Collagen was extracted from the skin of pigs, and blended with sodium alginate, starch, and sodium carboxymethyl cellulose. Food packaging films were obtained by crosslinking the blend with glutaraldehyde. Fourier transform infrared spectroscopy (FT-IR), SEM and TGA analyses were used to characterize the resulting films. A strong hydrogen bonding was detected between the composite film molecule...

Experimental Section: Precursor preparation TiO2 mesoscopic film was prepared by doctor-blading of commercially available anatase paste (Dyesol, 18NR-T) on cleaned FTO glass, then slowly heated up to 450°C and kept for 30 min to form the porous mesoscopic film. After, there are three steps for the quaternary precursor to be insitu deposited and coated onto the mesoscopic TiO2 film: 1. 100 mL 0....

The present work, describes electrochemical preparation of a novel cadmium pentacyanonitrosylferrate (CdPCNF) film as a Prussian Blue analogous on the glassy carbon (GC) electrode from a solution of 5 mM CdCl2 and 5 mM Na2[Fe(CN)5NO]. The effect of experimental conditions such as pH and composition of electrodeposition solution on the peak current of the modified electrode and its stability wer...

Microand nano-particle charge is one of the main factors determining the physical stability of both emulsions and suspensions and can be quantified by measuring their so called “zeta potential”. When all the particles have a large either negative or positive zeta potential value, they will repel each other and, as a consequence, the suspension becomes stable. By contrast, whether the zeta poten...

Polym. Adv g liquid processed polymer deposition method for the film preparation of functional polymers in photo-electronic devices. In this report, the results on the IJP of a fluorenebased electroluminescent polymer, poly(9,9-dihexylfluorene-alt-2,5-dioctyloxybenzene) (PF6OC8), from a piezoelectric droplet generator are presented. The polymer film thickness has been found to show an approxima...

Almost general poly(vinyl alcohol) (PVA) films were prepared by the processing of a PVA solution. For the first time, a novel poly(vinyl alcohol) (PVA) film was prepared by the saponification of a poly(vinyl acetate) (PVAc) film in a heterogenous medium. Under the same saponification conditions, the influence of saponification time on the degree of saponification (DS) was studied for the prepar...

       This article describes the preparation and analysis of nano hydroxyapatite (HA) films on stainless steel 316L through sol-gel technique. The process started with preparation of a nitrate and phosphate sol. After aging the sol for 24 h at room temperature a SS316 substrate was dip-coated and heat-treated at 350 to 450 °C for different times in air. The coating phase and structure on subs...
