Functional coatings for cutters

Computational nanotechnology for functional coatings

The computer simulations are powerful tools to understand and determine properties and behaviour for a broad range of materials and diverse applications, going to different time and length scales. In the applied computational chemistry group at IFAM the computer simulations have been successfully applied to support the experiments and develop coatings with improved functionalities. The computat...

Functional polysaccharides as edible coatings for cheese.

The objective of the present study was to apply the polysaccharides from different nontraditional sources for cheese coatings. Chitosan, galactomannan from Gleditsia triacanthos, and agar from Glacilaria birdiae were tested, with different formulations and with the addition of plasticizer and corn oil. The surface properties of the cheese and the wetting capacity of the coatings on the cheese w...

Colorless polydopamine coatings for creating functional interfaces

Since the emergence of surface modification techniques, including polydopamine (PDA) layers using a single deposition process that is based on the oxidative self-polymerization of dopamine (DA), the number of studies concerning the functionalization of material surfaces via PDA coating has increased. While PDA is simple to apply to cover onto various kinds of substrates, most of conventional PD...

Functional isoeugenol-modified nanogel coatings for implants

With the rapid development of new medical devices including dental implants, bacterial biofilm infections become more and more frequent. We developed a methodology to design bioactive coatings for medical devices based on functional aqueous nanogels. Nanogels with a controlled amount of surface-grafted anti-bacterial molecules (isoeugenol) were synthesized. The crucial step for the nanogel synt...
