Electrical properties of doping mesentery by carbon black for (ppad) Abstract:This paper included two parts , in the first part we can study general theoretical information about polymers and special information about (ppab) and carbon black and addition weighting percentages . In the second part we can study the electrical properties of the polymer (ppad) before and after we adding the carbon black and the effect of these additing on the electrical conductivity of (ppad ) Study showed effect of doping on the electrical properties of (ppad). The addition of carbon black to the matrix of (ppad) caused increase in electrical conductivity of (ppad) Chiang C .K. , et.al Lee R.H et.al 2008 1978 n ) Serin M. et.al 2006 , Li Chen , et.al 2000 p )Addamo M., et.al 2008 , Holloway J.H. and Billand D., 1983 Srivastava A.p. and Sinh H.C. 1989 Banimahd keiv M., et.al 2010 E N E R G Y d c d b c a b a Microstructure Microstructure Additives Skotheim T.A., 1986 Al chaim H.A.R, 1998 Skotheim T.A., 1986 MT Ketsen black EC ISAF M2/gm A0 ml/100mg 2 3 4 pH 5 235 (Ω.Cm)-1 1.7×10-9 ( Ω.Cm)-1 180(Ω.Cm)-1 SeF6 TeF6 n q δ= N × q × µ n q ………….(1) p-type n-type Mert-Germany Mert-Germany 2 3 gm 5% 4 6% 5 0.3% 6 0.02% 7 0.05% 8 0.13g/ml 9 130 0A 2 3 1 2 Al 1-2mm Al 10-50µm Al Al Amp. 2 5 7 11 14 17 21 25 28 Amp. 2 6 10 14 18 24 28 32 36 Volt. 5 10 20 30 40 50 60 70 80 Volt. 5 10 20 30 40 50 60 70 80 Amp.
