“…For all samples, an initial and small loss peak can be observed at the temperature of 83 °C due to the loss of water remaining in the material after the drying process. The second mass loss occurred at temperatures of 316 °C, 313 °C and 322 °C for the F2, F1 and F4 samples, respectively, corresponding to the degradation of hemicelluloses and pectin [42] . The weight losses at temperatures of 354 °C, 368 °C and 370 °C (samples F4, F1 and F2, respectively) correspond to the decomposition of cellulose and lignin [43,44] .…”

SbstractThe modification of lignocellulosic fibers can enhance their interaction with other materials and alkaline hydrogen peroxide (AHP) is a reagent widely used to promote such modification. This work aimed to modify oat hulls fibers by reactive extrusion using AHP (7 g 100 g -1 of hulls). The modified oat hulls displayed performances comparable to those observed by other researchers using conventional AHP method (without extrusion). The AHP treated oat hulls showed increased luminosity compared to the extruded ones. Fourier transform infrared spectroscopy showed differences between the modified and unmodified structures. The removal of surface compounds resulted in a more open morphology, with greater surface area and greater porosity. Reactive extrusion can be an alternative method for fiber modification with several advantages, such as short processing time and no wastewater generation.

“…In this regard, PCL can be functionalized with reactive polar groups, such as epoxide (Kim et al, 2001;Sugih et al, 2009), or anhydride (Wu, 2003;Arbelaiz et al, 2006) able to react with the -OH groups of starch backbone. Laurienzo et al (2006) adopted a rather innovative method to functionalize PCL, with simultaneous melt grafting of maleic anhydride (MA) and glycidyl methacrylate (GMA) in a batch mixer and in presence of peroxide as initiator.…”

The use of a modified poly(ε-caprolactone) (gPCL) to enhance polymer miscibility in films based on thermoplastic starch (S) and poly(ε-caprolactone) is reported. PCL was functionalized by grafting with maleic anyhdride (MA) and/or glycidyl methacrylate (GMA) by reactive blending in a batch mixer. gPCL based materials were analysed in terms of their grafting degree, structural and thermal properties. Blends based on starch and PCL (wt. ratio 80:20) with including gPCL (0, 2.5 and 5wt.%), as a compatibilizer, were obtained by extrusion and compression moulding, and their structural, thermal, mechanical and barrier properties were investigated. Blends containing gPCL evidenced better interfacial adhesion between starch and PCL domains, as deduced from both structural (XRD, FTIR, SEM) and bulk properties (DSC, TGA). Moreover, grafted PCL-based compatibilizers greatly improved functional properties of S-PCL blend films, as pointed out from mechanical performance and higher barrier properties, valuable to meet the food packaging requirements.
