Over the past few decades, there has been an increasing demand for bio-based polymers and resins in industrial applications, due to their potential lower cost and environmental impact compared with petroleum-based counterparts. The present research concerns the synthesis of epoxidized palm oil acrylate (EPOLA) from an epoxidized palm oil product (EPOP) as environmentally friendly material. EPOP...

A 3D-printing process is presented for the manufacturing of modular aerogel/acrylate bricks that are fully scalable and customizable potential applications in thermal insulation. The use tools conjunction with a sol-gel method aerogel synthesis circumvents geometric limitations fabrication large size load bearing articles. In this study, two-component manufactured from low conductivity aerogels...

An efficient method to improve the mechanical performance of a commercially available photocure resin is described wherein modified with mixture cycloaliphatic epoxy and an anhydride curing agent. Photocured samples are thermally treated in subsequent step cure obtain interpenetrated polymer network (IPN) also complete reaction acrylate monomers remaining from photocure. The latter accomplished...

In this work, a novel dual-curing procedure has been developed. It is combination of first radical UV-initiated thiol-(meth)acrylate reaction, followed by second thermal thiol-epoxy step catalysed base. Since (meth)acrylates can lead to homopolymerization mechanism, the amount thiol be optimized reach cross-linked materials with Tgs above room temperature and good mechanical performance. should...

The effect of semiconducting tungsten disulfide (WS2) nanoparticles (NPs), functionalized by either methacryloxy, glycidyl, vinyl, or amino silanes, has been studied in photocuring acrylate and epoxy resins (the latter photocured according to a cationic mechanism). curing time, degree (DC), thermal effects, mechanical properties the radiation-cured were investigated. X-ray photoelectron spectro...

Compared to amines as coinitiators applied in photopolymerization, benzodioxole derivatives exhibit similar reactivity but less yellowing and lower toxicity. In this paper, a series of unimolecular type II photoinitiators, containing coumarins chromophores benzodioxoles coinitiators, were synthesized. The substituents with different electron donating/withdrawing abilities designed for systemati...
