“…Despite of that, chemical treatment may have disadvantages on the cellulosic fibers if not properly utilized and strongly depends upon the treatment type, concentration, duration and fiber types themselves. This in order may lead to a performance deteriorations in the final composites [28,29]. For example, PP-wood composites did not show any significant variation in their mechanical properties when mercerized with 10% NaOH solution [30].…”

Facilitating finding low-cost renewable and sustainable environmental functional alternative materials for green products has been recently emphasized. Lignocellulosic materials are of such potential alternatives to enhance the modern cleaner production theme. In this work several structural parameters, reinforcement conditions and chemical treatments have been investigated to reveal their effects on the final desired mechanical performance of corn agro waste lignocellulosic / polyester composites for sustainable green products. Low-cost treatment solutions as sodium chloride, phosphoric and citric acids were considered for Mediterranean corn agro waste lignocellulosic fibers. Results have revealed that superior mechanical performance enhancements were occurred for the produced bio-composites. It was demonstrated that prepared composites were capable of enhancing the tensile strength as well as modulus for all types of treatment. About 157% tensile strength enhancement was achieved in case of 30wt. % fiber content when treated with phosphoric and citric acids. Moreover, sodium chloride treatment was capable of achieving 81 MPa for the 20wt. % fiber loading comparable to 54.7 MPa for the matrix. The modulus of elasticity property was also enhanced more than 600 % for the untreated fibers and sodium chloride treated ones. This obviously demonstrates the potential of such low-cost fiber/ low cost treatment synergy to fabricate potential green materials for sustainable industrial applications as well as enhance evaluating such materials from various technical stand points for the future sustainable cleaner production.

The ability of biodegradable materials to be miniaturized and degrade at specific rates when subjected to certain bacterium types and/or a given range of temperatures has led to a newly emerging technology: organic transient bioelectronics. In this work, the electrical characteristics of new natural composite materials are presented. Four types of natural lignocellulosic fibers were used with polypropylene: black pepper, sumac, pomegranate, and lemon. The composites were prepared as flat smooth sheets with thicknesses ∼1 mm. The dielectric constant and the ac conductivity of the prepared samples were determined for the frequency range of 1 KHz to 4 MH. All measurements were performed at room temperature and humidity utilizing parallel plate capacitor technique associated with high precision Hioki IM3536 LCR meter. The frequency response of the composites under study shows similar behavior to that of the pure sample but with various percentage increments. The dielectric constant shows that the consistent dispersion was highly affected by filler content specially at the low frequency side of the spectrum. The maximum recorded increment was around 55% for 30wt.% sumac samples at 1 KHz. The effect of larger filler loading concentration on the incremental change of the ac conductivity was more obvious at higher frequencies.
