“…All bio-composite coating systems showed higher absorbance than neat acrylic coating. This could be attributed to the fact that the presence of bio-based additives in acrylic enhanced the optical properties of polymer coating in which contributing to the UV shielding properties (Peng et al , 2019). By that, the UV absorption properties of these bio-based additives could minimise the degradation of the neat polymer coating (Nuraje et al , 2013).…”

Purpose The purpose of this paper is to develop the bio-composite organic coatings by adding the bio-based additives that are extracted from banana peels and henna leaves as the organic corrosion inhibitors. Design/methodology/approach Bioactive constituents with inhibition properties are extracted from banana peels and henna leaves by using ethanol to form the ethanolic extract. The inhibiting efficiency of these bioactive constituents on mild steel corrosion in 3.5% sodium hydroxide (NaCl) solution is investigated. The investigation is performed using electrochemical impedance studies for 30 days. The optical and adhesive properties of the bio-composite coating systems have also been studied. Findings The best protection is obtained as the loading ratio of the banana peels ethanolic extract (BPEE) and henna leaves ethanolic extract (HLEE) are 10 Wt.% and 30 Wt.%, respectively. Overall, the results obtained show that the BPEE and HLEE not only enhance the optical properties but also can serve as an effective inhibitor for corrosion without affecting the adhesiveness of the neat acrylic properties. Originality/value Banana peels and henna leaves consist of bioactive constituents that have anti-corrosion properties which could inhibit corrosion.

The search for materials with better performance, longer service life, lower environmental impact, and lower overall cost is at the forefront of polymer science and material engineering. This has led to the development of self‐healing polymers with a range of healing mechanisms including capsular‐based, vascular, and intrinsic self‐healing polymers. The development of self‐healable systems has been inspired by the healing of biological systems such as skin wound healing and broken bone reconstruction. The goal of using self‐healing polymers in various applications is to extend the service life of polymers without the need for replacement or human intervention especially in restricted access areas such as underwater/underground piping where inspection, intervention, and maintenance are very difficult. Through an industrial and scholarly lens, this paper provides: a) an overview of self‐healing polymers; b) classification of different self‐healing polymers and polymer‐based composites; c) mechanical, thermal, and electrical analysis characterization; d) applications in coating, composites, and electronics; e) modeling and simulation; and f) recent development in the past 20 years. This review highlights the importance of healable polymers for an economically and environmentally sustainable future, the most recent advances in the field, and current limitations in fabrication, manufacturing, and performance.

“…The addition of titanium dioxide was aimed to achieve a good light‐shielding against UV radiations, a property that is fundamental to protect milk and dairy products from oxidation processes catalyzed by light. [ 16 ] The addition of polyvinyl alcohol (PVA) was aimed to evaluate the effect of blending with PLA with this barrier agent [ 17 ] in the case of an extra barrier property against oxygen permeation was required. The blending of PLA was obtained by mixing flexible polymers such as a co‐polyester of adipic acid, namely PBAT by the use of reactive compounding extrusion.…”

Mono‐material in the manufacturing of oil‐based plastic bottles has been so far not considered because of the poor flexibility of polyethylene terephthalate (PET). The undercuts of PET caps (i.e., the threads of the screw caps) would be torn‐off during the ejection step of the injection/compression molding processes that are commonly used to fabricate them. In this respect, the present work deals with the design and development of innovative biodegradable polyester‐based blends with high flexibility, intended for the manufacturing of screw‐cap, being this element the most critical in the implementation of the complete bottle. The blend is based on polylactic acid and it is tailored for injection molding of tamper‐evident screw plastic caps by the addition of another biodegradable polyester, that is, polybutylene adipate‐co‐terephthalate. The effect of the addition of a barrier agent, polyvinyl alcohol, on the overall behavior of the blends was also studied in the perspective of the implementation of caps featuring barrier properties against water vapor and oxygen. The same material could be, however, easily tailored for the fabrication of the bottle body and printed label to get to the mono‐material bottle. Twin‐screw corotating extrusion of the compound, injection molding of the plastic material for the fabrication of the screw caps, and evaluation of the thermophysical and mechanical properties of the screw caps are hereinafter discussed. The biodegradable polyester‐based blends are found to be suitable for injection molding of the tamper‐evident screw caps, exhibiting adequate flexibility during ejection from the mold. The screw caps can also boast appreciable mechanical strength and impact resistance as well as good thermal stability.
