“…During the last decade, an increasing amount of research has been published involving keratin fibers from chicken feather with synthetic polymers, such as grafting with polymethylmethacrylate [19,20] and polyhydroxyethylmethacrylate [21]; composites with polyethylene [22,23], polypropylene [24][25][26], polymethylmethacrylate [27], polyurethane [28] and phenol-formaldehyde [29], among others [18], however there are only few related to keratin fibers and biopolymers [30,31].…”

Abstract:The performance as reinforcement of a fibrillar protein such as feather keratin fiber over a biopolymeric matrix composed of polysaccharides was evaluated in this paper. Three different kinds of keratin reinforcement were used: short and long biofibers and rachis particles. These were added separately at 5, 10, 15 and 20 wt% to the chitosan-starch matrix and the composites were processed by a casting/solvent evaporation method. The morphological characteristics, mechanical and thermal properties of the matrix and composites were studied by scanning electron microscopy, thermogravimetric analysis, differential scanning calorimetry and dynamic mechanical analysis. The thermal results indicated that the addition of keratin enhanced the thermal stability of the composites compared to pure matrix. This was corroborated with dynamic mechanical analysis as the results revealed that the storage modulus of the composites increased with respect to the pure matrix. The morphology, evaluated by scanning electron microscopy, indicated a uniform dispersion of keratin in the chitosan-starch matrix as a result of good compatibility between these biopolymers, also corroborated by FTIR. These results demonstrate that chicken feathers can be useful to obtain novel keratin reinforcements and develop new green composites providing better properties, than the original biopolymer matrix.

“…According to Cheng et al (2009);Abdul Khalil et al, (2011), moisture absorption leads to swelling and degradation at fiber matrix interface which results in poor mechanical properties and dimensional instability. Thus, the water ingress capacity of the composites was evaluated to find out whether they could be used in structural applications.…”

The present work demonstrates the fabrication and properties study of Vinyl ester i.e. Bisphenol-A glycidyldimethacrylate (BisGMA) composites hybridized with 2-hydroxyethyl acrylate (HEA-10% w/w) grafted jute fiber and aqueous NaOH (5% w/w) treated coir pith used in various proportions and to characterize thereof. The mechanical and dynamic mechanical properties were measured in dependence of treated & untreated fiber as well as filler content. Composite with HEA grafted jute fiber and coir pith (15 wt%) exhibited maximum improvement in the above mentioned properties. Thermogravimetric analysis indicated the thermal stability of composites due to effective hybridization. The corrosive and water ingress properties of the composites were found to be negligible contributing to longer durability of the panels in moist and corrosive conditions.

“…[30][31][32][33] Figure 5 shows strain-stress curves of PLLA and PLLA/L50-blended (95:5 wt%) films. The initial elastic moduli of PLLA and the blended films were 1.8 and 1.6 GPa, respectively, indicating that the compliance was slightly improved by the addition of the branched polymer.…”

“…For all samples, clear transitions at T g and T m were observed in the second heating scan. On the basis of the enthalpy of fusion of 100% crystallized PLLA (93.7 J g À1 ), [28][29][30] the crystallinity (X c ) of the branched polymer was calculated from the melting endotherm of the sample. Figure 2 relates the feed ratio of LLA to castor oil, T g , T m and X c .…”

Branched poly(lactic acid) was synthesized by ring-opening polymerization of lactide using castor oil as an initiator. The structure of the branched polymer was confirmed by 1 H nuclear magnetic resonance spectroscopy. The molecular weight of the branched polymer increased linearly as a function of the feed ratio of lactide and castor oil. The thermal properties of the branched polymer were evaluated using differential scanning calorimetry and were compared with those of linear poly(L-lactic acid) (PLLA). A blended film of the branched polymer and PLLA was prepared by hot pressing at 175 1C. A content of 5 wt% of the branched polymer was sufficient to increase the strain at break. Thermomechanical analysis of the blended film revealed a decrease in the initial elastic modulus with addition of the branched polymer. The thermal and dynamic mechanical properties of the film were examined, and the crystalline morphology of the film was examined by polarized light microscopy.
