“…The disadvantage in using organic solvents for isolation of epicuticular waxes is that the resultant extract also includes the intracuticular waxes [25]. However, this method is commonly used to study the properties of the cuticle in studies of the chemical composition and mechanisms of crystallization of the waxes [2,6,9,11,12]. In this study, the 3-minute chloroform treatment of the leaves was sufficient to extract the waxes of S. domestica and C. granatensis.…”

“…The application of direct isolation of the epicuticular waxes without using solvents, but after freezing and transferring on artificial carrier material, was efficient for their mixtures were used for wax extraction, the chloroform solvent was most generally used throughout numerous studies [2,6,8,9,11,12,23,24]. According to McWhorter et al [8], 30-seconds washing in chloroform removed essentially all the wax from the leaf surface.…”

“…The waxes from C. granatensis formed homogeneous layers on the plastic plates while the waxes extracted from S. domestica recrystallized inhomogeneously. Koch et al [2] investigating the growth process of nonacosan tubules also observed inhomogeneous circular growth pattern and named it "coffee-drop effect". The authors [2] suggested this was due to the evaporation of the solution and the most homogeneous part was the one which dries last.…”

Wax morphology and chemical composition are widely accepted to be important for the protective properties of the leaf’s surface and also valuable characteristics in plant systematics. The leaves of Sorbus domestica L. and Cotoneaster granatensis Boiss., species of two large genera with intricate taxonomy referred to subtribe Pyrinae, Rosaceae (formerly subfamily Maloideae), were studied by scanning electron microscope (SEM) and performing different methods of wax isolation. The aim of the study was to acquire a suitable, cost and time effective method for wax removal. Chloroform and methanol extractions and freeze-embedding method for direct isolation of the wax crystals were applied. Immersing the leaves for 3 minutes in chloroform was sufficient to extract the waxes whereas the efficiency of the methanol solvent was lower. Wax layers with wellpreserved structures of the crystals from both upper and lower epidermis were successfully transferred to artificial surfaces. The recrystallization experiment demonstrated that waxes from chloroform extracts could recrystallize in in vitro conditions on artificial surfaces. The crystals showed same micromorphology as on the intact leaves. Results of this study could be applied in further analytical researches of the waxes of S. domestica and C. granatensis or other species of the subtribe Pyrinae.

“…However, new developments show that other considerations for CA and CA hysteresis may need to be taken as well. Gao and McCarthy suggested that the contact line model is better approach to predict superhydrophobicity of surfaces McCarthy 2007, 2009 (Koch et al 2009a;Niemietz et al 2009;Cao 2010;Guo and Wang 2010;Bhushan and Jung 2011;Pechook and Pokroy 2012). The study of Wang et al (2013) showed combined effects of the spherical silica nanoparticles (roughness increment) and their hydrophobization with HDTMS as a promising approach for surface treatment of wood.…”

Plant surfaces provide an unlimited source of systems for the protection of their surface against the outer environment. These systems have continuously improved over the last 400 million years of evolution. Two of the most fascinating properties of these systems are superhydrophobicity and the self-cleaning ability of several plant species. These properties are most often achieved due to the hierarchical structure of the surface in combination with a deposited blend of epicuticular waxes. In this study, a layer of n-hexatriacontane was deposited on wood surfaces via thermal evaporation, and the self-assembly ability was investigated for various wood species with differently machined surfaces. The behavior of wax crystals was observed using scanning electron microscopy (SEM) and confocal microscopy. The impact on wettability was investigated by measuring contact angles and tilt angles. With wax deposition, a significant change of wettability was achieved, which was represented by the transition from hydrophilic to superhydrophobic surface behavior. The self-assembly ability of n-hexatriacontane resulted in an increased contact angle in all observed samples.
