“…A slightly different approach to PLA properties’ modification is to use the fillers of specific characteristics. Recently, natural substances are gaining significant attention [ 17 , 18 , 19 , 20 , 21 , 22 ] as they may contribute extensively to the creation of sustainable polymeric materials. Therefore, in the previous years, considerable interest has been given to the nature-derived additives and the effect of processing conditions on mechanical, rheological, and thermal properties of the PLA/natural filler composites [ 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 ].…”

The study aimed to prepare sustainable and degradable elastic blends of epoxidized natural rubber (ENR) with poly(lactic acid) (PLA) that were reinforced with flax fiber (FF) and montmorillonite (MMT), simultaneously filling the gap in the literature regarding the PLA-containing polymer blends filled with natural additives. The performed study reveals that FF incorporation into ENR/PLA blend may cause a significant improvement in tensile strength from (10 ± 1) MPa for the reference material to (19 ± 2) MPa for the fibers-filled blend. Additionally, it was found that MMT employment in the role of the filler might contribute to ENR/PLA plasticization and considerably promote the blend elongation up to 600%. This proves the successful creation of the unique and eco-friendly PLA-containing polymer blend exhibiting high elasticity. Moreover, thanks to the performed accelerated thermo-oxidative and ultraviolet (UV) aging, it was established that MMT incorporation may delay the degradation of ENR/PLA blends under the abovementioned conditions. Additionally, mold tests revealed that plant-derived fiber addition might highly enhance the ENR/PLA blend’s biodeterioration potential enabling faster and more efficient growth of microorganisms. Therefore, materials presented in this research may become competitive and eco-friendly alternatives to commonly utilized petro-based polymeric products.

“…Demikian pula dengan sumber material yang digunakan juga berasal dari sumber yang sama. Meskipun serat tebu yang digunakan mengalami perlakuan alkali dengan larutan NaOH yang berbeda konsentrasinya, yaitu 8% berat selama 1 jam pada temperatur kamar, dimana kondisi ini berbeda dengan penelitian sebelumnya menggunakan konsentrasi larutan (20% v/v) serta temperatur 60-70℃ selama 4 jam, namun kondisi yang dipilih untuk penelitian ini diyakini menghasilkan kekuatan serat tebu yang lebih baik [8]. Jadi perlakuan alkali tidak menyebabkan penurunan kekuatan komposit.…”

“…Modifikasi yang dilakukan adalah pada konsentrasi larutan NaOH serta lama perendaman. Rujukan atas perubahan tersebut mengacu pada hasil studi sistematis yang dilakukan oleh Bartos et al (2020) dengan mempelajari pengaruh berbagai konsentrasi larutan NaOH mulai 1-15% berat selama 1 jam pada suhu kamar terhadap kekuatan serat tebu yang dihasilkan. Hasil studi menunjukkan kekuatan serat tebu maksimal dapat dicapai pada perendaman menggunakan larutan NaOH 8 % berat selama 1 jam pada suhu kamar [8].…”

Natural fibers used in the fabrication of biocomposite product can support the need of the industries for lightweight yet strong material. Sugarcane bagasse is one of the available natural fibers in Indonesia. There have been some research done on these bagasse fibers as reinforcement materials for plastics and their incorporation to the matrix has improved its strength. This research aimed to evaluate the fabrication of a car package tray prototype. The composition and the bagasse were prepared in accordance with the previous research in which the bagasse were alkali treated using NaOH solution of 8 wt% for one hour at room temperature. The hotpressed prototype was evaluated by its physical outlook and the mechanical property of its preform. The flexural test shows a low flexural strength of the prototype (7.4 MPa) compared to the required strength of the current material (woodboard) used by the industry (35.58 MPa). The evaluation shows the clustering of bagasse fibers, uneven distribution of sugarcane/PP in the structure and low adhesion at the interfacial region between bagasse fibers and PP.

“…Rising environmental awareness requires the development of materials which are less harmful to our habitat and take advantage of natural environment around us. In order to compromise the sustainable development rules and polymer technology, it is of a high importance to incorporate materials which are eco-friendly [9][10][11][12][13][14][15] and to limit the noxious chemical compounds employed in polymer processing [16][17][18][19]. Therefore, searching for some natural alternatives seems to be a great option and it is widely being developed [20][21][22][23][24].…”

The following article is the presentation attempt of cellulose hybrid chemical modification approach as a useful tool in improving the mechanical properties of plant fiber-filled polymer materials. The treatment process is a prolonged method of the cellulose maleinization and consists of two steps: 1. solvent exchange (altering fiber structure); 2. maleic anhydride (MA) chemical grafting (surface modification). Thanks to the incorporated treatment method, the created ethylene–norbornene copolymer composite specimen exhibited an improved performance, tensile strength at the level of (38.8 ± 0.8) MPa and (510 ± 20)% elongation at break, which is higher than for neat polymer matrix and could not be achieved in the case of regular MA treatment. Moreover, both the Payne effect and filler efficiency factor indicate a possibility of the fiber reinforcing nature that is not a common result. Additionally, the polymer matrix employed in this research is widely known for its excellent resistance to aqueous and polar organic media, good biocompatibility, and the ability to reproduce fine structures which makes it an interesting material regarding healthcare applications. Therefore, plant fiber-based polymer materials described in this research might be potentially applied in this area, e.g., medical devices, drug delivery, wearables, pharmaceutical blisters, and trays.
