Synthesis and Characterization of AN-g-SOY for Sustainable Polymer Composites

Abstract

Biobased polymers are rapidly emerging as one of the alternatives to synthetic polymers based materials due to the rising environmental awareness and augmented consumption of nondegradable polymers. In the present work, surface characteristics of biorenewable soy flour (SOY) were tailored via free radical induced graft copolymerization of acrylonitrile (AN) to develop the novel materials for multifunctional applications. A number of reaction parameters were optimized to get the maximum percentage of grafting. The synthesized acrylonitrile grafted soy (AN-g-SOY) copolymers were characterized using Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and thermogravimetric analysis (TGA). Polymer composites were also prepared using the pristine SOY/ AN-g-SOY as the reinforcement and poly (methyl methacrylate) (PMMA) as the matrix. It has been perceived from the dynamic mechanical analysis results that acrylonitrile grafted SOY exhibit significantly enhanced storage modulus compared to the pristine SOY reinforced polymer composites.

Self-healing polymer nanocomposite materials: A review

“…Different kinds of polymer-based materials have been used for a number of applications due to their inherent characteristics including light weight, copious availability, flexibility, easy processing, lightness, and tailoring ability to name a few [57][58][59][60]. However, compared to metals and ceramics many of these materials exhibit poor mechanical properties, such as lower modulus and strength [58,61]. Research has shown that incorporation of nanomaterials significantly affects different properties of polymers including mechanical/ physical properties [62][63][64].…”

Dispersion and Property Enhancements in Polyolefin/Soy Flour Biocomposites Prepared via Melt Extrusion Followed by Solid‐State Shear Pulverization

“…There are numerous reports on soy‐based plastics with properties inferior to commercial elastomers . Recently, studies have focused on SF as green filler for biocomposites . Among these, there are only three studies focusing on the production and mechanical properties of polyolefin/SF composites in the refereed literature .…”

“…[26][27][28][29][30] Recently, studies have focused on SF as green filler for biocomposites. [31][32][33][34][35][36][37][38][39] Among these, there are only three studies focusing on the production and mechanical properties of polyolefin/SF composites in the refereed literature. [37][38][39] Sailaja et al [38] reported the effects of added coupling agent for SF and polypropylene (PP) and plasticizer for the SF component on the properties of PP/SF composites that were prepared by melt mixing (MM) at 210 8C.…”

Synthesis and application of hyperbranched poly(urethane‐urea) finishing agent with amino groups

“…However, hyperbranched polyurethane also has a few inefficiencies, such as poor mechanical properties including tensile modulus and low electrical conductivity that limit to address many avant-garde applications. 18,19 Although hyperbranched polyurethanes makes some properties worse, they have other excellent functions. In this study, hyperbranched polymer is used to increase the hydrophilic groups in PU, so as to improve the sanitary properties of leather.…”
