Published Methods of Thin Film Formation Using Meliorum's Nanomaterials

Meliorum scientists and engineers have spoken with several different customers to obtain information on various techniques that are used to deposit our nanomaterials for the purpose of making nanoparticle thin films. We have selected four different academic articles from our list of customers, each describing a different method for making thin films.

The first article employs a laser heating method. A laser is used to “sinter” the particles, which leverages a unique property of nanoparticles to generally have a lower melting temperature than its associated solid. The details of the process – which specifically uses our silicon nanoparticles – are described in the article [1].

The second article discusses an ink jet sintering method. This is the method that is used most often currently, and various industrial style ink jet printers can be used to deposit and heat on a given substrate, for sintering of the particles to take place. Once again, our silicon nanoparticles are featured in the article [2].

The third article discusses the use of a Langmuir Blodgett method for deposition of our silicon nanoparticles on a given substrate. These particular particles, again manufactured by us, have been previously stabilized by us using sodium dodecylbenzenesulfonate for this work, however, a brief horn or probe ultrasonication would also work to ensure the distribution of particles is even and homogeneous [3].

Lastly, the fourth article discusses the use of our particles in a PVDF (poly(vinylidene fluoride), molecular weight=534,000) matrix, dispersed in 1-methyl-2-pyrrolidone. Described in detail in the “Experimental Section,” the particles are mixed with the PVDF, and the PVDF is used as a matrix for drop-casting with a subsequent 90°C oven cure [4].

Meliorum is proud to be in a position to support such critical applied research. As many products see improvements in their feature offerings and performance as a result of their incorporation with nanomaterials, it becomes ever more critical to fully characterize the manner and process in which these materials can be modified into different form factors.

The article abstracts may be accessed by clicking the respective footnote references above. The same silicon nanomaterials that were used in the experimentation are featured in Meliorum's silicon nanoparticles page.

Please note that any or all of the mentioned thin film formation techniques may be patent protected. Please contact the authors of the relevant research for additional information.
