“…4 -7 Recently, the incorporation of lignocellulosic materials in biodegradable matrices has become the subject of considerable research. Shibata et al 8 and Avella et al 9 studied the mechanical properties of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) composites reinforced with short abaca and wheat-straw fibers, respectively. Dufresne et al 10 evaluated the effect of residual lignocellulosic flour from spruce and ground olive stone in composites based on poly(3-hydroxybutyrate-co-3-hydroxyvalerate).…”

ABSTRACT:The aliphatic polyester Bionolle 3020 was combined with lignocellulosic fibers, namely, flax, hemp, and wood, to produce biodegradable composite materials. The effect of two fiber surface treatments, acetylation and propionylation, and the addition of maleic anhydride (MA)-grafted Bionolle 3001 as a compatibilizer on the fiber/matrix interfacial adhesion was studied. The compatibilizer was synthesized through a MA grafting reaction in the presence of dicumyl peroxide as an initiator. The composites' mechanical properties, water absorption, fracture morphology (scanning electron microscopy), and biodegradation were evaluated. Both the fiber treatments and the compatibilizer incorporation significantly improved the composites' tensile strength, whereas an important reduction in the water absorption was found with the addition of treated fibers. Moreover, fiber incorporation into the matrix increased its biodegradation rate.

“…In general, the melting point for the size of 1 mm is higher than 60 mesh as well as on the cross linking while the decomposition temperature differences are not significant, it is caused by increasing adhesion between the front crumb rubber between the polypropylene matrix and SIR-20 compound [21]. The rise degree of temperature can be caused by the interaction of the hydroxyl group of molecules between the filler and the carbonyl group from materials compatibilizer resulting hydrogen bonds can decrease the polymer mobility.…”

Having been researched the development of thermoplastic elastomer material of polypropylene and natural rubber SIR-20 compound with Crumb Rubber as the filler. Reinforced polypropylene with size 60 mesh with 1 mm, and the composition of the Crumb rubber (30, 40, and 50) wt%. Observed mechanical properties are tensile strength, fracture elongation, Young's modulus, tear strength and impact strength. Thermal properties are analyzed by DSC and DTA/TGA. It is acquired that for the size of 60 mesh crumb rubber tensile strength, fracture elongation, Young's modulus, tear strength and impact strength are bigger than 1mm size. The addition of 60 mesh crumb rubber increases but it decreases by adding of 50 weight%. While for crumb rubber 1 mm tensile strength, fracture elongation, tear strength and impact strength decreas. Based on analysis of DSC that the addition of crumb rubber does not make a difference boiling point significantly between samples containing crumb rubber and polypropylene Analysis TGA/DTA to an increase in enthalpy and decomposition temperature with the addition of crumb rubber used and thermal stability. AbstrakPengaruh Ukuran dan Komposisi Serbuk Ban Bekas sebagai Filler dengan Kompatibeliser PP-g-MA pada Campuran Polipropilena dan Kompon SIR-20 terhadap Sifat Mekanik dan Termal. Telah diteliti pengembangan bahan termoplastik elastomer dari polipropilena dan kompon karet alam SIR-20 dengan serbuk ban bekas sebagai bahan pengisi. Polipropilena yang diperkuat dengan serbuk ban bekas dengan ukuran 60 mesh 1 mm, dan komposisi serbuk ban bekas (30, 40, dan 50) %berat. Sifat mekanik yang diamati adalah kekuatan tarik,perpanjangan putus, Modulus Young, kekuatan sobek, dan kekuatan impact. Sifat termal dianalisis dengan DSC dan DTA/TGA.Dari hasil penelitian diperoleh bahwa untuk ukuran serbuk ban bekas 60 mesh kekuatan tarik, perpanjangan putus, modulus Young, kekuatan sobek, dan kekuatan impact lebih besar dibanding ukuran 1 mm. Penambahan serbuk ban bekas 60 mesh mengalami peningkatan namun mengalami penurunan pada penambahan 50 % berat. Sedangkan untuk ukuran serbuk ban bekas 1 mm kekuatan tarik, perpanjangan putus, kekuatan sobek, dan kekuatan impact mengalami penurunan. Dari analisis DSC diperoleh bahwa dengan penambahan serbuk ban bekas tidak menghasilkan perbedaan titik didih yang signifikan antara sampel yang mengandung serbuk ban bekas dan polipropilena. analisis TGA/DTA adanya peningkatan enthalpy dan suhu dekomposisi dengan adanya penambahan serbuk ban bekas dan terjadi stabilitas termal.

“…The thermal softening temperatures of The crystallization enthalpy of the control film was 9.0cal/g, calculated from the area of the exothermic peak. Avella et al reported that the value of crystallization enthalpy is 10.5cal/g for P(HB-co-HV) with 5% of 3-hydroxyvalerate units [14]. The crystallization enthalpies were 8.6cal/g and 3.8cal/g for the composite films with 10wt% and 20wt% of lignophenol, respectively.…”

Novel lignin-based polymers, lignophenols, have been derived from native lignins through the phase-separation system composed of phenol derivatives and conce ntrated acid. The molecular weight of lignophenol was controlled from ca.7400 to ca.520, using the intramolecular switching function under the alkaline condition. By the blending of the biopolyester [poly (3-hydroxybutyrate)] with butylhydroxyanisole (BHA), triacetin and lignophenol 2nd derivative, the elongation ratios of the resulting films became 5, 5 and 20 times higher, respectively, compared with the control film without additives. For the composite films with BHA and triacetin, the shrinkages and the weight losses were observed with increasing temperature, due to the evaporation of additives. On the other hand, for the composite film with lignophenol 2nd derivative, no shrinkage was observed, and the thermogravimetric profiles were almost compatible with that of the control film. The DSC analysis indicated that the crystallization enthalpies of biopolyester-lignophenols films decreased with increasing contents of lignophenols.
