µPlasma Patterning and Inkjet Printing to enhance localized wetting and mixing behaviour

Dr. Ir. M.H.A. van Dongen (Docent)

With a market demand for low cost, easy to produce, flexible and portable applications in healthcare, energy, biomedical or electronics markets, large research programs are initiated to develop new technologies to provide this demand with new innovative ideas. One of these fast developing technologies …

Development of breathable hydrophobic/hydrophilic functional textiles

Agrawal, P. (Pramod) (Researcher); Brink, G.J. (Ger) (Lector)

The proposed bi-functional protective structure intended to have hydrophilic interior towards the skin surface and hydrophobic exterior for protection, ensuring fast transfer of moisture between body and external environment. The sandwich structure is prepared using 100% wool jersey and varieties of …

Digital printing of μPlasmas to selectively improve wetting behavior of functional inks for printed electronics

M.H.A. van Dongen (Docent); E. Nieuwenhuis (Onderzoeker); L. Verbraeken (Onderzoeker); R. verkuijlen (Lid Lectoraat); P. Ketelaars; J.P.C. Bernards (Lector)

In this article we investigate the change in wetting behavior of inkjet printed materials on either hydrophilic or hydrophobic plasma treated patterns, to determine the minimum obtainable track width using selective patterned μPlasma printing. For Hexamethyl-Disiloxane (HMDSO)/N2 plasma, a decrease in …

µPlasma printing of hydrophobic and hydrophilic patterns to improve wetting behaviour for printed electronics

ir.M.H.A. van Dongen (Lid Lectoraat); E. Nieuwenhuis (Student); L. Verbraeken (Student); ir. R.O.F. Verkuijlen (Lid Lectoraat); dr. J.P.C. Bernards (Lector)

Inkjet printing is a rapidly growing technology for depositing functional materials in the production of organic electronics. Challenges lie among others in the printing of high resolution patterns with high aspect ratio of functional materials to obtain the needed functionality like e.g. conductivity. …

Surface and Bulk Modification of Synthetic Textiles to Improve Dyeability

Agrawal, P. (Pramod) (Researcher); Parvinzadeh Gashti, M. (M) (Researcher); Willoughby, J. (J) (Researcher)

Synthetic fibers, mainly polyethylene terephthalate (PET), polyamide (PA), polyacrylonitrile (PAN) and polypropylene (PP), are the most widely used polymers in the textile industry. These fibers surpass the production of natural fibers with a market share of 54.4%. The advantages of these fibers are …

Cyclohexane-based low molecular weight hydrogelators

Friggeri, Arianna; van der Pol, Cornelia; van Bommel, Kjeld J C; Heeres, André (Biobased Ingredients And Materials); Stuart, Marc C A; Feringa, Ben L; van Esch, Jan

Seven new 1,3,5-cyclohexyltricarboxamide-phenylalanine derivatives were synthesized in order to investigate the effect of the amino acid chirality on the gelating properties of these small molecules in water. Gelation tests have shown that enantiomerically pure homochiral 1,3,5-cyclohexyltricarboxamide-L-phenylalanine …

Responsive cyclohexane-based low-molecular-weight hydrogelators with modular architecture

van Bommel, Kjeld J C; van der Pol, Cornelia; Muizebelt, Inouk; Friggeri, Arianna; Heeres, André (Biobased Ingredients And Materials); Meetsma, Auke; Feringa, Ben L; van Esch, Jan

pH-sensitive gels: By using a cyclohexane-based scaffold to which various amino acid based substituents can be connected, low-molecular-weight compounds were obtained that can gelate water at very low concentrations. Their modular design (see picture: AA = amino acid(s), X = hydrophilic substituent, …
