Cellulose of bacterial origin, known as bacterial cellulose (BC), is one of the most versatile biomaterials that has a huge potential in tissue engineering due to its favourable mechanical properties, high hydrophilicity, crystallinity, and purity. Additional properties such as porous nano-fibrillar 3D structure and a high degree of polymerisation of BC mimic the properties of the native extracellular matrix (ECM), making it an excellent material for the fabrication of composite scaffolds suitable for cell growth and tissue development. Recently, the fabrication of BC-based scaffolds, including composites and blends with nanomaterials, and other biocompatible polymers has received particular attention owing to their desirable properties for tissue engineering. These have proven to be promising advanced materials in hard and soft tissue engineering. This review presents the latest state-of-the-art modified/functionalised BC-based composites and blends as advanced materials in tissue engineering. Their applicability as an ideal biomaterial in targeted tissue repair including bone, cartilage, vascular, skin, nerve, and cardiac tissue has been discussed. Additionally, this review briefly summarises the latest updates on the production strategies and characterisation of BC and its composites and blends. Finally, the challenges in the future development and the direction of future research are also discussed.

“…This phenomenon is the so-called relaxation behavior because the dipole moment cannot switch rapidly in sufficient time when the applied field is changed. 10 Furthermore, it is important to mention that all PLA−PCH and PLA-Ag/PCH hybrid films have a dissipation factor lower than 1.0 in a frequency range from 10 3 to 10 6 Hz, which is applicable to dielectric applications. Besides, the tendency of the hybridization is shown in Figure 7c by plotting the amount of Ag/PCH1 (phr) against the dielectric constant.…”

“…To enhance their dielectric properties, many hybrid polymers made from biodegradable polymers have been developed. 9,10 Perovskite ceramic materials such as barium titanate (BaTiO 3 ) and barium titanate doped with additional elements (Ba 1−x A x TiO 3 ) are the most common fillers used to improve dielectric characteristics. 11 Even though they have a high dielectric constant, the processing is not eco-friendly.…”

“…Based on the aforementioned, we intend to incorporate metal ions into PCH to improve its dielectric properties. Many metal fillers, such as Ni, Cu, Au, and Fe, were proposed for polymer matrices to enhance the dielectric constant of dielectric films. ,, Among the conductive fillers, silver (Ag) has an outstanding position because of its electrical conductivity, high thermal stability, antibacterial properties, and optical properties. Due to the highest electrical conductivity of silver, the dielectric constant can be, hence, enhanced by a small amount of Ag.…”

In this work, poly(lactic acid) (PLA) and nano-silver-coated porous clay heterostructure (PCH) hybrid films were successfully fabricated by a twin-screw extruder. Because of the low dielectric constant of PLA, nano-silver and PCH were employed to enhance the dielectric properties of PLA, and nano-silver-coated porous clay heterostructures (Ag/PCH) with different concentrations of Ag were synthesized by the green process using ascorbic acid as a reducing agent. The results revealed that 1 wt % of Ag-coated PCH (Ag/PCH1) exhibited the highest dielectric constant of up to 40. The physical, chemical, thermal, mechanical, and dielectric properties of pristine PLA and hybrid films were studied. The results indicated that adding Ag/PCH fillers could enhance the dielectric properties of hybrid films, increasing the dielectric constant almost 10 times higher than that of PLA. In addition, Ag/PCH could reinforce the mechanical properties of PLA. Furthermore, we prepared biaxially oriented poly(lactic acid) (BOPLA) films with 4 μm of thickness. The dissipation factor of BOPLA-Ag/PCH was improved, while the dielectric constant was only slightly decreased. However, the BOPLA-Ag/PCH showed better dielectric properties than those of traditional BOPP films. As a result, PLA-Ag/PCH and BOPLA-Ag/PCH hybrid films derived from poly(lactic acid) as biodegradable polymers with superior properties can be applied as dielectric films in capacitors.
