This study aims to evaluate the adsorptive, adhesive, and wetting energetic properties of five commercially available cleansers in contact with model dental polymer (PMMA). It was assumed that the selected parameters allow for determining the optimal concentration and place of key component accumulation for antibacterial activity in the bulk liquid phase and prevention of oral plaque formation at the prosthetic material surface. The adsorptive (Gibbs' excesses , critical micellar concentration) and thermal (entropy and enthalpy) surface characteristics originated from surface tension and dependences. The surface wetting properties were quantified upon the contact angle hysteresis formalism on the advancing , receding contact angles, and as the input data, which yield a set of wettability parameters: 2D adsorptive film pressure, surface free energy with its dispersive and polar components, work of adhesion, and adhesional tension, considered as interfacial interaction indicators. In particular, molecular partitioning and are indicators of the efficiency of particular active substance accumulation in the volume phase, while , /, and point to the degree of its accumulation at the immersed polymer surface. Finally, the liquid penetration coefficient and the Marangoni temperature gradient-driven liquid flow speed were estimated.
本研究旨在评估五种市售清洁剂与模型牙科聚合物（聚甲基丙烯酸甲酯）接触时的吸附、粘附和湿润能量特性。假设所选参数能够确定关键成分在本体液相中抗菌活性的最佳浓度和积累位置，并防止在修复材料表面形成牙菌斑。吸附（吉布斯过量、临界胶束浓度）和热（熵和焓）表面特性源自表面张力和相关依赖性。表面湿润特性根据前进接触角、后退接触角的接触角滞后形式进行量化，并作为输入数据，由此得出一组湿润性参数：二维吸附膜压力、具有分散和极性成分的表面自由能、粘附功和粘附张力，这些被视为界面相互作用指标。特别地，分子分配系数和是特定活性物质在体积相中积累效率的指标，而、/和则表明其在浸入聚合物表面的积累程度。最后，估算了液体渗透系数和马兰戈尼温度梯度驱动的液体流速。
