Development of new sustainable inorganic flame retardant additive system for Polyamide 6,6 with improved performance

A number of reported studies in the literature have shown that phosphorous compounds can act in both the condensed and the gaseous phases, resulting in highly efficient flame retardant properties. Recently, the use of inorganic compounds containing phosphorous to improve flame retardant properties of polymers has increased significantly, thus providing a complement to existing halogenated substances. Among the phosphorous-based compounds, inorganic phosphate glasses (P-glasses) display a wide range of desirable properties such as chemical durability, high thermal expansion, good electrical conductivity, optical clarity, biocompatibility and flame retardant properties. The objective of this project is to study the effect of special new P-glass compositions with varying glass transition temperatures on the processing conditions of polyamide 6,6 (PA6,6) and the final hybrid structure and flame retardancy (FR).

Synthesis of bioactive glass/POSS® based nanocomposites as an implant for fractured bone’ regeneration

The use of the traditional rigid metallic bone prostheses is associated with stress shielding. This occurs further to the removal of the stress carried by the prosthesis in the fracture region, leading to osteoporosis with decreased bone strength. The main objective of this project is to develop a biodegradable implant composite with sufficient mechanical support to the healing bone during the healing process, and able to regenerate natural tissue and release the ions necessary for bone’ healing before degrading..
