Fabrication of poly(vinyl alcohol) nanocomposites having different contents of modified SiO2 by vitamin B1 as biosafe and novel coupling agent to improve mechanical and thermal properties

Abstract

In this study, at first, owing to the excessive surface energy and inclination for aggregation, surface treatment of silica (SiO2) nanoparticles (NP)s was performed by vitamin B1 (VB1) as a biodegradable and biocompatible coupling agent.

Poly(vinyl alcohol)/Vitamin C-multi walled carbon nanotubes composites and their applications for removal of methylene blue: Advanced comparison between linear and nonlinear forms of adsorption isotherms and kinetics models

Abstract

The fabrication of glutaraldehyde (Gl)-crosslinked poly(vinyl alcohol) (PVA)/Vitamin C (VC)-multi walled carbon nanotubes (VC-MWCNTs) composites and their adsorption capacity for removal of methylene blue (MB) are reported. These composites were characterized with various techniques.

Citric Acid and Vitamin C as Coupling Agents for the Surface Coating of ZrO2 Nanoparticles and Their Behavior on the Optical, Mechanical, and Thermal Properties of Poly(vinyl alcohol) Nanocomposite Films

Abstract

A series of bio-nanocomposites (BNC)s were fabricated through solution casting method. At first, the surfaces of ZrO2 NPs were functionalized with citric acid and Vitamin C as green modifier agents.

Green and eco-friendly route for the synthesis of Ag@Vitamin B9-LDH hybrid and its chitosan nanocomposites

Abstract

Firstly, Ag nanoparticle (Ag-NP) was synthesised with environmentally-friendly and green media extracted from Rosmarinus officinalis plants. The structure of Ag-NP was confirmed with the absorption peak related to the Surface Plasmon Resonance at 432 nm through UV–Vis analysis.

Construction of crosslinked chitosan/nitrogen-doped graphene quantum dot nanocomposite for hydroxyapatite biomimetic mineralization

Abstract

Crosslinked Chitosan/nitrogen doped-graphene quantum dot nanocomposites (CCS/NGQD NC) with 10 wt% of glutaraldehyd as crosslinker were fabricated under ultrasonic cavitation. Structure and physicochemical properties of the prepared nanocomposites (NC) were systematically characterized by a number of techniques.

LDH-VB9-TiO2 and LDH-VB9-TiO2/crosslinked PVA nanocomposite prepared via facile and green technique and their photo-degradation application for methylene blue dye under ultraviolet illumination

Abstract

Vitamin B9 (VB9) as a biological molecule was used for the intercalation of MgAl-layered double hydroxide (LDH) which can increase the active sites and organic nature of LDH samples.
