peer reviewed / We herein propose capitalizing on strong hydrogen bonding from novel bio-CO2-derived dynamic thermosets to achieve high-performance natural fiber composites (NFC) with circular features. CO2- and biomass-derived polyhydroxyurethane (PHU) thermosets were selected, for the first time of our knowledge, as matrices for their ability to ...
Since precision engraving is essential for almost any product or application, it is important that the printing system produces smooth and clear prints. In this regard, the rollers are made of steel and polymeric materials. However, light cylinder production is economical, transportation costs are very low, and it provides ease of transportation an...

The reuse of agricultural waste and the development of bio-based materials are the main strategies for solving the global energy crisis and environmental problems. Agricultural waste reeds containing natural nano-silica (SiO2) were liquefied with PEG-400, Castor oil, and acid to produce reed-based polyols (R–P). The result shows that the liquefied ...

Polyurethane/hydroxyapatite (PU/HA) composites are well-known for various biomedical applications. This study reports a chemical approach to improve the interaction between HA and PU matrix. HA was surface-modified with 1,6-hexamethylene diisocyanate (HMDI). First, an isocyanate-modified HA (IHA) was synthesized by hydro-thermal method. Second, IHA...

Polyurethane (PU) belongs to a unique class of polymers. Different properties of PU such as mechanical strength and biocompatibility can be enhanced by co-polymerizing it with different bio and synthetic polymers. It finds huge applications as micro-reactors for the fabrication of metal nanoparticles (MNPs) owing to the synergistic properties of bo...

Improving the nighttime vision of drivers is essential, given the growing advancements in urban transportation. In this study, polyurethane-based self-luminous pavement coatings (PSCs) were prepared by doping luminous powders (LPs) into the polyurethane materials. The superior optical properties and chemical stabilities of these coatings were ensur...
The aim of this work is to develop new polymer-based materials suitable for the design and 3D-printing of various biomedical implants and prostheses, in particular for cardiovascular applications. For that purpose, greener and safer alternatives to existing polyurethanes, called non- isocyanate polyurethanes (NIPUs), were investigated, and in this ...
