Biobased Epoxy Resin by Electrochemical Modification of

A biobased epoxy resin was prepared from tall oil fatty acids (TOFAs), a byproduct of the pulping industry. As free carboxylic acids compromise resin stability, TOFA was subjected to non-Kolbe decarboxylation to give alkenes upon loss of CO2. Thereby, the degree of unsaturation is significantly increased. This electrosynthetic protocol using an undivided cell setup and inexpensive graphite

Recent Progress in Polymer

Epoxy resin-based polymer concrete with good strength has excellent properties, but its cost is very high, which restricts its wide applications [27, 28]. Compared with epoxy, epoxy-urethane acryl [ 29, 30 ] is reactive and does not require solvent evaporation or special equipment for the recovery of solvent, and thus, environmental pollution and impact on the workers are minimized.

Choosing the Right Lignin to Fully Replace Bisphenol A in

Lignin can be incorporated into epoxy resin via three different methods: 1) blending with petroleum‐based epoxy resin, 24, 25 2) modification of lignin followed by epoxidation, 23, 26-30 and 3) epoxidation of unmodified lignin. 16, 31, 32 Although many studies have

Eugenol

In particular, in the case of the epoxy resin with P2 (), the nature of the epoxy coating surface is altered from hydrophilic (θ 90 ) to hydrophobic (θ ≥ 90 ) in the presence of additive P2. The increased water-repellency of the epoxy coatings doped with P1 or P2 can be attributed to the patterned surface morphology induced by the eugenol-polysiloxane additives. 47,48

Synthesis of bio

The bio-based epoxy resins for coating application were synthesized from gallic acid (GA) in various molar ratios with epichlorohydrin (ECH). The reaction was carried out in the presence of sodium hydroxide (NaOH) and phase-transfer catalyst tetrabutylammonium bromide. The reaction progress rate at various molar ratios as 1:8, 1:12, and 1:16 with respect to time was monitored by calculating
