Green Synthesis of Polymer Composites/Nanocomposites Using Vegetable Oil

Abstract

Vegetable triglycerides are among the first renewable resources exploited by man primarily in coating applications because their unsaturated varieties polymerize as thin films in the presence of atmospheric oxygen. Nowadays, use of the vegetable oils is spotlight of the chemical industries and as they are using these as a renewable platform for further ability. In order to overcome disadvantages such as poor mechanical properties of polymers from renewable resources, or to offset the high price of synthetic biodegradable polymers, various blends and composites have been developed over the last decade. The progress of blends from three kinds of polymers from renewable resources (1) natural polymers, such as starch, protein, and cellulose; (2) synthetic polymers from natural monomers, such as polylactic acid; and (3) polymers from microbial fermentation. In this chapter we have discussed about the different types of polymer composites obtained from the vegetable oil and applications of the polymer composites.

New Colorless and Transparent Poly(ether imide) Derived from a Biobased Plant Oil (Anethole): Synthesis and Properties

“…Measurement. The 1 H NMR, 19 F NMR, and 13 C NMR spectra were determined on a JEOL 400YH instrument. The intrinsic viscosities ([η]) were measured in DMSO at 25.00 ± 0.01 °C by an Ubbelhode viscometer via extrapolation toward zero concentration.…”

“…The solution of reprecipitated polyimide in DMSO had inherent viscosity of 1.46 dL/g at 25 °C. The chemical structure of the polymer was confirmed by 1 H, 19 F NMR spectra and elemental analysis, with detailed data listed in the Experiment section and Supporting Information. The 1 H NMR spectrum of polymer exhibited a similar characteristic peak with compound 2, and 19 F NMR showed the F signal of decafluorobiphenyl units appearing at −138.00 and −153.61 ppm.…”

Polyimide PI-I displayed good solubility in aprotic solvent such as N,N-dimethyl-acetamide (DMAc) or 1-methyl-2-pyrrolidinone (NMP).…”

“…Recently, the development of biomass-derived polymers has aroused growing research interests. Utilization of natural biomass resources as raw materials to prepare polymers not only can reduce the dependence on petrochemical resources for establishing a sustainable low-carbon society − but also can obtain novel high performance/functional materials with unique properties, which usually cannot be easily accessed from petroleum-derived chemicals. − Molecular design based on biomass compounds can be a promising approach to find some monomers with novel structures tailored for high heat-resistant CPIs.…”
