How 3D Printing Creates Self-Assembling Superconductors

Cornell researchers unveiled a novel superconductor fabrication method that relies on special 3D printable ink and self-assembly to create specific nanostructures. This strategy enables engineers to create superconductors with specific traits and properties with less effort and requiring less specialized machinery. It has the potential to revolutionize computing, quantum sciences, and much more. Here’s what you need to know.

Self-Assembly (SA) Nanostructures

Self-assembly (SA) refers to a natural phenomenon where atoms, molecules, or particles automatically organize into specific shapes without any intervention. This strategy offers a reliable and effective method for engineers to create durable microscopic structures without requiring specialized machinery to complete the task.

Self-assembly works due to noncovalent forces acting in relation to environmental factors. The tiny nanostructure building blocks will automatically form into structures that provide optimal energy usage. These tiny shapes offer high scalability, durability, and other ideal traits for tasks such as creating superconductors.

Notably, SA projects have become more popular with the first self-assembled superconductor revealed in 2016. Interestingly, many of the same engineers worked on this latest project, highlighting the long-term nature and importance of their contributions to the nanostructural sciences.

Problems with SA Approaches

There are some technical roadblocks to SA strategies that engineers must overcome if they intend to take this fabrication method to its fullest potential. For one, different nanostructures require different ordering kinetics of separate processes at different length scales.

Additionally, engineers have found that 3D printing functional crystalline porous inorganic nanomaterials remains a difficult challenge. The current strategy relies on a multifaceted approach that includes synthesizing porous materials separately.

The materials are first converted into a powder form so that they can be mixed with binders. From there, the mixture gets reprocessed before heading toward the final stage, heat treatment. The procedure is time-consuming, expensive, and limited in what nanostructures and materials can be used.

Block Copolymer (BCP) SA-derived Mesostructures

Engineers have put a lot of work into developing the strongest and most effective nanostructures. The use of Block copolymer (BCP) SA-derived mesostructures has opened the door for more applications recently. These tiny designs provide enhanced structural rigidity and control. Specifically, BCP nanostructures enable engineers to alter mesoscale lattices and lattice parameters to create stronger, high-performance options.

Notably, BCP SA-based hierarchically ordered mesoporous transition metal compounds are seen as the future of this technology. However, to date, there’s never been a study demonstrating how to successfully 3D print BCP nanostructures effectively.

Mapping

One of the first steps the engineers took was to create a computer map of the nanostructures and their formation processes. This strategy enabled them to determine key details like which polymer molar mass offers the highest superconductor performance and more.

Direct Ink Writing Process

The engineers came up with a unique strategy that relied on a “one-pot” approach to printing. This strategy utilized a special ink created using Pluronics-family block copolymers (BCPs). Interestingly, the BCPs get combined with transition metal sols that were hydrolyzed from metal alkoxides in acidic ethanol solutions. This strategy provides better efficiency and lower costs versus traditional methods that rely on the powdering process.

Printing

A special 3D printer nozzle was created to support the one-pot ink strategy. The device utilized a syringe pump-type print head to deliver the material. Specifically, the purpose-built printer head extrudes the ink into a dish containing other materials based on what type of nanostructure the scientists want to create.

Specifically, hexane-filled dishes were used to create periodic cubic woodpile structures. Also, a gel-like fluid that contained 25% Pluronic F127 by mass in water was used as another alternative. This substance could self-assemble into periodic helical structures.

Thermal Processing

The final stage of the fabrication process involves thermal processing. When heat is applied to the print, it causes a reaction leading to the formation of hierarchically ordered and porous crystalline oxides and nitrides. These materials then self-assemble into periodic mesostructures ideal for use as crystalline superconductors

Structure Control

The engineers noted that the scalable porous functional inorganic material formations provided them with the ability to single out specific properties. They documented three specific length scales, including combined atomic lattices, SA-based mesoscale lattices, and 3D printing-induced macroscopic lattices.

This approach skips many of the time-consuming and costly steps of previous methods and enables engineers to determine structural attributes via oxide or nitride crystallization. Specifically, the team utilized block copolymer self-assembly to create mesostructured lattices, which can include coils or helices, making them ideal for various use case scenarios.

Drying and Setting

Following the treatment, the nanostructures are exposed to open air before undergoing another round of heat exposure in ammonia and carburizing gas. This step utilizes higher temperatures of 950 °C to convert oxides into specific crystalline transition metal nitride helices and hexagonally ordered woodpiles containing atomic lattices.

Self-Assembling 3D Printed Superconductor Test

To test their “one-pot” ink formulation and printing techniques, the team created several test scenarios, aiming to monitor the effects of the process on durability and assembly times. The first step was to create free-standing, hybrid woodpile lattices.

The woodpile lattices contained mesoporous helical structures of oxides and nitrides. This key detail is very important due to the fact that, in the past, it was nearly impossible to print a non-self-supporting configuration directly. To accomplish the task, engineers relied on their mapping algorithm to determine optimal macromolecular characteristics and design.

Self-Assembling 3D Printed Superconductor Test Results

The printing test yielded some impressive results. For one, they found that the approach can print complex shapes with higher performance than any previous methods. They noted that much of this durability can be attributed to the retention of mesostructure found in the final crystalline materials, which contain periodic lattices.

Impressively, the new superconductor material outperformed predecessors with an upper critical magnetic field of 40 to 50 Tesla. Notably, this is a new record, dwarfing previous attempts. The scientist also noted that the printed lattices are superconducting, with their levels of conductivity determined by molar mass and surface area.
