  2. 1. Ink Jetting of Photochromic Ink : Towards the Design of a Smart Textile Sensor

    Author : Sina Seipel; Högskolan i Borås; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inkjet printing; UV curing; photochromic; UV-sensing; smart textile; resource-efficient; scCO2 dyeing; jetting; dye kinetics; color performance; durability; stabilization; Textil och mode generell ; Textiles and Fashion General ;

    Abstract : Smart textiles have been a hot topic in research for several decades; however, comparatively few products can be found on the market. Resource-efficient processes can boost the breakthrough of smart and functional textiles, which often necessitate high-cost materials and only require small batches. READ MORE

    Abstract : The demand for functional and smart textiles has risen nowadays due to the lifestyle change of human beings. Along with this, the production of functional and smart textiles is consistently increasing. READ MORE

  5. 3. Foam, Fire and Free Volume - Chemical and Physical Aspects of Porous Polymers

    Author : Anna Andersson; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Poisson ratio; vibration damping; acoustic impedance; cell morphology; hyperbranched polymer; Polymer foams; free volume; positron annihilation; supercritical fluid.;

    Abstract : Automotive seating has been under continous development since it was described for the first time in 1885. At that time one could read about a “padded leather bench seat sitting on springs mounted directly to the frame of a horse-less carriage”. READ MORE

  6. 4. Superhydrophobic coatings of wax and polymers sprayed from supercritical solutions

    Author : Louise Ovaskainen; Lars Wågberg; Charlotta Turner; Eric Beckman; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; superhydrophobic coatings; polymer; wax; supercritical carbon dioxde; RESS; Chemical Engineering; Kemiteknik;

    Abstract : The possibility of using supercritical carbon dioxide (scCO2) as the primary solvent in a spray process for producing superhydrophobic surfaces have been examined in this work. Using scCO2 as solvent will have considerably lower environmental impact compared to an organic solvent since scCO2 is considered a green solvent as it is non-toxic, non-flammable and recyclable.
