3. 7. Poly(ethylene-graft-ethylene oxide) Preparation and Properties in Polymer Blends

   Författare :Åsa Halldén; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Surface modification; Graft copolymers; Polymer blends; Polyethylene; Polyethylene oxide; Polyamide; Polymer technology; biopolymers; Polymerteknik;

   Sammanfattning : This thesis describes the preparation, characterisation and properties of poly(ethylene-graft-ethylene oxide) (PE-PEO). The grafting reaction was carried out with the grafting onto method using the carboxylic acid groups of poly(ethylene-co-acrylic acid) (PEAA) as reactive sites in an esterification reaction with poly(ethylene oxide) mono-methyl ethers (MPEO) of varying molecular weights: 750, 2000 and 5000.

4. 8. Melt Spun Electro-Conductive Polymer Composite Fibers

   Författare :Azadeh Soroudi; Högskolan i Borås; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; conductive fibres; composites; blending; melt spinning; morphology; polyaniline; carbon nanotube; polypropylene; polyamide; draw-ratio; conductivity; Energi och material;

   Sammanfattning : One interesting approach is the development of conductive polymer composite fibers for innovative textile applications such as in sensors, actuators and electrostatic discharge. In this study, conductive polymer composite fibers were prepared using several different blends containing conductive components: a conjugated polymer (polyaniline-complex) and/or carbon nanotubes.

5. 9. Material development of a textile bioreactor : All-polyamide composite for the construction of bioreactors

   Författare :Mostafa Jabbari; Mikael Hedenqvist; Högskolan i Borås; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; textile bioreactor; biofuel; coated fabric; all-polyamide composite; polyvinyl chloride PVC ; solvent replacement; Hansen solubility parameters HSPs ; Resource Recovery; Resursåtervinning;

   Sammanfattning : Bioreactors are manufactured from stainless/carbon steel, concrete, glass, etc., which are costly and time-consuming to install. Recently, several research studies have been initiated to find cost-efficient materials for constructing bioreactors, one of which is coated textiles. LÄS MER

7. 10. Solid-Phase Microextraction in Polymer Analysis - Extraction of Volatiles from Virgin and Recycled Polyamide 6.6

   Författare :Mikael Gröning; Minna Hakkarainen; Stephen Kelley; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; polymer; polyamide 6.6; volatiles; emissions; degradation; quantitation; Kemi; Chemistry; Kemi;

   Sammanfattning : The extraction and quantitative analysis of low molar mass compounds in polymers is an analytical challenge. It is also important from a practical point of view because the low molar mass compounds in time will migrate from the polymers into the surrounding environment. LÄS MER
