B -- SYNTHESIS AND EXAMINATION OF THE DIELECTRIC PERMITTIVITY OF POLYMER COMPOSITES FOR USE AS STANDARD REFERENCE DIELECTRICS IN MICROELECTRICS. SOL 43SBNB067069 DUE 071400 POC Diane Loeb (301) 975-6399, FAX (301) 975-7732, or e-mail: dloeb@nist.gov WEB: NIST Contracts Homepage, http://www.nist.gov/admin/od/contract/contract.htm. E-MAIL: NIST Contracts Office, Contract@nist.gov. The National Institute of Standards and Technology (NIST) intends to negotiate on a sole source basis with Dr. Roman Popielarz of Gaithersburg, MD to explore the applicability of polymer composite films as reference dielectric materials for high speed electrics. This study is pursuant to understanding physics that determine the broadband dielectric permittivity of polymer-ceramic formulations. Model composites are to be designed and synthesized to evaluate the effect of polymer matrix and ceramic dispersions on microwave permittivity of the composite films. Services are to be performed at NIST Gaithersburg, MD. The polymer dielectric composite films for microwave applications are newly explored formulations for which prior data does not exist. The proposed work requires very comprehensive and specialized knowledge of chemistry, polymer science and photoprocessing technology, which is a unique combination of expertise of Dr. Roman Popielarz. He will use this expertise and the unique experimental techniques that he developed during his last year assignment as a NIST guest researcher. See Note 26. No solicitation package will be issued. The intended period of performance is one year. The anticipated award date will be fifteen to twenty days after the date of this notice. Posted 06/29/00 (W-SN470033). (0181)
