“…Injection moulding is a method of making biopolymer-based products using a process that involves feeding, melting, injecting, and cooling the material in a mould [84]. The injection moulding technique is widely used for the mass production of biopolymers because it offers cost-efficient manufacturing and the ability to make a vast range of shapes.…”

The application of biopolymer materials in cladding presents a promising avenue for enhancing building sustainability, while addressing the limitations of conventional synthetic polymers. Cladding serves a dual purpose of protection and aesthetics for buildings, but increasing global energy consumption and environmental concerns necessitate the adoption of sustainable practices. The construction sector’s substantial energy usage and greenhouse gas emissions highlight the urgent need for sustainable building materials. Conventional cladding materials often lack sustainability and environmental compatibility. Biopolymers, derived from living organisms or by-products, offer a potential solution with their biodegradability, renewability, and low embodied energy. These materials can revolutionise cladding practices by providing eco-friendly alternatives aligned with sustainable construction demands. Integrating biopolymers with synthetic polymers can enhance material biodegradability, contributing to overall degradation. Prominent biopolymers like PLA, PHAs, starch-based polymers, cellulose, PHB, and PBS exhibit biodegradability and sustainability, positioning them in the front rank for cladding applications. Despite significant research in biopolymer applications in different fields, there is limited research to identify the application and limitations of biopolymers as building cladding materials. This review paper aims to bridge the research gaps by comprehensively analysing diverse biopolymer cladding materials based on their properties and exploring their cross-domain utility, thereby highlighting their transformative role in sustainable construction practices. The expanding biopolymer market in building cladding materials underscores their potential to drive innovation, with projected growth emphasising their importance.

“…Composite materials made up of a thermoplastic polymer matrix and a minor proportion of natural fibers are known as natural fiber-reinforced composites (NFRCs) [31]. Although extensive research has been conducted on the mechanical properties of NFRCs produced through traditional methods, such as extrusion and injection molding [31,32], the study of the mechanical behavior of 3D-printed PLA-based NFRCs [33][34][35][36] and the parameters of 3D printing processes, such as infill pattern and geometry [37], is still ongoing.…”

This research examines the impact of self-polymerized polydopamine (PDA) coating on the mechanical properties and microstructural behavior of polylactic acid (PLA)/kenaf fiber (KF) composites in fused deposition modeling (FDM). A biodegradable FDM model of natural fiber-reinforced composite (NFRC) filaments, coated with dopamine and reinforced with 5 to 20 wt.% bast kenaf fibers, was developed for 3D printing applications. Tensile, compression, and flexural test specimens were 3D printed, and the influence of kenaf fiber content on their mechanical properties was assessed. A comprehensive characterization of the blended pellets and printed composite materials was performed, encompassing chemical, physical, and microscopic analyses. The results demonstrate that the self-polymerized polydopamine coating acted as a coupling agent, enhancing the interfacial adhesion between kenaf fibers and the PLA matrix and leading to improved mechanical properties. An increase in density and porosity was observed in the FDM specimens of the PLA–PDA–KF composites, proportional to their kenaf fiber content. The enhanced bonding between kenaf fiber particles and the PLA matrix contributed to an increase of up to 13.4% for tensile and 15.3% for flexural in the Young’s modulus of PLA–PDA–KF composites and an increase of up to 30% in compressive stress. The incorporation of polydopamine as a coupling agent in the FDM filament composite led to an improvement in tensile, compressive, and flexural stresses and strain at break, surpassing that of pure PLA, while the reinforcement provided by kenaf fibers was enhanced more by delayed crack growth, resulting in a higher strain at break. The self-polymerized polydopamine coatings exhibit remarkable mechanical properties, suggesting their potential as a sustainable material for diverse applications in FDM.

“…Part of the polyethylene family, HDPE occupies second place in the most commonly used plastics list due to its good chemical resistance ability, along with high flexibility, weatherproof properties, good low temperature toughness and low cost [ 5 ]. PP, a partially crystalline and non-polar polymer that belongs to the polyolefins group, is located at the fifth place as one of the most durable types of plastic [ 6 , 7 ].…”

Exploring the Surface Potential of Recycled Polyethylene Terephthalate Composite Supports on the Collagen Contamination Level

et al. 2023

View full text Add to dashboard Cite

With a significant number of features (namely being multipurpose, inexpensive and durable), thermoplastic polymers, most often named plastics, are part of our daily routine, with an increasing production over the last decade. Among them, polyethylene terephthalate (PET), high-density polyethylene (HDPE) and polypropylene (PP) are distinguished as the five most commonly used plastics in various fields, mainly in the packaging industry. Even if it is difficult to imagine the world without plastics, the boosted plastic assembly comes with huge plastic waste, creating a number of challenges, as the most important threat for our environment, but also opportunities for recycling. Currently, a special attention is dedicated on how to improve the current recycling methods or to find new ones, since the quality of recycled plastics and potential chemical or biological contaminations are two problematic aspects. Understanding the properties of each thermoplastic polymer and the interaction with possible contaminants may be the key for an efficient recycling process. The aim of this paper was to evaluate the surface behaviour of different composite supports based on recycled PET before and after interaction with collagen (used as a biological contaminant). The surface contamination bias of PET supports was studied through different techniques: scanning electron microscopy (SEM), water uptake through swelling studies, contact angle measurements and attenuated total reflection–Fourier transform infrared spectroscopy (ATR-FTIR).
