“…The data provided evidence of the partial structure of the polymer sample. Recently, bio-polymers such as lignin, cellulose and human hair were subjected to the TOF-SIMS analysis to study their structures (Saito et al 2005a(Saito et al , 2005bFardim and Holmbom 2005;Matsushita et al 2008Matsushita et al , 2012Kojima et al 2011). Figure 5 shows the mass spectra of the electropolymerized polymers using ferulic acid, ferulic acid-(methoxy-d3), ferulic acid with the CH2Cl2/CD3OD solvent medium, and caffeic acid.…”

Electropolymerization was carried out in order to obtain a bio-based polymer by a simple procedure. Ferulic acid, a component of gramineous plants, was selected for this purpose. A thin polymer film was produced in an organic solvent medium (i.e., CH2Cl2/methanol (4:1 v/v) in the presence of 0.2 M LiClO4), whereas it was not obtained in a totally aqueous medium (0.2 M NaOH). Scanning electron microscopic analysis showed that the polymer film had a porous lamellar structure of ~10 μm thickness. Most of the carboxyl groups remained, and IR spectroscopy and time-of-flight secondary ion mass spectrometry (TOF-SIMS) analyses revealed that oquinones existed in the polymer film. After electropolymerization, caffeic acid, sinapic acid, 3,6-bis(4-hydroxy-3-methoxyphenyl)tetrahydrofuro [3,4-c]furan-1,4-dione (1), and 4,4'-dihydroxy-3,3'-dimethoxy-β,β'-bicinnamic acid (2) were detected in the organic reaction medium; this suggested that demethylation, methoxyl group addition, and radical coupling reactions occurred at the electrode surface.

“…Photooxidative behavior and effect of chain extender length in polyurethane on photooxidative stability have also been reported Zia, Barikani, Zuber, Bhatti, & Islam-ud-Din, 2008). Surface morphology of starch (Matsushita et al, 2008), cellulose (Yokota, Kitaoka, & Wariishi, 2008), and chitin-humic acid (Santosa, Siswanta, Sudiono, & Utarianingrum, 2008) have also been investigated and well documented. XRD studies and surface characteristics of UV-irradiated and non-irradiated chitin-based polyurethane elastomers have also been presented elsewhere Zia, Barikani, Khalid, Honarkar, & Ehsan-ulHaq, 2009;Zia, Barikani, Zuber, Bhatti, & Barmar, 2009e, 2009f).…”

“…Surface morphology of starch [21], cellulose [22,23] and chitinhumic acid [24] has also been investigated and well documented. No reference is still available on the study of the surface characteristics of polyurethane extended with blends of chitin/1,4-butane diol blends.…”
