“…In addition, our data gleaned from chitosan microspheres supported that either [bis(2-methylallyl) (1,5-cyclooctadienne) ruthenium (II)] or ruthenium ions exhibited an excellent ability to degrade dyes in the presence of an ecological oxidant [8]. More importantly, to extend applications, several approaches have shed the light on the blending of chitosan with other natural or synthetic polymers [9][10][11][12][13][14][15]. For example, Kim and Min [15] have developed a composite fiber of polyacrylonitrile (PAN) and chitosan by spinning polymer mixture and the obtained composite showed a much higher amount of uptake for acid dye than that of either powdery chitosan or activated carbon.…”

In this paper, we report the modification of polyamide sample (PA) with different contents of chitosan (CS) using citric acid (CA) as a cross-linker [PA-CA-CS]. New materials were confirmed to be formed in PA using FT-IR spectrum. It is also checked in terms of the change in thermal stability event and decomposition behavior in thermogravimetry through TG-DTA instruments. Then, the ability of unmodified and modified supports was tested for the adsorption of two reactive dyes i.e. Cibacron Brilliant Yellow 3G-P and Cibacron Blue P-3R. Sorption experiments were performed under varying several experimental conditions such as pH, contact time, initial dye concentration, and temperature. The isotherm and kinetic models were undertaken to assess the dye removal mechanism. The applicability of Langmuir, Freundlich, DubininRadushkevich, and Temkin equations was checked and data were fitted using Langmuir model. The second-order equation was shown to fit the adsorption kinetics. Data gleaned from both thermodynamic results and modeling data indicate that the adsorption follows a chemical and exothermic process.

“…The presence of the chitosan contributes to the formation of a stronger polymer network (Bonilla et al 2014). When studying the mechanical properties of cellulose films, Shih et al (2009) also found that the addition of chitosan improved the mechanical properties of the resulting cellulose/chitosan films.…”

The film-forming ability of bagasse hemicellulose and its potential for packaging were investigated in terms of its mechanical and water vapor barrier properties. The films were prepared under various hemicellulose concentrations, chitosan/glycerol amounts (based on the amount of hemicellulose), and temperatures. These were subsequently evaluated by measurement of their mechanical and water vapor barrier properties. Bagasse hemicellulose-based films with higher tensile strengths were obtained at higher hemicellulose concentrations. Scanning electron microscope images showed that the bagasse hemicellulose-based films did not have pores less than one micron in size, suggesting compatibility between the hemicelluloses and the other components present in the films. Moreover, the tensile strength, elongation, and water vapor barrier of the film increased by approximately 124%, 115%, and 48%, respectively, when the drying temperature increased from 25 to 55 °C. These results indicate that the bagasse hemicellulose can be used as part of the raw material for films with good barrier and mechanical properties.

“…Plant-derived cellulose is already being used extensively in the paper and textile industries. [6][7][8] Methylcellulose (MC), a biodegradable polymer, is a modified type of cellulose, which is the most abundant biopolymer in nature. It is well known and of interest to be used as environment-friendly products, especially as coating or mulching film, because of its large availability, low cost, and easy processability.…”

International audienceMethylcellulose (MC) films were prepared by casting from its 1% aqueous solution containing 0.5% vegetable oil, 0.25% glycerol, and 0.025% Tween®80. Poly(caprolactone) (PCL) films were prepared by compression molding from its granules. Biodegradable composite films were fabricated using MC film as reinforcing agent and PCL as the matrix material by compression molding. One layer of MC film was reinforced with two layers of PCL films. The MC content in the composites was varied from 10 to 50% by weight. Mechanical, barrier, and degradation properties of PCL, MC, and composite films were evaluated. The values of puncture strength (PS), puncture deformation (PD), viscoelasticity (Y) coefficient, and water vapor permeability (WVP) of the composites (50% MC content) were found to be 124.3 N/mm, 3.2 mm, 31%, and 2.6 g*mm/m2*day*kPa, respectively. Oxygen transmission rate (OTR) of PCL, MC, and composites (50% MC) were found to be 175, 25, 22 cc/m2/d, respectively, which indicated that composite films showed significantly lower OTR than PCL films. Degradation tests of the composite films (50% MC) were performed for 6 weeks in aqueous medium (at 25°C), and it was found that composites lost its mass slowly with time. After 6 weeks, mass and PS of the composites were decreased to 13.4 and 12%, respectively. Composite interface was studied by scanning electron microscopy (SEM). The MC film had good adhesion with PCL matrix during compression molding and suggested strong interface of the composite system. SEM image after 6 weeks of degradation showed some openings in the interface and revealed slow degradation of the MC films. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 201
