“…The values are also consistent with those reported for plasma thin films deposited from other secondary plant metabolites, where total SFTs of 45-48, 36-40 and 31-37 mJ·m −2 were found for thin films derived from linalyl acetate [68], Lavandula angustifolia essential oil [7] and terpinen-4-ol [69], respectively.…”

“…Another important illustration of the wetting behaviour of liquids on the pp-GT thin film surface can be performed from their wetting envelopes. These are the lines of constant equilibrium CA on a plot of the polar fraction (γ L AB ) versus the dispersive fraction (γ L LW ) of the liquid determined from the following equation [68]: Figure 8 demonstrates the degree to which various liquids wet the pp-GT film surfaces fabricated at different RF power if γ L AB and γ L LW are known. It also illustrates the surface properties of ideal liquids for solution processing on the pp-GT thin films.…”

Investigations on the wetting, solubility and chemical composition of plasma polymer thin films provide an insight into the feasibility of implementing these polymeric materials in organic electronics, particularly where wet solution processing is involved. In this study, thin films were prepared from 1-isopropyl-4-methyl-1,4-cyclohexadiene (γ-Terpinene) using radio frequency (RF) plasma polymerization. FTIR showed the polymers to be structurally dissimilar to the original monomer and highly cross-linked, where the loss of original functional groups and the degree of cross-linking increased with deposition power. The polymer surfaces were hydrocarbon-rich, with oxygen present in the form of O-H and C=O functional groups. The oxygen content decreased with deposition power, with films becoming more hydrophobic and, thus, less wettable. The advancing and receding contact angles were investigated, and the water advancing contact angle was found to increase from 63.14° to 73.53° for thin films prepared with an RF power of 10 W to 75 W. The wetting envelopes for the surfaces were constructed to enable the prediction of the surfaces' wettability for other solvents. The effect of roughness on the wetting behaviour of the films was insignificant. The polymers were determined to resist solubilization in solvents commonly used in the deposition of organic semiconducting layers, including chloroform and chlorobenzene, with higher stability observed in films fabricated at higher RF power.

“…When a liquid completely wets a surface (cos Θ = 1), the following equation is obtained [ 20 , 26 , 27 ]: σ l d + σ l p = ( σ l d σ s d ) 1/2 + ( σ l p σ s p ) 1/2 . …”

“…Resolved to R , as a function of φ , the equation shows the value in the coordination system for complete wetting. When considering this function for φ in the range of 0–90°, R ( φ ) can be calculated to provide the wetting envelope for a certain surface energy as follows [ 20 , 26 , 27 ]: R ( φ ) = {[(cos φ σ s d ) 1/2 + (sin φ σ s p ) 1/2 ]/(cos φ + sin φ )} 2 . …”

Root canal sealers should have good wetting and adhesion with intraradicular dentin. This study evaluated the wetting and adhesion properties of three bioceramic root canal sealers on dentin using contact angle (CA) measurements and calculations based on the Owens–Wendt–Rabel–Kälble (OWRK) model and compared the properties with those of a resin sealer. Three bioceramic sealers (EndoSequence BC Sealer (BC); Endoseal MTA (EM); and MTA Fillapex (MF)) were tested, together with one epoxy resin-based sealer (AH Plus (AP)). Disc-shaped sealer specimens and human premolar teeth with flat and polished intraradicular dentin surfaces were prepared (n = 12). The CAs of two liquids (water and methylene iodide) were measured on the surfaces using the sessile drop method. The wetting and adhesion properties of the four sealers were calculated using the wetting envelope and isogram diagram, respectively. Group BC showed the best wettability among the four sealer groups. The best adhesion was achieved for group EM, followed by group BC, with a significant difference being present between the two groups (p < 0.05). The OWRK-based calculation indicated that the bioceramic BC and EM sealers showed superior wetting and adhesion properties to the AP sealers.

Understanding the polymerization mechanism of a precursor is indispensable to enhance the requisite material properties. In situ mass spectroscopy and X‐ray photoelectron spectroscopy is used in this study to understand the RF plasma polymerization of γ‐terpinene. High‐resolution mass spectra positive ion mass spectrometry data of the plasma phase demonstrates the presence of oligomeric species of the type [M+H]+ and [2M+H]+, where M represents a unit of the starting material. In addition, there is abundant fragmented species, with most dominant being [M+] (136 m/z), C10H13+ (133 m/z), C9H11+ (119 m/z), and C7H9+ (93 m/z). The results reported in this manuscript enables to comprehend the relationship between the degree of incorporation of oxygen and the rate of deposition with the input RF power.
