In materials science and chemical engineering, the preparation of uniform and reliable thin film samples is a critical step in obtaining valid data. Although traditional methods such as scraping and spinning coating are widely used, they often have limitations in the face of special trait substrates and high-throughput batch screening needs. The Huino reciprocating spray Film Applicator is a specialized tool designed to meet these specific challenges.
Recommended solution: Make up for the blind spot of traditional coating technology
1. Non-contact uniform coating for special substrates
The inherent physical contact and shear forces of traditional scraping techniques pose challenges to many special substrates: porous or brittle substrates (e.g., battery separators) can lead to deformation, breakage, or excessive slurry penetration; For flexible or uneven surfaces (e.g., flexible electrodes), it is difficult to achieve uniform coating; For substrates with prefabricated microstructures on the surface, there is a risk of scratching or contaminating the delicate structure.
Solution 1 of automatic spraying film coating machine:
The automatic spraying coating machine offers a systematic solution for this: its core technology is the use of non-contact pneumatic atomization spraying, which in principle eliminates physical contact damage to fragile, porous or complex structural substrates. On this basis, the vacuum adsorption platform can firmly fix flexible or thin and light substrates, providing a flat and stable foundation for the coating process and ensuring uniform coating. Finally, by precisely adjusting key parameters such as spraying speed, discharge volume, and number of reciprocations, the slurry deposition process is accurately and controllable, so as to obtain uniform and consistent qualified coatings on various characteristic surfaces.
Examples of applicable scenarios:
In solid-state battery development, inorganic-polymer composite electrolyte layers are prepared on a flexible polymer separator.
In the development of functional fabrics, the surface of the textile is coated with a conductive or sensing material.
In the field of microelectronics, substrates with existing circuit patterns are selectively coated with protective layers.
2. Batch consistent sample preparation that serves R&D efficiency
In the critical stage of material research and development, scientific research work faces severe challenges: firstly, when formulating formulations, it is necessary to ensure that the film thickness of multiple replicates under the same formula is highly consistent, otherwise the difference in film thickness will seriously interfere with the fair evaluation of the intrinsic properties of the material. Secondly, when optimizing the post-process parameters such as sintering temperature and annealing time, all samples to be tested must have exactly the same initial film thickness, otherwise the experimental conclusion will be unconvincing due to the existence of variables. More fundamentally, the human error that is difficult to overcome by manual coating leads to the inability to reproduce samples prepared in different batches, which directly shakes the reliability of scientific research data and poses an obstacle to the publication of research results.
Solution 2 of automatic spraying coating machine:
The equipment is programmable and automated, and all key process parameters can be digitally preset and stored through the touch screen, ensuring that each operation strictly follows the set procedure, fundamentally eliminating the uncertainty of manual operation. This precise control results in reliable repeatability, and once the parameters are determined, the equipment can prepare sample sets with minimal film thickness differences on multiple substrates with extreme accuracy, providing a fair and reliable basis for formulation screening and process optimization studies.
Examples of applicable scenarios:
In the field of cutting-edge material research and development, such as the development of new photovoltaic materials or lithium battery cathode materials, this equipment can quickly prepare thin film sample arrays containing dozens of different components and ensure that multiple samples within each formulation have a highly consistent film thickness, thus providing a reliable basis for high-throughput performance screening. In the scientific research and teaching scenario of colleges and universities, it can provide standardized film-making conditions for students' experiments, ensure that the starting point of the samples obtained by each student is consistent, which greatly facilitates the horizontal comparison and data analysis of experimental results, and effectively improves the rigor of teaching and scientific research training.
