Facile Preparation Route of Cellulose-Based Flame Retardant by Ball-Milling Mechanochemistry.

In this study, a sustainable cellulose-based flame-retardant additive was developed, characterized, and incorporated into polypropylene (PP). Microcrystalline cellulose (Cel) was chemically modified with PO using the solvent-free ball-milling mechanochemistry approach at room temperature. This modification enabled phosphorus grafting onto cellulose, significantly enhancing the cellulose charring ability and improving the thermal stability of the char as revealed by thermogravimetric analysis (TGA).

Characterization and Antimicrobial Activity of Extracts Encapsulated in Hydroxyapatite Sodium Silicate Glass Composite.

is an interesting source of bioactive compounds commonly used for various therapeutic purposes. Associate its seeds extracts with biomaterials to improve their antimicrobial properties are highly demanded. This study aims to investigate the encapsulation of extracts in hydroxyapatite nanoparticle sodium silicate glass (nHap/SSG) scaffold.

Synthesis and characterization of composite based on cellulose acetate and hydroxyapatite application to the absorption of harmful substances.

The aim of this work is to develop composite materials with hydroxyapatite (HAp) mineral and organic matrix such as cellulosic polymers. We use cellulose acetate with different percentages, and then inorganic-organic films were fabricated by evaporation of solvent. The composite films were characterized using emission scanning electron microscopy (FEG-SEM), thermo-gravimetric analysis (TGA) and Fourier transform infra-red (FT-IR) spectra.
