“…This broad peak points to an amorphous structure of PGAG, which includes the short-range regular structure of PGAG chains and disordered structure of the amorphous phase. 37 PVDF exhibited peaks at 2 θ =18.4° and 20.3°, which are ascribed to the (020) plane of the α-phase and (200) plane of the β-phase, respectively. 31 α and β phases of PVDF were detectable from the XRD patterns of the PGAG/PVDF blend and their corresponding nanocomposites; however, tracing the changes of the characteristic peak intensity of the β-phase was somewhat difficult due to the overlapping of the XRD patterns of neat PGAG and PVDF.…”

“…Furthermore, considering glycerol polyesters’ still rising medical potential, − PBG will probably be very attractive for medicinal uses. What is more, in our best knowledge, it is one of the first or even the first unsaturated glycerol polyester which could easily react on the α,β-unsaturated moiety.…”

A new polyester poly(glycerol butenedioate) (PGB) was obtained in the bulk polycondensation of glycerin and maleic anhydride. Glycerol polyesters are new biomaterials commonly used in tissue engineering. PGB, containing the α,β-unsaturated moiety, could be very interesting due to potential modifications such as additions or oxidation. Such modifications are not possible on the heretofore known glycerol polyesters due to their structure without α,β-unsaturated moieties. In this work, the developed process was optimized by applying the design of experiments. The optimization criterium was the minimization of the E/Z isomer ratio. Applying the two-stage process, the E / Z isomer ratio was reduced from 5.5 to 0.5 compared to the one-stage process. The degree of branching was also reduced from 17 to 9%, as well as the degree of esterification from 0.89 to 0.72. The obtained structure can be used in modifying or cross-linking via Michael additions.

“…The dielectric nanocomposites have a high dielectric constant and a high dielectric loss at the low-frequency region. This makes them suitable for flexible organic electronics that can store charge effectively [ 5 ]. Dielectric loss spectroscopy (ε″) identifies BPNCs relaxation mode and interaction with nanofillers and matrices [ 31 ].…”

“…The incorporation of nanofillers into polymeric matrices not only improves the performance of BPNCs but also has an important effect on the elevation of their biodegradability. Nonetheless, It is imperative to acknowledge that no individual biodegradable polymer possesses the capability to fulfill all necessary criteria for a specific application [ 3 – 5 ].…”

Biodegradable polymer nanocomposites (BPNCs) are advanced materials that have gained significant attention over the past 20 years due to their advantages over conventional polymers. BPNCs are eco-friendly, cost-effective, contamination-resistant, and tailorable for specific applications. Nevertheless, their usage is limited due to their unsatisfactory physical and mechanical properties. To improve these properties, nanofillers are incorporated into natural polymer matrices, to enhance mechanical durability, biodegradability, electrical conductivity, dielectric, and thermal properties. Despite the significant advances in the development of BPNCs over the last decades, our understanding of their dielectric, thermal, and electrical conductivity is still far from complete. This review paper aims to provide comprehensive insights into the fundamental principles behind these properties, the main synthesis, and characterization methods, and their functionality and performance. Moreover, the role of nanofillers in strength, permeability, thermal stability, biodegradability, heat transport, and electrical conductivity is discussed. Additionally, the paper explores the applications, challenges, and opportunities of BPNCs for electronic devices, thermal management, and food packaging. Finally, this paper highlights the benefits of BPNCs as biodegradable and biodecomposable functional materials to replace traditional plastics. Finally, the contemporary industrial advances based on an overview of the main stakeholders and recently commercialized products are addressed.
