Following implantation, infections, inflammatory reactions, corrosion, mismatches in the elastic modulus, stress shielding and excessive wear are most frequent reasons for orthopedic implant failure. Natural polymer-based coatings showed especially good results achieving better cell attachment, growth tissue-implant integration, it was found that inclusions of nanosized fillers coating structure improves biomineralization consequently osseointegration, as nanoparticles represent calcium phosphate nucleation centers lead to deposition highly organized hydroxyapatite crystallites on surface. In this study, magnetic synthesized by co-precipitation method were used preparation cellulose acetate composite through phase-inversion method. The ability membranes tested Taguchi method, nanostructured formed at surface membrane (with a higher organization degree purity, Ca/P percentage closer one seen with stoichiometric hydroxyapatite, compared deposited neat acetate). obtained indicate potential new application field orthopedics.

Cellulose acetate (CA) was chemically modified with p-hydrazinobenzoic acid (HBA) for the fabrication of a CA-HBA polymeric membrane. The characterized using NMR, UV-Vis, and EDX/SEM techniques. exhibited high hydrophilicity, as it included carboxylic groups well hydroxyl group CA glycosidic ring. HBA moieties increased hydrophilicity number active sites inside matrix, but they did not improve thermal stability polymer, shown by thermogravimetry (TGA). Polysulfone (PSF) blended in various compositions to produce highly effective membranes water treatment applications. fabricated (CA-HBA/PSF) (5:95) (10:90) (15:85) were found exhibit stabilities.

Although crystalline nanocellulose (CNCs) can be extracted from different resources, the employed pretreatments, which disrupt inter- and intramolecular physical interactions, depend on biomass sources. This study aims to valorize Aloe Vera (AV) rinds into cellulose (CNC) employing two approaches during hydrolysis: sulfuric acid (CNCSA) citric (CNCCA) after 30, 60, 90 min of reaction. The effects pretreatments hydrolysis time functional groups hydrogen bonding in are discussed. Crystalline structure (polymorph type), crystallinity, thermal stability, morphology, particle size, metal presence also analyzed. A transformation type I II polymorph was achieved, where intermolecular interactions governing were increased CNCSA almost maintained CNCCA. Properties based structure, properties, indicate that CNCSA30 CNCCA90 samples displayed potential application as reinforcement agents for other types polymers having no more melting points 160 220 °C, respectively.
