Organic‐Inorganic Hybrids from Renewable Plant Oils and Clay

Abstract

This study deals with the preparation and properties of a new class of organic-inorganic hybrids from renewable resources. The hybrids were synthesized by an acid-catalyzed curing of epoxidized triglycerides in the presence of an organophilic montmorillonite (a modified clay). The mechanical properties were improved by the incorporation of clay in the oil-based polymer matrix. The reinforcement effect due to the addition of clay was confirmed by dynamic viscoelasticity analysis. The hybrids showed relatively high thermal stability. The co-curing of epoxidized soybean and linseed oils in the presence of clay produced hybrids with controlled mechanical and coating properties. The barrier property of the hybrid towards water vapor was superior to that of the oil polymer. The development of the present hybrids consisting of inexpensive renewable resources, triglyceride and clay is expected to contribute to global sustainability.

Green Nanocomposites from Renewable Plant Oils and Polyhedral Oligomeric Silsesquioxanes

“…These epoxy compounds from renewable resources possess high potential as a starting material for bio-based thermosetting plastics [35][36][37][38]. The composites of plant oil-based network polymers from epoxidized plant oils and inorganic substances were developed [39][40][41]. The acid-catalyzed curing of epoxidized plant oils in the presence of an organophilic montmorillonite produced the triglyceride-clay composites with homogeneous structure, in which silicate layers of the clay were intercalated and randomly distributed in the polymer matrix.…”

Bio-Based Nanocomposites Composed of Photo-Cured Soybean-Based Resins and Supramolecular Hydroxystearic Acid Nanofibers

“…Regarding ESO-based composites, the biocomposites with kenaf, kayocell, flax, and hemp etc. have been reported by some groups Tran et al, 2006;Warth et al, 1997), and the nanocomposites with organically modified layered silicates have been reported by other groups Uyama et al, 2004;Liu et al, 2005;Song et al, 2006). Also, regarding AESO-based composites, there had been some literatures on the biocomposites of a mixture of AESO and styrene with natural fiber mats made of flax, cellulose, pulp and hemp (O′Donell et al, 2004;Khot et al, 2001), and the nanocomposites of AESO and organically modified montmorillonite (Ǻkesson et al, 2010;Lu et al, 2004).…”

Antimicrobial and Thermal Properties of Coating Systems Modified with ZnO Nanoparticle and its Hybrid Forms: (A Review)

“…Coating systems such as polyesteramides, polyetheramides, polyesteramide-urethanes are synthesized from plant base polyol platforms as exemplified in Scheme 1 8,10 . The synthesized pristine organic coating products however shows limited thermal, corrosion, antimicrobial, rigidity, and chemical characteristic properties required in structural applications [12][13][14] . It is in the light of this, that researchers are incorporating designed nanoparticles within the polymeric matrix of pristine coatings in order to reinforce the characteristic properties of the polymer composite thereby, creating innovative solutions in the area of optics, electronics, biomedical and material science.…”
