“…The pendant carbon-carbon double bonds in the polyesters showed high reactivity during the radial polymerization [21,22]. To the best of our knowledge, unsaturated polyester has been widely applied in coatings industry due to its high gloss, hardness, impact resistance as well as fast cure characteristics [27][28][29]. In this paper, several bio-based unsaturated polyesters were synthesized from itaconic acid and different diols (ethylene glycol (EG), 1,4-butanediol (BDO) and 1,6-hexandiol (HDO)) to produce bio-based waterborne UV-curable coatings.…”

This paper investigates the possibility of improving the mechanical and thermal properties of epoxy and unsaturated polyester toughened epoxy resins through the dispersion of octadecyl ammonium ion exchanged montmorillonite (organoclay) through exfoliated mechanism. The nanocomposites prepared are characterized for their structural change and studied for their crystallite size, mechanical, thermal and water absorption (hydrophilicity) properties. The mechanical data indicates significant improvement in the flexural and tensile properties over the neat epoxy and UP epoxy matrix according to the percentage content of orga noclay. The thermal behavior too shows noticeable enhancement in glass transition temperature T g and high thermal stability. Hydrophilicity of all the composites decreases irrespective of the concentration of organo clay on the epoxy and UP epoxy matrices. The homogeneous morphology of epoxy and UP toughened epoxy nanocomposite hybrid systems is ascertained using scanning electron microscope (SEM). X ray results point out that the cetyl ammonium modified clay filled composites exhibited the exfoliated structure.

“…To enhance the performance of the thermoset matrix, modifications of epoxy with polyester matrix combinations are being investigated [5,6]. Unsaturated polyester resins possess very good mechanical, thermal and corrosion-resistant properties, and are also simpler and more economical than epoxy.…”

The aim of this paper is to investigate the effect of the ratio of fillers, such as multiwalled carbon nanotubes (MWCNTs) and graphene nanoplatelets (GNPs), as well as different matrix stiffnesses, on the tensile strength of epoxy/polyester material. These fillers are added to epoxy/polyester solutions in various ratios and mixed well before moulding. Experimental specimens are then made by means of the hot press process and utilizing the same curing and post-curing conditions. To investigate the effect of the matrix stiffness on the mechanical property reinforcement role of MWCNTs and GNPs in the resulting nanocomposites, the variations in the mixture ratios of the epoxy/polyester blend and hardener are considered. The results show that the tensile strength of epoxy/polyester material increases its maximum value by approximately 86.3% with the addition of MWCNTs at a ratio of 1%, and increases to 86.8% with the addition of a mere 0.2% ratio of GNPs. The morphologies of the fractured surfaces of the resulting nanocomposites are observed by a scanning electron microscope (SEM). It is expected that the experimental results will lead to the offering of low-cost, high-strength materials for applications in the automobile industry and the manufacturing of household products.
