“…The thermal resistance of most organic fillers does not exceed 200°C. Previously performed TG studies of corn stalks showed that the main stage of degradation of this material begins at this temperature 22 . Therefore, with a high content of organic filler in the composite, the observed decrease in resistance is significant.…”

“…Both visual and microscopic evaluations confirmed the positive deposition of the polydopamine coating on the ground corn stalk particles. Detailed effects of depositing a polydopamine coating on the surface of ground corn stalk (FTIR, EDS, TG, and DSC) were presented in the authors' previous work 22 . Following polydopamine deposition, the modified stem was incorporated into the polymer matrix, as explained in Section 3.2 and subjected to various tests.…”

“…The thermal resistance of most organic fillers does not exceed 200 C. Previously performed TG studies of corn stalks showed that the main stage of degradation of this material begins at this temperature. 22 Therefore, with a high content of organic filler in the composite, the observed decrease in resistance is significant. However, the obtained values of thermal resistance of the tested composites still significantly exceed the typical application temperatures of polymeric materials, so the registered decrease does not disqualify these materials from potential applications.…”

“…The authors conducted studies on the possibility of deposition of a polydopamine coating on particles of ground corn stalks, the results of which are presented in Ref. [22]. Studies have shown that as a result of the deposition process, polydopamine coatings formed on the surface of corn stalks, and the amount of deposited coating in most cases increased with increasing deposition time.…”

Modifying plant fibers before their incorporation into the polymer matrix is a crucial factor that influences the characteristics of the resulting composites. This article reports on a study that investigated how modifying ground corn stalks impacted certain properties of a biodegradable polymer composite. The composite was made up of a mixture of polylactide and polycaprolactone in a ratio of 70:30, and the filler was modified using dopamine hydrochloride to create a thin polymer layer of polydopamine on the surface of the particles. The study evaluated the structural, mechanical, thermal, and thermomechanical properties of composites that contained 30%, 40%, or 50% of the filler by weight. Additionally, the tests to determine how well the composites would compost in an industrial setting were conducted. The results of the study showed that modifying the filler particles had a positive impact on most of the properties tested, including tensile strength, flexural strength, Young's modulus, storage modulus, and impact strength. Interestingly, despite concerns about the antibacterial properties of polydopamine, the composting tests revealed that the modification of the filler particles did not have any negative effects on the industrial composting process.

“…Tannic acid (TA) is a natural plant-derived polyphenol. 6,31,32 It contains many catechol groups with high adhesive qualities, and can be oxidized to quinone in a pH range of 5-9. 9,24,[32][33][34] The side-chain amino group on the enzyme molecule can be combined with the quinone groups [35][36][37] of TA by the Schiff base reaction.…”

A carbon fiber‐tannic acid‐silicon dioxide (CF‐TA‐SiO2) reinforcement with a “diatom frustule‐like” structure was built via biomimetic mineralization to boost the performance of carbon fiber/epoxy resin (CF/EP) composites. As a bio‐based polyphenolic compound, TA was used to modulate the mineralization of SiO2, and the easy agglomeration of SiO2 was effectively avoided. The interfacial adhesion of the CF/EP composites was considerably heightened by improving the roughness and wettability of CF as well as by increasing the interfacial interactions between CF and the EP. Compared with the pristine composites, the flexural strength, interlaminar shear strength and interfacial shear strength of the CF‐TA‐SiO2/EP composites increased by 41.2%, 56.6%, and 50.4%, respectively. Moreover, the introduction of Si‐O‐Si and C‐O‐Si bonds at the interface led to a remarkable improvement in the hydrothermal aging resistance. This research provides a novel interfacial design for advanced composites with excellent interfacial properties, which broadens the application of these composites in hygrothermal environments.Highlights A “diatom frustules‐like” structure was successfully constructed on the CF surface. This biomimetic mineralization was simple and environmentally friendly. This method solved the problem of easy agglomeration of SiO2. The interfacial properties of composites were obviously improved. The hydrothermal aging resistance of composites was enhanced.
