New hybrid materials based on double‐functionalized linseed oil and halloysite
Abstract:A series of hybrid systems which combine double‐functionalized linseed oil (methacrylated epoxidized linseed oil) and 2 types of functionalized halloysite (methacrylated halloysite and epoxidized halloysite) was designed in the current study. The curing of the new formulated oil‐clay mixtures was performed via 2 different mechanisms under the influence of the temperature: free‐radical and anionic polymerization. The effect of the functionalized clay tubes against the oil‐based macromonomer reactivity, representing the focus of this study, was monitored by differential scanning calorimetry and Fourier transform infrared spectrometry, concluding that both types of halloysite nanotubes (HNTs) exhibit significant influence on the building of methacrylate/epoxy networks. The effect of the HNTs on the methacrylated epoxidized linseed oil network properties was studied by dynamic mechanical analysis and thermogravimetric analysis, and the morphology of the synthesized hybrids was investigated by scanning electron microscopy. The results suggested that the designed oil‐based hybrid performance is determined by the presence of the both HNT molecules.
