A
s the medical technology advances, the requirements of the next-generation healthcare devices are urgently demanded.
Implantable and wearable medical devices are the latest applications over the decades. Nickel, copper and aluminum are
widely used in the aforementioned devices because of the simple process and low cost, however, adverse reactions such as
allergies and Alzheimer’s disease might take place due to the releasing of metal ion. A biocompatible material thus becomes
the most urgent demand. Platinum is considered to be the most promising material owing to its irreplaceable biocompatibility.
Moreover, silk is a common material used in clothes. The combination of Pt and silk is considered to be a promising candidate
for the medical devices. Electroless plating can put these composite materials into practice and further achieve homogeneous
metallized-surface due to the low deposition rate. Typical electroless plating consists of pretreatment to clean and roughen the
surface, catalyzation to embed the catalysts as a nucleation site into the substrate, and the plating step for the metallization.
In spite of the dominance of Pt, electroless plating of Pt remains less studied due to the hardship of controlling the deposition
of platinum by electroless technique via the traditional catalyzation. An up-to-date technique of supercritical carbon dioxide
(sc-CO
2
) assisted catalyzation is practiced in this study to overcome the instinct difficulty of Pt plating. With the help of the
exceptional self-diffusivity, low surface tension, and affinity to non-polar materials of sc-CO
2
, the catalyst can be inlaid to the
substrate while the substrate structure remains undamaged.
