Case Study

Polyamide Used for the Preparation of MOF-Derived Photothermal Antibacterial Films

Zhang, Yu, et al. Colloids and Surfaces A: Physicochemical and Engineering Aspects (2025): 136642.

In this study, polyamide (PA) was utilized as the polymer matrix for the fabrication of photothermal antibacterial composite films (PA@C@Ag), incorporating MOF-derived carbon nanoparticles (CNPs) and silver nanoparticles (AgNPs). The experimental procedure focused on stepwise film construction and functionalization to achieve both thermal and antibacterial performance.
First, varying amounts of CNPs (ranging from 10 mg to 2000 mg) were dispersed in a formic acid solution of PA and subjected to ultrasonic treatment for 20 minutes to ensure uniform nanoparticle distribution. Then, 100 μL of the homogeneous suspension was cast onto glass substrates to form 1 × 1 cm² films, which were oven-dried at 60 °C to yield PA@C films.
For silver functionalization, citrate-stabilized AgNPs solutions (adjusted to pH 6.0 using 0.1 M HCl or NaOH) were prepared. The PA@C films were immersed in the AgNPs solution for 4, 8, 12, or 24 hours, enabling the adhesion of AgNPs via hydrogen bonding between the citrate's carboxylate groups and the amide groups in PA.
This systematic fabrication strategy resulted in flexible films with high light absorption and wide-range photothermal responsiveness, laying the groundwork for effective visible/infrared light-driven antibacterial applications.

Polyamide Used for the Preparation of Flexible n-Type Thermoelectric SWCNT Composite Films

Xiao, Jiye, et al. Journal of Materials Science & Technology 207 (2025): 246-254.

In this study, polyamide-6 (PA6) and polyamide-66 (PA66), traditionally employed in fiber manufacturing, were applied as novel dopants for converting p-type single-walled carbon nanotubes (SWCNTs) into flexible n-type thermoelectric materials. The experimental workflow emphasized controlled dispersion, doping, and film fabrication for optimizing thermoelectric performance.
To begin, 30 mg of SWCNTs were dispersed in 20 mL of N-methyl-2-pyrrolidone (NMP) via magnetic stirring for 24 h and sonication for 1 h to achieve homogeneous suspension. In parallel, PA6 or PA66 was dissolved in 10 mL of NMP at 165 °C under stirring, using various weight ratios relative to SWCNTs (7:3, 5:5, 3:7, and 1:9). Once fully dissolved, the polyamide solution was combined with the SWCNT suspension and further stirred vigorously for 30 min to ensure uniform mixing and doping.
The resultant composite solution was cast into a PTFE mold and dried in air at 50 °C for 5 h. Subsequent vacuum drying at 80 °C for 48 h yielded flexible, free-standing films. For comparison, p-type SWCNT films were prepared using DMSO as the dispersion medium under similar conditions.
The amide-functionalized polyamides facilitated electron transfer, resulting in notable negative thermopower values of -56.0 μV K⁻¹ (PA66) and -54.5 μV K⁻¹ (PA6), marking significant progress in n-type organic thermoelectric material development.

Polyamide-12 Used for the Preparation of Electrically Conductive Composites for SLS 3D Printing Applications

Kseniya, Shiyanova, et al. Composites Part A: Applied Science and Manufacturing 193 (2025): 108829.

Polyamide-12 (PA12), a widely utilized thermoplastic polymer, has been effectively modified to create electrically conductive composites for advanced additive manufacturing. In this study, PA12 powder was surface-functionalized with single-walled carbon nanotubes (SWCNTs) to enable its application in selective laser sintering (SLS), a key technique in industrial 3D printing.
The composite preparation involved dispersing varying concentrations of SWCNTs (0.01-2 wt% relative to PA) in isopropyl alcohol, followed by sonication under controlled cooling to achieve homogeneous dispersion. During the final stage of sonication, PA12 powder was introduced into the suspension to ensure even coating of the polymer surface. The mixture was then filtered, and residual solvent was removed by air-drying at 80 °C for 24 hours.
The incorporation of SWCNTs conferred electrical conductivity to the PA12 matrix without compromising its processability, making it suitable for SLS. This method highlights an efficient and scalable approach to modifying PA12, transforming it into a functional material for applications requiring electrostatic dissipation, sensing, or structural health monitoring.
This work demonstrates the versatility of Polyamide-12 as a host polymer for nanofiller integration and its expanding potential in the production of functional components through additive manufacturing technologies.
