“…Raw CFP and SBS were tested independently for comparison. As observed, the CFP decomposition curve shows a weight loss stage at the range of 50-250 • C attributed to the beginning of thermal decomposition of keratin [26], a second one at the range of 250-400 • C consistent with the keratin denaturation and disulfide bonds breakdown, and finally, a residue (about 18%) at 1000 • C [20]. The SBS thermogram showed a single decomposition stage ranging from 400 to 500 • C, which is typical of this kind of material [20].…”

In the present work, the evaluation of chicken feather particles (CFP) and styrene-butadiene/chicken feather (SBS-CF) composites as modifiers for asphalt binder is presented. It is well known that elastomers are the best asphalt modifiers, because their thermoplastic behavior assists asphalts in improving the range of their mechanical properties at both low and high temperatures. Nowadays, the use of natural products and byproducts as fillers for polymer matrices has been a matter of research, and the field of asphalt modification is not the exception. Chicken feather particles (CFP) is a waste material whose main component is keratin, which offers remarkable properties. In the present work, CFP was used as a filler of a styrene-butadiene rubber matrix (SBS) with radial structure, to obtain a composite intended as an asphalt modifier. Besides, raw CFP was also tested as an asphalt modifier. Physical, thermal and rheological properties of the modified asphalts were evaluated in order to determine their degree of modification with respect to the original asphalt. The results show that the addition of raw CFP improves some physical properties as penetration and decreases the phase separation; furthermore, the asphalt modified with CFP displayed similar rheological properties to those shown by the asphalt modified with SBS, while some other properties resulted in being even better, like the phase separation, with the advantage that the CFP comes from a natural waste product.

“…Figure 5 shows the FTIR spectra for SBS and SBS-PSP 10 phr composite. The main functional groups of SBS are present at 3005, 2916, 2844, 1800 and 1639 cm -1 due to unsaturated carbons, stretching of methyl and methylene groups and aromatic rings, respectively [18,26]. In SBS-PSP composites spectra, it is evident the peak at 1742 cm -1 , which is attributed to C=O groups, as well as the signal at 3690 cm -1 from -OH groups and the peak at 1163 cm -1 associated to aliphatic ethers.…”

“…This kind of material may be arranged in a variety of structures, such as linear, radial or multi-radial block copolymers [1]. There are several studies of composite materials based on SBS reinforced with natural or animal waste materials [18][19][20][21] finding that its properties can be modified with the addition of this kind of fillers.…”

Nowadays, the use of agricultural wastes is a high impact research area, due the fact that this kind of materials can provide some interesting properties to a polymer matrix. Among these materials, the seed shell are materials with no industrial applications, so it is necessary to find a use in the aim to avoid the pollution. The Styrene-butadiene copolymer (SBS) is a wide used material due it thermoplastic behavior. In present work, the inclusion of two different species of seed shell particles: (jatropha curcas seed particles (JCSP) and pistachio (PSP)) into a Styrene-butadiene copolymer (SBS) and their effect on the thermal behavior of the resulting composites have been studied. The composites were prepared by melting fussion process at different concentrations ranging from 2 to 10 phr (parts per hounded of resin). The obtained composites were characterized by means of Thermogravimetric analysis (TGA), Dynamic Mechanical Analysis (DMA) and infrared Spectroscopy (FTIR).

Awareness of the environmental impact of using polymeric materials obtained from petroleum is causing increased interest in sustainable materials manufacturing. Here, we present the elaboration of fully biobased materials using an aromatic epoxy resin matrix coming from wood biomass and two natural by-products, namely, keratin from chicken feathers and lignin. In situ FTIR kinetic studies show that the two natural fillers increase the conversion of the epoxide during cross-linking. This result, together with DSC studies, proves the chemical interactions between the keratin or lignin and the epoxide network. Up to 30% of these natural components could be reacted and incorporated into the epoxide with good compatibility. The thermomechanical properties of the elaborated materials are comparable to those of commercial ones.
