RAFT Terminated Hyperbranched Functionalized Nano Rice Husk Powder / EPDM Nanocomposite for Biomedical Applications

Modified nanosize rice husk powder (i.e. mod.nRHP; mod.nRHP-MA-RAFT-H)/ethylene propylene diene monomer (EPDM) nanocomposite was prepared by solvent casting method. The surface of nano rice husk (n-RHP) was treated with maleic anhydride (MA) to yield n-RHP-MA, then, aliphatic hyperbranched polyester...

Description
Summary:	Modified nanosize rice husk powder (i.e. mod.nRHP; mod.nRHP-MA-RAFT-H)/ethylene propylene diene monomer (EPDM) nanocomposite was prepared by solvent casting method. The surface of nano rice husk (n-RHP) was treated with maleic anhydride (MA) to yield n-RHP-MA, then, aliphatic hyperbranched polyester (H) was end capped with RAFT agent to obtain H-RAFT. Afterward, H-RAFT-was successfully anchored onto nRHP-MA via RAFT polymerization technique to afford nRHP-MA-RAFT-H (mod.nRHP). The mechanical and thermal properties were studied for nRHP-MA-RAFT-H (mod.nRHP)/EPDM nanocomposite with different loadings of mod.nRHP. The cytotoxicity activities of the prepared mod.nRHP/EPDM nanocomposites were investigated toward human cell lines in vitro.
