Boron containing polymers

Boron clusters (exp. Carboranes)

There are three main properties for using boron in polymers. One of them is empty p orbital and the other one is neutron capturing. Thirth property is that it can react with oxygen at elvated temperature and produce B₂O₃ char. Eren research group have two main research fields in boron application. One of the medicine for its nuclear properties and the other one is composite for its flame retardant behavior. Boron neutron capture therapy (BNCT) is based on the nuclear reaction that occurs. When boron-I0 is irradiated with low-energy thermal neutrons to yield alpha particles. There are two main properties during the application in cancer treatment. One of the is transfer of B-10 atom to the selectively to cancer cells. Secondly, a high fluence of neutrons is to be delivered to the tumor. Boron containing polymers also show flame retardant properties. So, they can be used in high performance polymers, fibers and composites

Carboran bearing polymers

The research presented in this project focuses on the development of novel functional hybrid organic-inorganic architectures containing chemically-tethered icosohedral carboranes. The motivation behind this work was to understand and overcome the challenges associated with the incorporation of inorganic boron clusters into a variety of well-defined polymeric architectures bearing phosphorus functionality. This task was critical for the advancement of scientific understanding, as well as the improvement and implementation of novel hybrid materials towards technological applications.

Boron nitride based composites

The present work focuses on the investigation of the thermal and dielectric properties of hexagonal boron nitride (BN) containing ROMP (Ring Opening Metathesis Polymerization) based composites. The effects of BN and its content on the dielectric properties, and thermal resistance of composites, are systematically investigated and discussed. The resultant composites possess the high electrical break over voltages. While all of the ROMP based films exhibit low ε′ value in a wide frequency range, In the case of the composite with 20% BN and poly(bromooxanorbornene-co-cyclooctadiene) displays very low dielectric constants in around 1.5 up to 1 MHz at 20oC. This value is significantly lower than that of common polymer dielectrics. Considering this extremely low ε′ and small Tan δ values of composites, it can be said that ROMP homopolymer and ROMP-BN composite films highly satisfy these requirements at a wide range of frequency and temperature.
