Hexagonal boron nitride nanosheets (BNNSs) possess ultimate thermal and chemical stabilities and mechanical strengths. However, the unmodified BNNSs are hydrophobic and insoluble in water, which hinders their use in many technological areas requiring aqueous compatibility. In this work, h-BN was treated with molten citric acid to produce aqueous dispersible boron nitride sheets (ca-BNNSs). The ...

The demand for robust hydrogels in pharmaceutical, biomedical, and industrial applications has motivated intense research efforts in these wet polymeric materials. Recent advances have resulted in different strategies for creating highly stretchable polymeric hydrogels, including sliding-ring gels (SR gels), nanocomposite gels (NC gels), doublenetwork gels (DN gels), macromolecular microsphere ...

Graphene based sulfonated polyvinyl alcohol (PVA) hydrogel was synthesized and its performance as nanocomposite gel polymer electrolyte investigated for application in quasi solid-state flexible supercapacitors. Hydrothermally reduced graphene (HRG) through hydrothermal reduction of oxide (GO). Sulfonated PVA (SPVA) with predetermined quantities HRG to obtain electrolytes coded SPVA-HRG-x (x = ...

A novel biohybrid hydrogel nanocomposite made of natural polymer carrageenan and gelatin protein were developed. The silver nanoparticles prepared using the as reduction capping agent. Here, Ag/Carrageenan was combined with glutaraldehyde having a cross-link role in order to create nanocomposite. manufactured composite performances anaylised by UV–visible spectroscopy, Fourier Transform infrare...

Global water pollution by organic dyes and metals may be solved adsorption. In particular, hydrogel adsorbents display unique advantages due to their three-dimensional porous structure. Here, a new type of self-healing hydrogels based on boronate amide bonds were prepared. The precursor polymer, 2-aminophenylboronic acid-modified polyacrylic acid (PAA-2APBA), was firstly synthesized amidation, ...
