“…These results are in agreement with those obtained by Zakaria et al (30) who utilized chitosan as paper coating. In our case, the acrylic acid has occupied the pores and some of them adhered only on the surface.…”

“…It can indicate the resistance to rupture of paper materials (29) .The burst strength is highly related to the strength of fiber bonding in paper making. This is due to the penetration of coating binder into the fibers arrangement and the resemblance of the chemical structure between binder and cellulose fibers which has higher compatibility (30) .…”

URRENTLY, styrene acrylate copolymers have highly been employed in paper coating application. In sequence to contribute to the green environment approach, different styrene acrylate copolymers with different pigment percentages were formulated and applied on recycled brown base paper in order to determine the most efficient coating. The study also investigated the applicability of Egyptian ground calcium carbonates in paper coating as an alternative of the traditional imported kaolin pigment. The effect of such binders on mechanical properties; water absorbency "Cobb60"; air permeability of paper; gloss and printability of coated paper was explored. The water absorption of coated papers was 30gm/m 2 compared with 35gm/m 2 for the commercial one. This means that ink consumption can be decreased by ≈30% in concert with the possibility of usage of low viscous ink. Gloss of coated papers was upgraded to more than double that of base ones. The burst strength; ring crush and the tensile strength for the coated papers were simultaneously improved compared with the commercial ones. The printability of coated papers was as well superior to the commercial one; this can evidently reduce the economical cost of the printing process.

“…Owning to its fascinating properties such as biodegradability, biocompatibility and nontoxic nature, chitosan can be used in many fields including cosmetics, textile industry, foods processing, agriculture and water treatment (Cheba 2011). This basic polysaccharide also has been investigated in the manufacture of paper (Zakaria et al 2015) and stabilizer in synthesis of metal nanoparticles for biomedical applications (Ahmad et al 2014;Akmaz et al 2013). Recently, studies on the graft copolymerization of chitosan with various vinyl monomers have been extensively conducted to explore fully their high potential.…”

Ammonium persulfate (APS)-initiated grafting of methacrylamide (MAM) onto chitosan was successfully prepared for the first time by free radical mechanism. Both chitosan and chitosan-graft-poly(methacrylamide) (chitosan-g-PMAM) were characterized using Fourier transform infrared spectroscopy (FTIR), solid state 13 C NMR, thermogravimetric analysis (TGA), differential scanning calorimetry (DSC) and scanning electron microscopy (SEM). Important factors affecting graft copolymerization such as reaction time, temperature and concentrations of APS, MAM and chitosan were investigated and optimized to obtain maximum grafting parameters. The optimum values for grafting percentage and yield of graft copolymerization were achieved under the following conditions: chitosan (1 g), MAM (4 g), APS (0.6 g), time reaction (4 h) and temperature (70ºC).

In this work, proton exchange membranes (PEMs) based on chitosan (CS) and cellulose (CL) have been prepared using a solution-casting technique with sulfosuccinic acid (SSA) as an ionic cross linker. The characteristics of these CS-CL biocomposite membranes were studied using scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), electrochemical impedance spectroscopy (EIS) in addition to the measurement of the water uptake rate (WUR) and the ion exchange capacity (IEC). The results indicate that the amount of SSA used in this study played a significant role in the proton conduction of the membrane. The proton conductivity of a cross-linked CS-CL membrane was on the order of 10 -5 S cm -1 , which is greater than the proton conductivity of a pure CS membrane.Keywords: proton exchange membranes, chitosan, cellulose, biocomposite, membrane Abstrak Dalam kajian ini, membran penukaran proton (PEM) berasaskan kitosan (CS) dan selulosa (CL) telah disediakan dengan menggunakan teknik tuangan larutan bersama dengan asid sulfosusinik (SSA) yang berfungsi sebagai pemaut silang ion. Sifat membran biokomposit CS-CL ini dikaji menggunakan mikroskopik pengimbas elektron (SEM), spektroskopi inframerah transformasi Fourier (FTIR), spektrometer elektrokimia impedans (EIS) sebagai tambahan kepada pengukuran kadar penyerapan air (WUR) dan kapasiti penukaran ion (IEC). Keputusan menunjukkan bahawa jumlah SSA digunakan dalam kajian ini memainkan peranan penting dalam pengangkutan proton di dalam membran. Kekonduksian proton untuk CS-CL bertaut silang membran yang diperoleh adalah di dalam lingkungan 10 -5 S cm -1 , iaitu lebih tinggi berbanding dengan kekonduksian proton membran CS tulen.
