composites. Compared to synthesizing new binder molecules, polymer blends combining the advantages of different polymers represent a low‐cost, facile, and effective strategy for the design of advanced binder systems. In this study, we aim to improve the poly(vinylidene fluoride) (PVDF) binder performance by blending with other functional polymers, including polyethylene‐block‐poly(ethylene glycol) (PE‐PEG) co‐polymer and poly(propylene carbonates) (PPCs). It is found that the PE‐PEG co‐polymer acting as a surfactant for carbon black (CB) can improve the dispersion of CB and, thus, result in a more uniform conductive network in the electrode composites. The addition of PPC, an amorphous polymer with good affinity to liquid electrolytes, can reduce the crystallinity of PVDF and improve the component interactions. Benefiting from the improved structure uniformity, the specific capacity and C‐rate performance of the resultant electrodes were notably improved, as compared with that of pure PVDF binder. These results indicate that polymer blending is a facile method to modify the PVDF binder and improve the uniformity and interfaces of electrode composites.

“…PPC can be used in the manufacture of packing materials, coatings and adhesives. In addition, it is used in a variety of applications in the biological medicine industry, which has now become a research hotspot . However, PPC also has several disadvantages, including a low glass transition temperature and poor thermal stability, which restrict its large‐scale industrial application …”

In the present work, with the application of diphenylmethane diisocyanate (MDI) as the chain extender, poly(propylene carbonate) (PPC) was modified by chain extension. The changes in the chemical, thermal and mechanical properties of PPC after modification were characterized by Fourier transform infrared spectroscopy, gel permeation chromatography, thermogravimetry and elemental analysis. The experimental results indicate that during melt blending of MDI and PPC the terminal hydroxyl group in PPC can react with the isocyanate group in MDI, leading to chain extension of PPC. Via modification, the physical properties and thermal stability of PPC can be enhanced considerably. With the addition of 1.5% MDI, the glass transition temperature increased from 14.1 °C to 28.2 °C and the thermal decomposition temperature T−5% increased from 162.7 °C to 246.8 °C. Moreover, the tensile strength of the modified PPC was improved from 3.1 MPa to 20.3 MPa. © 2015 Society of Chemical Industry
