“…Definitely, lower pyrolysis temperatures are more desirable because they aim to reduce the running cost along with obtaining higher amounts of the char. [19,21,22]. It seems that filler's ability to transfer stress from the matrix was not sufficient; therefore, further addition of the char (290 C) decreased the tensile strength of PLA biocomposites.…”

This article aims on the fabrication of cost-effective polylactic acid (PLA) biocomposites using kudzu biomass derivatives as new filler. In this way, it has been realized that pretreatment of the filler was an essential requirement. We demonstrated thermal pyrolysis process that targeted to extraction and isolation of all extractable and unnecessary compounds such as intracellular water and bio-oil from the biomass. Also, to further improve the compatibility of the filler with PLA, noncatalytic thermal esterification reactions of kudzu after thermal pyrolysis (called char) were carried out as second pretreatment stage in the presence of phthalic anhydride. Kudzu derivatives obtained from either first or second pretreatment reactions were melt-blended with PLA in various rates. The blends were then compression molded into dumbbell specimens. Physicomechanical properties of the prepared biocomposites were evaluated using several analytical techniques. It was found that biocomposites containing treated biomass had higher values of physicomechanical properties than untreated ones. The final rate of filler to PLA with acceptable properties was set up to 50%. Obviously, the cost of PLA can be reduced using higher rates of low-cost filler on a finished-product basis. Extracted valuable compounds from biomass via thermal pyrolysis could be another benefit of the process. POLYM. ENG. SCI., 55:340-348, 2015.

“…There have been numerous studies on chitosan, such as chitosan blended with natural polymer (Garcia et al 2006;Senna et al 2012;Zhai et al 2004), synthetic polymer (Salmah and Azieyanti 2011;Salmah et al , 2012a, and modified chitosan (Ambri et al 2013;Beppu et al 2007;Rutnakornpituk et al 2006). However, there is a lack of literature on the development of natural filler in chitosan biocomposite films.…”

Chitosan/Corn Cob Biocomposite Films by Cross-linking with Glutaraldehyde

Corn cob (CC) was used as a filler in chitosan (CS) biopolymer films. The effect of glutaraldehyde (GLA) as a crosslinking agent was studied in an effort to improve the properties of CS/CC biocomposite films prepared via solvent casting. The tensile strength and elongation at break values decreased, but the modulus of elasticity increased with CC content. However, the tensile properties of CS/CC biocomposite films improved when modified with GLA. The Fourier transform infrared (FTIR) results indicated the presence of imine bonds (C=N) and ethylenic groups due to the cross-linking reaction between CS and GLA. The thermal stability of CS/CC biocomposite films reduced with increasing CC content. The modification of CS/CC with GLA enhanced the thermal stability of the biocomposite films. Moreover, the wettability and adhesion of the CC-CS system were enhanced by modification with GLA, as demonstrated by a morphological study. The crosslinking agent glutaraldehyde positively affected the tensile strength, modulus of elasticity, and thermal stability of the biocomposite films.

“…Polypropylene is a commodity polymer that is using in broad applications in the packaging, textile, automobile, and furniture industries because of its excellent processability, recyclability and low cost [12,13]. There is still need to understand the behavior of the thermoplastic materials with anatural organic filler such as wood flours [14][15][16][17]. This study evaluated the thermal acadj@garmian.edu.krd Conference Paper (July, 2017)…”

A research paper focuses on investigations of the improvements on chemical and thermal, and mechanical properties of polypropylene (PP) by adding cellulose microcrystalline fillers (CMC). The CMC powder was used as reinforcement in pure PP with various weight percentages 5, 10 and 20 % respectively. The melt mixing process was used to prepare (PP/ CMC) composites. The structural changes of PP/CMC composites were investigated by Fourier transform infrared (FTIR) spectra. The results of the Thermogravimetric analysis (TGA) exhibited that the higher addition of 20% CMC into the pure PP slightly improved both the residue yields and thermal stability. The tensile strength of 20% CMC into pure PP was slightly increased and elongation reduced, compared with pure PP.
