|Title:||Static SIMS of polyacetylene: the effect of chain unsaturation||Authors:||Wee, A.T.S.
|Issue Date:||Nov-1991||Citation:||Wee, A.T.S.,Huan, C.H.A.,Gopalakrishnan, R.,Tan, K.L.,Kang, E.T.,Neoh, K.G.,Shirakawa, H. (1991-11). Static SIMS of polyacetylene: the effect of chain unsaturation. Synthetic Metals 45 (2) : 227-234. ScholarBank@NUS Repository.||Abstract:||The static secondary ion mass spectra of high density cis-polyacetylene films are reported. Due to its highly reactive nature, the spectra of the as-received film surface are characteristic of that of a saturated polymer. After light Ar+ sputtering, the negative ion spectrum for polyacetylene shows a distinct fingerprint with a C2 -:C2H- ratio greater than one. Comparison with the spectra of polyethylene and other saturated polymers reveals that this is characteristics of a conjugated main chain. Hence, a criterion for determining the degree of chain unsaturation for a polymer surface is proposed using the C2 -:C2H- ratio. This shows great promise in the application of SIMS to the study of reactive conjugated polymer surfaces. © 1991.||Source Title:||Synthetic Metals||URI:||http://scholarbank.nus.edu.sg/handle/10635/91711||ISSN:||03796779|
