The exploitation of natural fibers to reinforce polymers is a promising practice. Thus, biocomposites have gained increased attention in automotive, construction, and agricultural sectors, among others. present work reports the reinforcement recycled high-density polyethylene (r-HDPE) with hemp afford composite materials as sustainable analogues conventional wood/plastic (WPC) products. HDPE bottles (postconsumer waste) were used r-HDPE further reinforced by addition fibers. For synthetic...
Ιn this work, new block poly(lactic acid)-block-poly(hexylene succinate) (PLA-b-PHSu) copolymers, in different mass ratios of 95/05, 90/10 and 80/20 w/w, are synthesized their thermal mechanical behavior studied. Thermal degradation stability the samples were examined by Thermogravimetric Analysis (TGA), while kinetics was applied to better understand process. The Friedman isoconversional method "model fitting method" revealed accurate results for activation energy reaction mechanisms (nth...
A series of high-density polyethylene nanocomposites filled with different diameter sizes (5, 15, and 25 μm) graphene nanoplatelets at various amounts (0.5-5 wt.%) are prepared by the melt-mixing method. The effect size filler content on mechanical properties is reported, results discussed in terms morphology state dispersion within polymer matrix. measured stiffness strength were found to be mainly influenced aspect ratio filler-matrix adhesion. Fractography was utilized study embrittleness...
The continuous depletion of natural resources coupled with plastics pollution, has prompted the scientific community to explore alternative biobased and/or biodegradable polymers. Poly(ethylene succinate) (PESu) is a promising substitute due its high processability and controllable biodegradation rate. Meanwhile, hemp possesses interesting properties such as being lightweight, exhibiting excellent long-term mechanical stability, having low carbon emissions, making it an ideal option for wood...
Fully biobased composite materials were prepared from poly(ethylene succinate) (PESu) and hemp fibers isolated agricultural wastes. Different amounts of incorporated in PESu 10% to 75%. Additionally, the effect Joncryl ADR® 4400 (JC) as a compatibilizer was investigated. The chemical structure, thermal behavior, crystallization, mechanical properties, antioxidant activity, hydrophilicity soil degradation studied. Mechanical properties are initially increased up 20-50% HF but decrease with...
Abstract High‐density polyethylene (HDPE) is one of the most popular plastics used in industry. Although it replaces many natural resources, due to low cost and easy processing, its ever‐increasing wastes make harmful for environment. Thus, processes are order recycle it. In present study, properties recycled HDPE (r‐HDPE) compared virgin investigated. The structural studies performed by X‐ray diffraction (XRD). thermal r‐HDPE measured thermogravimetric analysis (TGA) differential scanning...
This research addresses the current need for sustainable solutions in construction and furniture industries, with a focus on environmentally friendly particleboard. Particleboards were made from mixture of virgin wood chips hemp shives, which then mechanically recycled used to make new lightweight particleboards. Phenol–formaldehyde resin 25% w/w phenol replacement by soybean flour (PFS) was as binder lignocellulosic materials. Laboratory analyses determined properties, FTIR confirmed...
In the present work, Risperidone microparticles from poly(lactic acid)/poly(hexylene succinate) (PLA-b-PHSu) block copolymers in different ratios, 95/05, 90/10 and 80/20 w/w, were examined as long-acting injectable formulations. Nuclear magnetic resonance (NMR) was used to verify successful synthesis of copolymers. Enzymatic hydrolysis showed an increase weight loss content PHSu increased, while cytotoxicity studies confirmed biocompatibility The polyesters further encapsulate by spray...
Multiscale-reinforced polymers offer enhanced functionality due to the three different scales that are incorporated; microfiber, nanofiber, and nanoparticle. This work aims investigate applicability of polymer-based nanofabrics, fabricated via electrospinning as reinforcement interlayers for multilayer-fiber-reinforced polymer composites. Three examined; polyamide 6, polyacrylonitrile, polyvinylidene fluoride, both plain doped with multiwalled carbon nanotubes (MWCNTs). The effect nanotube...
