The article presents the results of research on the impact of the use of an original, innovative method of deposition of Parylene C on the functional properties of fabrics with various potential applications (e.g., thermal and chemical protective clothing, packaging, covers and others). Verification of the effects of the method used was based on interdisciplinary research taking into account the impact of coating fabrics on changes in their structure (micro-CT), surface properties (contact angle), barrier properties (water and chemical liquid wetting), electrostatic properties (charge decay), biophysical properties describing heat and mass transfer (by the Alambeta system and thermal imaging) and flammable properties. Four fabrics made of synthetic organic fibres (meta-aramid, para-aramid) and natural inorganic fibres (basalt) were selected for testing. Given the complex structure of textile substrates, the results confirmed that the two assumed thicknesses of the Parylene C coating were consistent with the actual measurements. The findings indicated that the coatings significantly reduced water and acid absorption in the fabrics compared to unmodified ones. Thermal insulation property tests revealed that coated fabrics exhibited higher thermal conductivity than unmodified fabrics. Additionally, the presence of Parylene C on aramid fabrics resulted in a modest increase in their ignition resistance.
本文介绍了采用原创、创新的聚对二甲苯C沉积方法对具有各种潜在应用(如热防护和化学防护服、包装、覆盖物等)的织物功能特性影响的研究结果。所采用方法效果的验证基于跨学科研究,考虑了涂覆织物对其结构变化(微观CT)、表面特性(接触角)、阻隔特性(水和化学液体润湿)、静电特性(电荷衰减)、描述热质传递的生物物理特性(通过Alambeta系统和热成像)以及易燃特性的影响。选择了四种由合成有机纤维(间位芳纶、对位芳纶)和天然无机纤维(玄武岩)制成的织物进行测试。鉴于纺织基材的复杂结构,结果证实聚对二甲苯C涂层的两种假定厚度与实际测量值一致。研究结果表明,与未改性织物相比,涂层显著降低了织物对水和酸的吸收。隔热性能测试表明,涂覆织物的热导率高于未改性织物。此外,芳纶织物上聚对二甲苯C的存在使其耐燃性略有提高。
