“…In turn, the temperature of a maximum mass loss for pure PLA and its composite with silanized fibers was reduced from 363.7 to 331.4 °C. A similar trend was established by Li et al who detected a reduction in the onset temperature from 344.2 °C for pure PLA to 246.4 °C for its composite prepared by solution casting with the use of silanized CMC as a filler and acetyl tributyl citrate as a plasticizer [ 171 ]. By preparing composites based on PHB with acetylated CMC, Ribero et al demonstrated that a slight improvement in thermal stability can be observed if the filler content does not exceed 0.5 wt%.…”

“…As seen, (3-aminopropyl)triethoxysilane (APTES), (3-methacryloyloxypropyl)trimethoxysilane (MPTMS), and (3-glycidoxypropyl)triethoxysilane (GPTES) are among the most-used silane agents. The effect of variation in silane agent amount on the properties of cellulose micro- and nanomaterials and their composites with aliphatic polyesters has been studied by several research groups [ 169 , 170 , 171 , 172 , 173 ].…”

“…In turn, Li at al. reported the modification of CMC with APTES in 90% ethanol in the presence of a catalytic amount of glacial acetic acid (pH 4–5) at room temperature [ 171 ]. The amount of APTES varied from 0.5 to 4.4 wt% relative to CMC.…”

“…The thermal stability of composites is one of the key properties when considering the thermoplastic-processing techniques. In general, the aliphatic polyesters filled with unmodified cellulose micro- and nanomaterials or modified with small molecules exhibit reduced thermal stability [ 142 , 171 , 255 ]. For example, Hong et al observed the decrease in thermal stability (TGA) of composite fabricated by injection molding in comparison with pure PLA [ 255 ].…”

“…The effect of the cellulose as filler to aliphatic polyesters on the degradation rates of biocomposites have been studied in several papers [ 171 , 234 , 237 , 251 , 259 , 260 ]. An investigation of enzymatically catalyzed (proteinase K) degradation of PLA composites with neat CNC and CNC modified by adsorption with acid phosphate ester of ethoxylated nonylphenol (surfactant Beycostat A B09) showed a lower weight loss for composites prepared with modified CNC via solution-casting technique [ 259 ].…”

Aliphatic polyesters/cellulose composites have attracted a lot attention due to the perspectives of their application in biomedicine and the production of disposable materials, food packaging, etc. Both aliphatic polyesters and cellulose are biocompatible and biodegradable polymers, which makes them highly promising for the production of “green” composite materials. However, the main challenge in obtaining composites with favorable properties is the poor compatibility of these polymers. Unlike cellulose, which is very hydrophilic, aliphatic polyesters exhibit strong hydrophobic properties. In recent times, the modification of cellulose micro- and nanomaterials is widely considered as a tool to enhance interfacial biocompatibility with aliphatic polyesters and, consequently, improve the properties of composites. This review summarizes the main types and properties of cellulose micro- and nanomaterials as well as aliphatic polyesters used to produce composites with cellulose. In addition, the methods for noncovalent and covalent modification of cellulose materials with small molecules, polymers and nanoparticles have been comprehensively overviewed and discussed. Composite fabrication techniques, as well as the effect of cellulose modification on the mechanical and thermal properties, rate of degradation, and biological compatibility have been also analyzed.

In the 1960s, the Swedish company Celloplast patented the first one‐piece plastic bag for packaging, and such plastic bags are heavily used all around the world until they are banned by some countries for environmental and sustainability reasons. Similarly, the EU banned certain single‐use plastic items in 2021—but food packaging is not part of this new regulation. And indeed, the majority of food packaging encountered today in the supermarket is still made from traditional, petrol‐based plastics. This review summarizes recent efforts in developing more sustainable alternatives to such petrol‐based food packaging. Different natural sources and production processes used to develop biodegradable, biopolymer‐based materials (bbMs) are discussed, which are categorized into natural bbMs, modified/plasticized bbMs, and plastic bbMs. An overview of the material properties of commercially available bbMs and bbMs developed in academic research projects is provided, and are compared with the properties of conventional, petrol‐based materials used for packaging. Furthermore, the role of academic and industrial contributors along the value chain of bbMs is highlighted and challenges that are responsible for the still limited occurrence of bbMs in daily lives are discussed.
