Abstract:

In this study individual halloysite nanotubes (HNTs) pre-loaded with Tween 80 surfactant were coated with a thin layer of long chain hydrocarbon wax (Paraffin wax, C20 – C40) with a high melting point. In addition, there was an extensive characterization of the morphology of Pristine halloysite nanotubes (HNTs), Tween 80 loaded halloysite nanotubes (S-HNTs) and Waxcoated, surfactant-loaded halloysite nanotubes. This dataset supports the publication: Farinmade, A., Ojo, O. F., Trout, J., He, J., John, V., Blake, D. A., … Bose, A. (2019). Targeted and Stimulus-Responsive Delivery of Surfactant to the Oil-Water Interface for Applications in Oil Spill Remediation. ACS Applied Materials & Interfaces. doi:10.1021/acsami.9b17254.

Purpose:

To show a technique to achieve stimuli responsive delivery of surfactants to the oil-water interface using clay nanotubes as cargo. This study investigates an aqueous based surfactant delivery system whereby surfactant release is triggered by contact with oil.

Figure 1b: Schematic showing the procedures for loading halloysites with surfactants and coating with wax as well as a photograph of the final products.
          
Figure 2(a-f): Scanning electron Microscopy images of bare HNTs, S-HNTs and WS-HNTs. SEM imaging was carried out using a Hitachi S-4800 Field emission scanning electron microscope operated at 3kV at a 3mm working distance. The samples were dispersed in ethanol and dropped on a sample holder followed by carbon coating to improve imaging by dissipating charging artifacts.
          
Figure 3(a-c): Transmission electron Microscopy of bare HNTs, S-HNTs and WS-HNTs. TEM imaging was carried out using an FEI G2 F30 Tecnai transmission electron microscope operated at 300 kV at room temperature. The samples were briefly dispersed in ethanol and dropped on the carbon-coated copper TEM grid and allowed to dry off prior to imaging.
          
Figure 3d (I and II): Contact Angle Measurement for bare HNTs and Wax coated HNTs. Each particulate sample (Pristine HNT and W-HNT) was compacted in a pellet die and pressed into a 13 mm disk pellet with about 1 mm thickness using a hydraulic press (Carver Laboratory Press). The contact angle was measured by placing the sample pellet in a goniometer (Ramé-Hart, model 250) and a 5 μL water droplet was dispensed on the sample using an automatic Ramé-Hart dispenser. Following equilibration, the three-phase contact angle was measured by DROPimage Advanced Software.
          
Figure 4a: Thermogravimetric analysis (TGA) of bare HNTs, S-HNTs and WS-HNTs. To determine the weight percent of surfactant loading and a wax coating, thermogravimetric analysis was performed using a TA instrument TGA Q500 thermogravimetric analyzer, operated at 5^o^C/min from 26^o^C to 720^o^C in a nitrogen environment.
          
Figure 4b: Tween 80 release kinetics from S-HNTs and WS-HNTs. The concentration of Tween 80 surfactant released in saline water was analyzed using the cobalt thiocyanate active substances (CTAS) UV-Vis Spectroscopy technique for determining Tween 80 in part per million (ppm) concentration. A UV-vis spectrophotometer (Shimadzu UV-1700) was used to measure the absorbance of the chloroform phase containing the cobalt thiocyanate−polyethoxylate complex at 620 nm. The concentration of Tween 80 for each sample analyzed was then extrapolated from an absorbance vs. concentration calibration curve of known concentrations of Tween 80.
          
Figure 5a: Time-dependent interfacial tension measurements. Interfacial tension was measured using the pendant drop technique on a standard goniometer (Ramé-Hart, model 250). 1mg/ml of particle suspension was prepared in saline water at room temperature. 20 μL of the suspension containing particles was drawn from the vial with a flat tip needle by an automatic Ramé-Hart dispenser. The needle was then plunged into a glass cuvette containing 5 ml of dodecane (oil phase) and 15 μL of the WS-HNT particles dispersed in water was injected. Drop shape analysis (DROPimage Advanced software) was used to determine the change in water-dodecane interfacial tension over time
          
Figure 5b: Emulsion droplet optical microscopy. Aliquots of the prepared dodecane in water emulsion were pipetted onto a glass slide for imaging under a Nikon eclipse LV100 optical microscope. The droplet size analysis was done using the ImageJ (open source) graphic analysis software and the average droplet size obtained from a distribution of 200 droplets
          
Figure 6(a-f): Cryo- Scanning electron Microscopy images of emulsions formed by W-HNTs and WS-HNTs. Cryo-SEM was employed to characterize the dodecane-water emulsions using a Hitachi S-4800 Field Emission Scanning Electron Microscope operated at 3 kV. To prepare the emulsion samples for imaging, small aliquots of the dodecane in water emulsion stabilized by W-HNT or WS-HNT were vitrified using liquid nitrogen. The frozen emulsion sample was then fractured at -130^o^C with the aid of a cold flat-edged knife followed by sublimation at -95^o^C for 10 minutes to expose droplets that are clearly imaged
          
Figure S1: X-ray Diffraction (XRD) patterns for Pristine HNTs, S-HNTs and WS-HNTs. X-ray powder diffraction (XRD) was carried out on a Siemens D500 X-ray diffractometer, using Cu Kα radiation at 1.54 Å, to determine the crystalline properties of bare HNTs, S-HNTs and WS-HNTs
          
Figure S2: Fourier Transform Infrared spectroscopy spectra of Pristine HNTs, S-HNTs and WS-HNTs. Fourier Transform Infra-Red (FTIR) spectroscopy was carried out using a Thermo Nicolet Nexus 670 FTIR spectrometer. For the FTIR analysis, each particulate sample was imbibed into Potassium bromide (KBr) powder and pressed into a thin transparent pellet prior to FTIR analysis
          
Figure S3: Proof of Tween 80 encapsulation by wax coating. The concentration of Tween 80 surfactant released in saline water was analyzed using the cobalt thiocyanate active substances (CTAS) UV-Vis Spectroscopy technique for determining Tween 80 in part per million (ppm) concentration. A UV-vis spectrophotometer (Shimadzu UV-1700) was used to measure the absorbance of the chloroform phase containing the cobalt thiocyanate−polyethoxylate complex at 620 nm. The concentration of Tween 80 for each sample analyzed was then extrapolated from an absorbance vs. concentration calibration curve of known concentrations of Tween 80
          
Figure S4: Gas chromatography wax dissolution analysis. The concentration of wax dissolved in dodecane was analyzed by gas chromatography (Agilent Technologies 7820A). The elution time for dodecane occurs at about 3.9 minutes while peaks for paraffin wax appear from 13 to 30 minutes due to the multi-component nature of paraffin wax used. The most intense peak for paraffin wax was observed at 17.3 minutes and was used as the reference. Wax concentration in dodecane for each sample was extrapolated from a calibration curve of peak intensity vs paraffin wax concentration for known amounts of paraffin wax dissolved in dodecane.
