AB  - Three types of thermoplastic polymers, acrylonitrile butadiene styrene (ABS), 
      polymethyl methacrylate acrylic (PMMA) and high-density polyethylene (HDPE), were 
      enriched with silver nanoparticles (AgNPs) of 0.5 wt.% and 1.0 wt.%, 
      respectively. The polymers and the composites were manufactured via injection 
      molding. Regarding the potential of these polymers as matrices for long-term use 
      as biomaterials, the aim of this study was to examine their stability in the in 
      vitro conditions during a three-year incubation period in deionized water. In 
      this work, microstructural observations were performed, and mechanical properties 
      were assessed. Surface parameters, such as roughness and contact angle, were 
      comprehensively investigated. The microstructural evaluation showed that the 
      silver additive was homogeneously dispersed in all the examined matrices. The 
      36-month immersion period indicated no microstructural changes and proved the 
      composites' stability. The mechanical tests confirmed that the composites 
      retained comparable mechanical properties after the silver incorporation. The 
      Young's modulus and tensile strength increased during long-term incubation. The 
      addition of silver nanoparticles did not alter the composites' roughness. The 
      contact angle increased with the rising AgNP content. It was also shown that the 
      materials' roughness increased with the incubation time, especially for the ABS- 
      and HDPE-based materials. The water environment conditions improved the 
      wettability of the tested materials. However, the silver nanoparticles' content 
      resulted in the contact angle decreasing during incubation. The conducted studies 
      confirmed that the mechanical properties of all the polymers and composites did 
      not deteriorate; thus, the materials may be considered stable and applicable for 
      long-term working periods in aqueous environments.
