“…Applications of nanotechnology include improved barrier, mechanical and antimicrobial properties, as well as the incorporation of nanosensors for traceability and the monitoring the condition of foodstuffs during transport and storage (Harrington, 2009). In recent years a lot of effort has been aimed at developing new biobased polymer containing films and nanocomposites which can act as barrier materials in packaging applications (Arora & Padua, 2010;Bae, Park, Darby, Kimmel, & Whiteside, 2009;Lagarón & Fendler, 2009;Maksimov, Lagzdins, Lilichenko, & Plume, 2009;Mangiacapra, Gorrasi, Sorrentino, & Vittoria, 2006;Napierała & Nowotarska, 2006;Plackett et al, 2006;Vartiainen et al, 2010).…”

“…The authors observed partial exfoliation and better mechanical properties for bentonite/polyamide PNC [11] and vermiculite/PP PNC [12]. Improvement of clay dispersion and the PNC properties were also reported in montmorillonite/pectin PNC prepared with ball milling [13].…”

“…During the functionalization of polyolefins via melt mixing, it is generally agreed that for isotatic polypropylene, the dominant reaction is chain scission [24]. However, Rengarajan et al [25] showed by 13 C NMR analysis that the grafted maleic anhydride moieties can form possible crosslinks between PP chains, explaining such increase of viscosity. The rate of increase changes with the P3150 content and the stability is reached later for high content.…”

The preparation of exfoliated polymer nanocomposites (PNC) in nonpolar system is still preoccupying researchers in the domain. The ball milling coupled with melt‐compounding was used for the preparation of polypropylene/montmorillonite PNC to evaluate the potential of ball milling in the improvement of clay dispersion. Different approaches were used for doing a preliminary ball milling of clay with or without coupling agent and of all components prior to melt‐compounding. The microstructure as well as the rheological and the dynamic mechanical behaviors of the PNC compounds were characterized. The best improvements in clay dispersion were obtained by ball milling clay in the presence of other components to reduce particle agglomeration. The rheological behavior of the compounds confirmed their microstructure. The thermomechanical properties of PNC showed an enhancement in the storage modulus in the glassy and the rubbery states, independent of their microstructure. POLYM. ENG.

“…TGA, incelenen maddelerin termokimyasal dönüşüm esnasında yarı kantitatif olarak ısıl bozunma süreçlerinin anlaşılmasını sağlamaktadır [64]. Tüm pektin örneklerinin sıcaklıkla bozunma eğrilerinin benzer şekilli olduğu ve sonuçların literatürde bulunan diğer çalışmalarda da bildirilen [65][66][67][68][69][70] bir şekilde termal bozulmaya uğramakta, daha sonra yan grupların ve halkadaki karbonların dekarboksilasyonu ile gaz çıkışı ve katı "char" (odun kömürüne benzer katı kalıntı) oluşumu meydana gelmektedir. Üçüncü bölgede (400-600°C) katı charın termal parçalanması ve daha sıkı bir şekilde birleşmesi ile daha yavaş kütle kaybı meydana gelmektedir [68,70].…”

Comparison and Characterization of Pectins Obtained From Citrus Peels ABSTRACTPectin is a polysaccharide that is widely used in food industry. It is a linear polymer of α(1,4) linked D-galacturonic acid units with varying degrees of methylation. In the present study, the extraction characterization and comparison of some physicochemical, structural and thermal properties of pectins from lemon, mandarin, orange and grapefruit citrus peels were determined. For the production of pectin, citrus peels were extracted in a solution of citric acid (pH 1) and extracted pectins were precipitated with ethanol. All pectins were high methoxylated while lemon and orange peel pectin had better gel strength and liquid holding capacity than the others. Orange peel pectin had higher thermal stability while lemon peel and grapefruit pectins had a more organized structure than the other pectins.
