Abstract

Advancing and receding contact angles of several aqueous surfactant and polymer solutions were measured on paraffin wax (PF), poly(methyl methacrylate) (PMMA), poly(ethylene terephthalate) (PET), and polyethylene (PE). The polymers used included hydroxypropylcellulose (HPC), hydroxypropylmethylcellulose (HPMC), poly(vinyl pyrrolidone) (PVP), poly(ethylene glycol) (PEG) and hydroxyethylcellulose (HEC). Plots of adhesion tension, γLVcosθ, versus surface tension, γLV, were used to analyze factors influencing the ability of the polymers to affect advancing contact angles, relative to surfactants. Whereas all polymers and surfactants exhibited predictable and nonspecific effects on PF, the more hydrophobic polymers HPC and HPMC and all surfactants on PMMA, PET, and PE were less efficient in reducing the contact angle than a pure liquid with the same surface tension. These observations were interpreted in terms of the relative adsorption of solute at the solid—liquid and liquid—vapor interfaces. Receding contact angle measurements revealed no specific effects on PF for any solute, nor did the more hydrophilic polymers show specific effects on any solid. However, the hydrophobic polymers, HPC and HPMC, at all concentrations, and all surfactants above a certain concentration, caused zero degree receding angles to occur on all solids except PF, even when advancing angles were quite high. These effects are attributed to the specific nature of polymer and surfactant adsorption at the solid surface.

    The use of polymethyl methacrylate (PMMA) as a biopolymer for the preparation of particles through microencapsulation methodologies has been used for controlled release systems for oral administration and in multifactorial actions such as in the treatment of diseases (cancer, duschene dystrophy, parasites), dental prostheses and others [16,22–29]. PMMA is a non-biodegradable synthetic homopolymer with hydrophobic characteristics, but its contact with aqueous solutions makes it slightly hydrophilic [30,31]. PMMA polymer particles are an important tool in biomedical engineering because of their biocompatibility and stabilizing property of the formulation [27,31].

    For the reader’s ease of comprehension, a more detailed tabulation is provided in Table S1 of the Supplementary Material. Johnson et al. [18] found that the θa of an aqueous surfactant/polymer solution drop is largely dependent on the extent up to which the molecules adsorb onto the solid–liquid interface. The results in Drelich et al. [20] reported that an increase in surface roughness and chemical heterogeneity of a solid substrate caused greater discrepancies between the θa values measured using sessile-drop and captive bubble techniques.

    Values of the contact angle, β, used in the calculations were either taken from the literature or estimated by least squares regression, fitting the model to the experimental data with β constrained to lie within bounds set by literature values. For NaOH solutions on stainless steel, β=35° (Aspentech, 2008); for water on stainless steel, β=35° (Boulangé-Petermann et al., 2008 reported a range of 30–37°); for water on acrylic (polymethyl methacrylate), β=53° (Johnson et al., 1986 reported a range of 52–76°). Data were not available for the detergent solution on acrylic, and a β value of 75° was found to give the best fit for the model to the experimental data.
