Biodegradable polymer composites from renewable resources are the next-generation of wood-like materials and crucial for development various industries to meet sustainability goals. Functional applications like packaging, medicine, automotive, construction sustainable housing just some that would greatly benefit. Some existing industries, wood plastic composites, already encompass given examples but dominated by fossil-based polymers unsustainable. Thus, there is a background bring new...
Typical resins for UV-assisted additive manufacturing (AM) are prepared from petroleum-based materials and therefore do not contribute to the growing AM industry trend of converting sustainable bio-based materials. To satisfy society industry’s demand sustainability, renewable feedstocks must be explored; unfortunately, there many options that applicable photopolymerization. Nevertheless, some vegetable oils can modified suitable technologies. In this work, extended study, through FTIR...
With the advancement of additive manufacturing (AM) and mass adoption 3D printing technology, it is essential to shift focus environmentally economically sustainable materials. As utilization renewable feedstocks quite limited in this context, more bio-based raw materials ongoing development AM represents an means achieving shift. In work, vat photopolymerization has been used process vegetable oil-based (VO) resins with ultralow concentration 0.07 vol % nanocellulose fibrils (NFC) crystals...
We report the manufacturing and characterization of poly (butylene succinate) (PBS) micro cellulose (MCC) woody-like composites. These composites can be applied as a sustainable composite alternative to conventional fossil polymer-based wood-plastic (WPC). The PBS/MCC were prepared by using melt blending 70 wt% MCC processed from bleached softwood. was modified enhance dispersion compatibility way carbodiimide (CDI), polyhydroxy amides (PHA), alkyl ester (EST), (3-Aminopropyl)...
Spent coffee waste from espresso machines was used as a renewable filler for the melt processing of sustainable poly(butylene succinate) biocomposites with enhanced exploitation properties.
Herein we introduce a plant oil-based elastomer system for 3D-printable soft robotics, offering high flexibility and resolution. Systems with varied mechanical properties in printed parts enable fast, delicate movements the shape memory effect.
There is an opportunity to use nanocellulose as efficient renewable reinforcing filler for polymer composites. have been many investigations prove the reinforcement concept of different sources thermoplastic and thermoset polymers. The present comparative study highlighted beneficial effects selecting cellulose nanofibers (CNFs) nanocrystals (CNCs) on exploitation properties vegetable oil-based composite materials—thermal, thermomechanical, structural characteristics. proposed...
The use of biobased materials in additive manufacturing is a promising long-term strategy for advancing the polymer industry toward circular economy and reducing environmental impact. In commercial 3D printing formulations, there still scarcity efficient resins. This research proposes vegetable oils as components to formulate stereolithography (SLA) resin. Application nanocellulose filler, prepared from agricultural waste, remarkably improves printed material's performance properties. strong...
Lignocellulosic fillers have been widely investigated for various polymer resin applications since they great potential using wood biomass and recycled plastics. However, besides cellulose nanocrystals (CNC) nanofibrils (CNF), not much of the other lignocellulose has used UV-curing resins. Even more so, none in hybrid combination compositions. In present work, effects such as lignin (LN)/CNC/CNF/hemicellulose (HC) with ratio-varying compositions on biobased resins wood-mimic material coating...
The current application of renewable resources in vat photopolymerization (VP) 3D printing is rather limited, emphasizing the importance incorporating bio-based materials into additive manufacturing (AM). In this study, VP technology was applied to create composites (derived from soybean oil-based resin) reinforced with cellulose nanocrystals (CNC). Two distinct modifications for CNC, i.e., acrylation and functionalization methyl methacrylate, were selected achieve strong bonding UV-curable...
The modern coating market is dominated by acrylic, polyurethane, and polyester polymer resins produced from unsustainable fossil resources. Herein, we propose the preparation of biobased components to produce functional solvent-free wood coatings with enhanced performance properties. Acrylated rapeseed, linseed, grapeseed oils were prepared via a one-step synthesis used as basis for control resin viscosity fatty acid content. A combination vegetable oil acrylates was matrix monomer...
The field of conductive polymer composites has been growing rapidly in recent years due to the increased demand for cutting-edge applications, such as sensors, soft robots, and other high-tech devices. Despite developing some biobased components, solutions that yield working prototypes are still lacking. Herein, a method making highly biobased, electroconductive, 3D printable (electrodes) is presented. A formulation composed acrylate-functionalized rapeseed oil (70 wt %) with addition...
In response to rising concerns over the environmental and human health ramifications of polymers derived from petroleum, particularly in food packaging industry, research has pivoted towards more sustainable materials. Poly(butylene succinate) (PBS), selected as polymer matrix, stands out one most promising bio-based biodegradable suitable for film blowing lamination.
