A methylene-blue-sensitized polymer blend of polyvinyl alcohol and polyacrylic acid is fabricated and tested for holographic recording. It was found to have good characteristics such as high sensitivity, storage stability, ease of fabrication, and environmental stability. Optimization of the ratio of polyvinyl alcohol/polyacrylic acid, the sensitizer concentration, pH, energy, diffraction effic...

Cellulose nanocrystals (CNCs) have shown remarkable application prospects due to their outstanding chemical and physical properties. In this research, cellulose were isolated from grass waste using alkali, bleaching acid hydrolysis treatments further used as nanofiller in polyvinyl alcohol (PVA) films. The valorisation of the waste, an eco-friendly sustainable low-cost precursor yields ~23.3% C...

In this paper, the aqueous copolymer dispersions of methyl (meth)acrylate-grafted poly(vinyl alcohol) are in situ synthesized and studied as a promising platform for deposition thin films with advanced applications. A series varied structure composition obtained at mild reaction conditions by carrying out redox polymerization different monomer-to-PVA ratio initiator concentration. The colloidal...

A LiDAR system consists of a Q-switched fiber laser that emits light pulses to measure the distance from target. We have experimentally demonstrated passively erbium-doped (EDFL) by employing graphene saturable absorber (SA). The SA was prepared dipping polyvinyl alcohol (PVA) thin film into solution. Once fabricated, it can be placed in cavity perform and is operating at 1558.92 nm. shortest p...

In the present study, pure (PVA) polymer film and films reinforced with CdCl2.H2O salt various values of weight ratio ((3,7,11, 15) wt%) were prepared use solution casting method. The effects upon apparent porosity composite (PVA-CdCl2.H2O) was investigated, practical results revealed that decreases when salt’s increases. on true density studied, it found increases increase in added salt. effec...

In this study, we prepared composites made from polyvinyl alcohol (PVA), sodium alginate (SA), curcumin (Cur), and polydopamine (PD). The film-forming properties of the were researched for potential wound-healing applications. structures polymer blends studied by FTIR spectroscopy microscopic observations (AFM SEM). mechanical measured using a Zwick Roell testing machine. It was observed that f...
