We report on the investigation of stearic acid-layered double hydroxide (LDH) composite films, with controlled wettability capabilities, deposited by a combined pulsed laser deposition (PLD)-matrix-assisted pulsed laser evaporation (MAPLE) system. Two pulsed lasers working in IR or UV were used for experiments, allowing the use of proper deposition parameters (wavelength, laser fluence, repetition rate) for each organic and inorganic component material. We have studied the time stability and wettability properties of the films and we have seen that the morphology of the surface has a low effect on the wettability of the surfaces. The obtained composite films consist in stearic acid aggregates in LDH structure, exhibiting a shift to hydrophobicity after 36 months of storage.

The effect of the drying temperature on the secondary structure of the soybean protein-isolate/carboxymethyl cellulose/stearic acid composite films was evaluated. The Fourier transform-infrared spectra showed that the stearic acid lose some characteristic absorptions. Hence, the stearic acid was well integrated with the other ingredients. The absorption band (1600~1700 cm-1) of the composite film was deconvoluted into 9 peaks for the calculation of their secondary structure. The β-sheet content of the composite films dried at 90 oC was significant higher than that of the control. Hence, the composite films dried at 90 oC was more stable than the control.

The thermalgravimetric and differential scanning calorimetry analysis were used to evaluated the state of stearic acid in the soybean protein-isolate/carboxymethyl cellulose composite films. The stearic acid lose its weight rapidly in 210~280 oC, while no significant weight loss presented among 210~280 oC in the profiles of the control and the composite films dried at 90 oC. Hence, the stearic acid was well interacted with the other ingredients. Moreover, the stearic acid was distributed as the free state and bound state in the composite films. The free stearic acid ratio of the composite films dried at 90 oC was the lowest among the tested films. The temperature of 90 oC effectively enhanced the interaction of the SA with the other ingredients.

A surface coating formed by stearic acid (SA) crystals was prepared by repeatedly dipping a silicon substrate into a SA solution and drying it in air. Scanning electron microscopy imaging revealed that the surface roughness of the coating increases with each dip-and-dry cycle. The coating appears as a carpet of hydrophobic ‘blades’, and is superhydrophobic (after 20 dipping cycles advancing contact angle ~160°), even after immersion in water for up to 2 h. This simple method could be applied to large areas, making this an interesting alternative to high-tech surface modification techniques.
