“…Approximately 3-5% of cotton fibers is waste linters. The amount of linter produced in the world is about 2.5 million tones, considering the 42 million tons of cotton linter produced in 2010 18,19 . One of the main difficulties when dealing with natural composites is the adhesion between fibres and matrices, mainly due to the hydrophilic and hydrophobic characteristics showed by the fibres and the polymers, respectively 20 .…”

This study evaluated the effect of adding poly (ethylene methyl acrylate) (EMA) and cotton linter (CL) on the properties of recycled poly (ethylene terephthalate) (PET rec ). For this, PET rec /EMA blend and PET rec /EMA/CL composite were developed. In order to improve the interfacial adhesion and the properties of these materials, ethylene/methyl acrylate/glycidyl methacrylate terpolymer (EMA-GMA) and polyethylene-grafted maleic anhydride (PE-g-MAH) were added. The rheological results showed that the addition of EMA increased and the addition of 1 wt% of CL reduced the viscosity. The morphological analysis of the non-compatibilized blend and composite showed poor interfacial adhesion. Polymer blends with 2 and 6 wt% of EMA had better mechanical properties, since these formulations have the smallest average particle diameter of 0.58 and 1.00 µm, respectively. The mechanical testing of composites showed a material with higher maximum strength and elasticity modulus than polymer blend when analyzed at the same EMA phase concentration. The use of EMA-GMA was effective in reducing the size of particles of the EMA in the blend.

“…The quality of the cellulose fibres mainly depends www.scienceasia.org on the NaOH concentration and reaction temperature 25 ; hence corn peel was treated with 3% (w/v) NaOH at 90-100°C for 2 h 24 . Water pollution during bleaching is also a concern; hence hydrogen peroxide was used instead of chlorine.…”

Cellulose fibres were isolated from corn peel agricultural waste using NaOH extraction and converted to carboxymethyl cellulose (CMC) by carboxymethylation using monochloroacetic acid (MCA) in alkaline conditions. A Box-Behnken statistical design was used to evaluate the parameters (soaking time with NaOH solution, soaking time with MCA solution, and reaction time with MCA) affecting the degree of substitution (DS) of CMC. Optimization was carried out by using the response surface method. The optimized conditions for CMC production with a maximal DS of 0.90 were soaking with NaOH for 118 min, followed by soaking with MCA for 6.5 h, and reaction with MCA at 60°C for 84 min. FTIR and XRD confirmed the successful carboxymethylation. This work demonstrates the feasibility of using corn peel agricultural waste as an alternative raw material for the production of CMC with high DS.

“…Response surface method was previously employed to optimize preparation of biocomposites based on poly(lactic acid) and durian peel cellulose [21], preparation of carboxymethyl cellulose [22], and preparation of amaranth flour plasticized with glycerol and sorbitol [8]. Concentration of gelatin (A), glycerol (B) and citric acid (C) acted as independent variables, while the responses were tensile strength (T) and elongation at break (ε).…”
