Fully Bio‐Based Epoxy Thermoset Based on Epoxidized Linseed Oil and Tannic Acid

نویسندگان

چکیده

Increasing demand for bio-based epoxy thermoset alternatives has risen in the last few years. Epoxidized vegetable oils (EVO) have attracted significant attention due to their bio-based, unharmful nature and high availability. This study proposes a fully based on epoxidized linseed oil (ELO) tannic acid (TA). TA allows, with its degree of functionality aromatic structure as curing agent ELO, create polymer network glass transition temperature (Tg), stiffness, strength. A maximum Tg 146 °C, flexural modulus 2986 MPa, strength 72 MPa are obtained. The strong material properties TA/ELO expose potential substitute petrochemical-based resins high-performance applications.

Transesterification of epoxidized soybean oil to prepare epoxy methyl esters

Epoxidizedmethyl esters were prepared by the transesterification of epoxidized soybean oil (ESBO). The transesterification was complete in 10min at 50 ◦C without loss of the epoxide function. Epoxidized methyl esters represent a renewable substrate that is readily converted into surfactants, fuel additives, and other industrial products. The implementation of this reaction will increase the ava...

Preparation and Characterization of a Novel Biodegradable Epoxy Resin Modified with Epoxidized Oleic Acid

The goal of this research was to study the curing behavior and biodegradability DER 736 modified with epoxidized oleic acid. In this paper we demonstrate the efficient epoxidation of oleic acid with performic acid generated in situ from formic acid and hydrogen peroxide in the presence of H2SO4 as catalyst. The highest relative epoxy yield of 61% was achieved at 40 ͦC after 10 h. DER 736 modifie...
