Micro-/nano-encapsulation, specializing in process optimization & scale-up and controlled release
We offer a case-by-case optimization of micro- and nano-encapsulation processes of active materials of different nature (dyes, oils, reactants, organic solvents, fragrances, nanoparticles, etc.) in both polymeric/hybrid matrices (spheres) and core-shell structures. The optimization study, carried out in volumes between 2 and 10 L, consists of tuning the key experimental parameters aimed to finely control the particles properties, such as size (in the micro and nanoscale), size distribution, porosity, chemical and mechanical resistance, release mechanism (pH, temperature, light, pressure, etc.) and surface potential. Particular attention is given to the achievement of optimized synthetic processes that are reproducible, easily adaptable to the encapsulation of actives of similar properties and scalable. Both the encapsulation method (polymerization, precipitation, etc.) and the particle materials are selected depending on the stability of the actives and the required properties of the particles.
Technological applications of thermochromic & photochromic materials:
Within this context, we help companies to obtain products with enhanced thermochromic and photochromic properties. In particular, we work on the achievement of materials with fast-responsive photochromic properties (WO 2013/132123 A1) or with inverse photochromic behaviour. We also offer solutions to obtain photochromes with high fatigue resistance and reversible and irreversible thermochromic materials with high switching temperature (>100 oC).
Surface functionalization and design of hydrophobic and oleophobic materials:
The functionalization of surfaces with hydrophobic and olephobic properties can drastically improve the performance of many materials, such clothing and sport equipment that keep its owner dry and clean at any condition and self-cleaning surfaces. Our expertise on this field is to provide easy to apply coatings based on adhesive catechols derivatives to different kinds of textile fabrics. In addition, the main advantage of our technology in front other approaches is that the extremely thin coating can impregnate the whole fabric by penetrating into the fabrics pores without obstruct these, which means that the breathability of the fabric is maintained.
