  • Patent number: 10400099
    Abstract: The present invention relates to a halogen-free epoxy resin composition, a prepreg, a laminate and a printed circuit board containing the same. The halogen-free epoxy resin composition comprises an epoxy resin and a curing agent. Taking the total equivalent amount of the epoxy groups in the epoxy resin as 1, the active groups in the curing agent which react with the epoxy groups have an equivalent amount of 0.5-0.95. By controlling the equivalent ratio of the epoxy groups in the epoxy resin to the active groups in the curing agent to be 0.5-0.95, the present invention ensures the Df value stability of prepregs under different curing temperature conditions while maintaining a low dielectric constant and a low dielectric loss.

    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.
