Using plasma treatment and spin coating in combination, researchers can achieve uniform material coatings with improved stability and performance.
Plasma treatment alters surface chemistry by introducing hydrophilic oxygen containing functional groups. Polar groups make the substrate wettable and better able to interact with aqueous solutions. As a result, plasma treatment promotes adhesion and smooth spreading over the substrate.
Spin coating devices employ centrifugal force to create level, even films and coatings. Through experimentation with rotation speed and acceleration, researchers can target specific film thickness with precision. Spin coating improves device quality and professional appearances.
Together, these tools work seamlessly to provide uniform films and coatings across a variety of substrates. In numerous applications, consistent coating characteristics promote stability and functionaltity.
Plasma cleaning and spin coating improve the conductivity and work function of PEDOT:PSS dispersions. Flexible electronics and solar cells are light weight, low cost, and high performance.
Plasma and spin coating facilitate a smooth deposition of photoresist onto substrate surfaces. Precision is key in the development of micro or nanoscale features.
Plasma treatment and spin coating are often used to disperse nanoparticles or microbeads suspended in aqueous solution. Plasma treatment can be used to tune nanoparticle surface chemisty, size and shape.
Thin Polymer Films
Thin polymer films have versatile physical properties: insulating, high capacitance, durable, stretchable. They play a vital role in numerous applications. Spin coated polymers include PEI, PMMA, PCL, PEMA, PDMS, PEDOT:PSS, PSS, Nylon, PU and many more.
Smooth PDMS membranes not only enhance microfluidic device quality and aesthetics, but improve device performance. PDMS membrane can be designed to exchange gas or small molecules without direct contact.
Surface chemisty and physical properties are essential to the biological microenvironment. Biological coatings can improve cell viability or prevent biofilm formation. Spin coated materials include DETA, gelatin, agarose, silanes, polymers and more.
