Dataset for: Attachment of a Hydrophobically Modified Biopolymer at the Oil–Water Interface in the Treatment of Oil Spills

We measured the stability of crude oil droplets formed by chemical dispersants with the addition of a hydrophobically modified chitosan. Emulsions of crude oil in saline water were prepared using a combination of the biopolymer hydrophobically modified chitosan and the chemical dispersant Corexit 9500A. This dataset reports zeta potential, interfacial tension, percent transmittance, viscosity, elastic and viscous modulus for several ratios of Corexit to crude oil and biopolymer to Corexit. This dataset includes images and videos of the oil-in-water behavior when exposed to dispersants. Dataset supporting the publication Venkataraman et al. 2013 Attachment of Hydrophobically Modified Biopolymer at the Oil-Water Interface in the Treatment of Oil Spills, ACS Appl. Mater. Interfaces, 5 (9), 3572-3580, DOI: 10.1021/am303000v.本数据集测定了添加疏水改性壳聚糖（hydrophobically modified chitosan）后，化学分散剂所形成的原油液滴的稳定性。本数据集通过将生物聚合物疏水改性壳聚糖与化学分散剂科立捷9500A（Corexit 9500A）复配，制备了盐水中的原油乳液。本数据集记录了不同科立捷与原油配比、生物聚合物与科立捷配比下的Zeta电位（zeta potential）、界面张力（interfacial tension）、透光率（percent transmittance）、黏度（viscosity）以及弹性模量（elastic modulus）与黏性模量（viscous modulus）。本数据集还包含了水包油体系在分散剂作用下的行为图像与视频资料。本数据集支撑的发表论文为Venkataraman等人2013年发表于《ACS应用材料与界面》（ACS Appl.
