We present a procedure for highly controlled and wrinkle-free transfer of block copolymer thin films onto porous support substrates using a 3D-printed drain chamber. The drain chamber design is of general relevance to all procedures involving transfer of macromolecular films onto porous substrates, which is normally done by hand in an irreproducible fashion.

Sparks, Department of Materials Science and Engineering, The University of Utah, Salt Lake City, UT Electroplating is a process that uses electric current to reduce dissolved metal cations so that they form a thin coating on an electrode. Other thin film deposition techniques include chemical vapor deposition (CVD), spin coating, dip coating, and sputter deposition among others. CVD uses a gas-phase precursor of the element to be...

We describe a method for the fabrication of large-area (up to 13 cm diameter) and ultrathin (as thin as 8 nm) polymer films. Instead of using a sacrificial interlayer to delaminate the film from its substrate, we use a self-limiting surface treatment suitable for arbitrarily large areas.

The two-thermal annealing method enables the fabrication of thin films of type II semiconductor silicon clathrate. Post-synthesis treatments, including thermal pressing and reactive ion etching, were performed to improve the material properties. This approach provides an accessible pathway for fabricating tunable clathrate films suitable for next-generation electronic and photonic devices.

FAQs
Interfacial adhesion determines whether the film remains attached to the donor substrate or separates during release. The process adjusts this interface so the layer can be detached without losing its structure or function, then bonded to the receiving substrate. This balance is central to transferring delicate films while avoiding processing conditions that could damage the material.
Thin film transfer can reduce donor-substrate adhesion through several mechanisms. Sacrificial-layer release removes an intermediate layer, mechanical delamination separates the film by applied force, and thermal or chemical treatment changes the interface to promote separation. These approaches provide different ways to free the film before bonding it to a target surface.
Substrate compatibility matters because the donor and receiving surfaces may impose different processing constraints. Transfer allows a thin layer to be fabricated or supported on one substrate and then integrated with another that offers more suitable mechanical, electrical, or device-related conditions. Preserving the film's structure and function during this transition determines the usefulness of the process.
A typical sequence begins with a thin layer on a temporary donor substrate, followed by controlled reduction of adhesion at the film-substrate interface. The released layer is then positioned on the receiving substrate and bonded to it. The process must maintain the film's structural integrity and function throughout release, handling, and integration.
The approach supports transfer of semiconductors, metals, polymers, and functional coatings. It is valuable when the desired film and target substrate cannot be processed together under the same conditions. Separating fabrication from final integration expands the combinations of materials and surfaces available for engineered multilayer structures and advanced devices.
Thin film transfer supports flexible electronics, microelectromechanical systems, optoelectronics, and advanced devices. In these areas, it helps combine functional layers with substrates that are difficult to process directly, while reducing material or processing constraints. The technique also enables multilayer architectures, allowing device designs to incorporate transferred films in organized combinations.
