  • Publication number: 20150005407
    Abstract: Shape memory polymers (SMP) based on poly vinyl alcohol (PVA) in the presence of 2-carboxyethyl acrylate oligomers (CEA), multi-wall carbon nanotubes (MWCNTs) and cross linked by ionizing radiation were investigated. Chemical crosslinking by glutaraldehyde for PVA in the presence of CEA and MWCNTs was also studied. Radiation cross linked SMP exhibits good temperature responsive shape memory behavior as demonstrated by thermal properties of radiation investigated by dynamic mechanical analysis. Transition temperature at Tan ? of radiation cross linked SMP decreased significantly by 6 and 13° C. due to addition of MWCNTs. The developed SMP exhibited promising shape memory behavior of radiation cross linked SMP for biomedical applications between temperatures range of Tan ?. Results on the gel fraction revealed significant reduction in swelling and increase in gelation due to chemical cross linking with glutaraldehyde. The radiation cross linked SMP reached 100% gelation at an irradiation dose of 50 kGy.

  • Patent number: 8663722
    Abstract: The present disclosure relates to a process for removal of pesticide residues from aqueous solutions and food products by ionizing radiation. Standard pesticides concentrations recognized by international organizations as maximum residues limit (MRLs) were used as the targeted concentrations in both aqueous solutions and food products. Commercially known pesticides and recommended irradiation doses by International Atomic Energy Agency (IAEA) were selected for this investigation. Aqueous solutions and food products fortified with pesticide residues were subjected to selected doses of ionizing radiation. Radiation-induced removal of pesticide residues is generally greater in aqueous solutions than in food products. Ionizing radiation can reduce the residues of pirimiphos-methyl in potatoes, grapes and dates; malathion and cypermethrin in grapes to below MRLs at the recommended irradiation doses.

  • Patent number: 8263674
    Abstract: An eco friendly radiation cross-linked composition is described that demonstrates excellent resistance to fire and high temperature along with good mechanical properties. The composition which is based on a blend of EVA with a LLDPE, is free of monomer such as vinyl co-agent for radiation cross-linking. The halogen free flame retardant composition is a mixture of 20 to 90% by weight of magnesium hydroxide (powder A) and 90% to 20% of powder B. Preferably the powder B is a double salt of magnesium carbonate and calcium carbonate and the magnesium hydroxide has a specific surface treatment. In addition, 0.5 to 5 parts of flame retardancy agents are selected from talc, zinc borate or molybdate derivative. The chemicals used here reduce toxicity in the environment and do not release toxic chemicals to air and soil during fire. The flame retardant cross-linked polyolefin composition is particularly useful for insulating wires and cables.
