“…The combination of epoxidized oils and renewable acids was never considered in biopolyester blends and composites, with the exception of Liu et al [ 48 ]. This paper reported the use of polyphenolic tannic acid crosslinked epoxidized soybean oil oligomers for strengthening and toughening bamboo fibers reinforced PLA biocomposites.…”

The present work focused on the research, design, and study of innovative chain extender systems of renewable origin for PLA–based biocomposites, reinforced with wheat bran as filler. The majority of employed chain extender compounds belongs to fossil world, affecting the biodegradability property which characterizes biopolymers. The aim of this work was thus to find promising biobased and sustainable alternatives to provide the same enhancements. According to this objective, epoxidized soybean oil (ESO) was chosen as principal component of the chain extender systems, together with a dicarboxylic acid, malic acid (MA), or succinic acid (SA). The reactivity of the modifier systems was previously studied through thermogravimetric analysis (TGA) and IR spectroscopy, to hypothesize the reaction mechanism in bran–filled blends. Hence, small–scale extrusion was carried out to investigate the effects of ESO/MA and ESO/SA on formulations of different composition (both pure PLA blends and composites). The variation of melt fluidity parameters was analyzed to define the optimized concentration of modifier systems. A comparison between the effects on blends of designed biobased systems and the action of fossil–based Joncryl was performed, to understand if the developed green solutions could represent competitive and efficient substitutes. The modified composites were characterized in terms of mechanical tests, degradation and thermal studies (TGA and DSC), and morphological analysis (SEM), to figure out their main features and to understand their potential in possible industrial applications.

“…This is mainly because with the increase of ESO-SA 12 content, parts of ESO-SA 12 oligomer started to disperse within PLA matrix, which can significantly increase the chain mobility of PLA due to the plasticizing effect of ESO-SA 12 oligomer. 20 With the ESO-SA 12 content increasing from 4 to 16%, the Χ c of PLA decreased from 39.68 to 21.46%, confirming the strong heterogeneous nucleation effect of BFs' surfaces. While, with the BFs' surfaces modified by ESO-SA 12 , the heterogeneous nucleation sites for PLA were reduced, thereby reducing the crystallinity of PLA.…”

“…These two reasons can lead to the reduction of the PLA matrix strength and the composites. 20 The EB and the IS of the unmodified PLA/BF composite were 1.65% and 5.8 KJ/m 2 , respectively. Considerable increases in the EB and TS of the composites were achieved with the increase of the ESO-SA content.…”

“…Therefore, functionalized oligomers, including lactide grafted bamboo fiber (BF-g-LA), maleic anhydride (MA)-grafted PLA, and bio-based reactive vegetable oils, such as epoxidized soybean oil (ESO), maleinized linseed oil, and their-based oligomer have been incorporated into PLA/BF composites by reactive compatibilization to increase interfacial compatibility between matrix and fillers. [19][20][21][22][23][24][25][26] Through one-step dynamic vulcanization to in situ formation, grafted an oligomer and simultaneously prepared PLA/BF/compatibilizer ternary composites displaying the advantages of simplicity and high efficiency. [27][28][29] However, some problems are also encountered.…”

The application of bamboo fibers (BFs) to reinforce the impact strength of polylactic acid (PLA) is attractive because of its low cost and high specific strength.However, the main disadvantages of PLA/BF composites are their low compatibility and poor interfacial adhesion caused by different surface energies. In this work, a bio-based compatibilizer is used to modify PLA/BF composites with a BF content up to 30 wt%. First, sebacic acid (SA) and epoxidized soybean oil (ESO) are reacted to obtain ESO-SA oligomers with different branching and crosslinking structures. Next, ESO-SA is incorporated into a PLA/BF composite through dynamic vulcanization, and fully bio-based PLA/BF/ESO-SA ternary composites are prepared. Compared to the PLA/BF composite without ESO-SA addition, the impact strength of PLA/BF/16ESO-SA 12 increases from 5.8 to 14.55 KJ/m 2 . The toughening mechanism results confirm that the chemical structure of ESO-SA is the key indicator of the toughening efficiency.

The article presents a literature review of the plant origin natural compounds with biocidal properties. These compounds could be used as modifiers of biodegradable materials. Modification of polymer material is one of the basic steps in its manufacturing process. Biodegradable materials play a key role in the current development of materials engineering. Natural modifiers are non-toxic, environmentally friendly, and renewable. The substances contained in natural modifiers exhibit biocidal properties against bacteria and/or fungi. The article discusses polyphenols, selected phenols, naphthoquinones, triterpenoids, and phytoncides that are natural antibiotics. Due to the increasing demand for biodegradable materials and the protection of the natural environment against the negative effects of toxic substances, it is crucial to replace synthetic modifiers with plant ones. This work mentions industries where materials containing natural modifying additives could find potential applications. Moreover, the probable examples of the final products are presented. Additionally, the article points out the current world’s pandemic state and the use of materials with biocidal properties considering the epidemiological conditions.
