Green and scalable fabrication of core-shell bio-based flame retardants for reducing flammability of polylactic acid
The design of flame-retardant biocomposites based on biobased flame retardants (FRs) represents a promising direction for creating a sustainable world. To date, it remains a major challenge to explore a green and calable strategy for the design of highly effective, biobased FRs for bioplastics, such as polylactic acid (PLA). Herein, we have demonstrated a green, facile fabrication approach for a...

(Eur. Polym. J.) Synthesis of Fully Bio-based Diepoxy Monomer with Dicyclo Diacetal for High-performance, Readily Degradable Thermosets
Thermosets are very versatile owing to their high dimensional stability, chemical resistance and thermal and mechanical properties; however, they are difficult to be recycled or reworked because of their permanent cross-linked structure. In this paper, we synthesized a novel fully bio-based diepoxy monomer via acetalization of lignin derivative vanillin with bio-based polyol erythritol followed ...

Bio-oil production from hydrogenation liquefaction of rice straw over metal (Ni, Co, Cu)-modified CeO2 catalysts
This paper describes catalytic hydrogenation liquefaction of rice straw over metal (Ni, Co, and Cu)-modified CeO2 catalysts for bio-oil production. The results show that the highest rice straw conversion (89.08%) and bio-oil yield (66.7%) were obtained over Ni/CeO2 catalyst. The bio-oil contains mainly phenols, high-value-added, and widely used chemicals. Furthermore, metal-modified CeO2 catalys...

Catalytic hydroliquefaction of rice straw for bio-oil production using Ni/CeO2 catalysts
A series of Ni/CeO2 catalysts were synthesized via a simple one-pot hydrothermal method and characterized by XRD, SEM, TEM, EDX, EDX mapping, Raman, H-2-TPR, BET, XPS, TGA and ICP-MS. Their catalytic performances were systematically evaluated in hydroliquefaction of rice
straw. The impact of reaction temperature, reaction time, H-2 pressure and Ni/Ce molar ratios on product yields and distrib...

【Nano Research】Bio-Inspired Design Of Hierarchical FeP Nanostructure Arrays For The Hydrogen Evolution Reaction
Hierarchical FeP nanoarray films composed of FeP nanopetals were successfully synthesized via a bio-inspired hydrothermal route followed by phosphorization. Glycerol, as a crystal growth modifier, plays a significant role in controlling the morphology and structure of the FeO(OH) precursor during the biomineralization process, while the following transfer and pseudomorphic transformation of the ...

The preparation of fully bio‐based flame retardant poly(lactic acid) composites containing casein
In this work, a bio-based flame retardant, casein, was incorporated into poly(lactic acid) (PLA) matrix by melt compounding in order to improve the fire resistance and sustain the biodegradable character of PLA simultaneously. The fire performance of PLA composites was evaluated by limiting oxygen index, UL-94 vertical burning, and cone calorimeter tests, respectively. The results indicated that...

Combination of a bio-based polyphosphonate and modified graphene oxide toward superior flame retardant polylactic acid
The superior flame retardant polylactic acid (PLA) composites were prepared using the bio-based polyphosphonate (BPPT) and polyethyleneimine modified graphene oxide (MGO) as flame retardant at very low loading amounts. Within 2.4 wt% BPPT and 0.6 wt% MGO in the polymer matrix, the as-prepared PLA composites can pass UL94 V0 grade and achieve a LOI value of 36.0. The cone tests and TG-FTIR results ...
