   University essay from KTH/Fiber- och polymerteknologi

   Author : Anna Gardell; Maria Aspenberg; Julia Aziz; [2022]
   Keywords : vanillin; vitrimer; imine; resin; dynamic covalent bonds; biobased thermoset; photocuring; chemical recyclability; self-healing; digital light processing DLP ; 3D-printing; vanillin; vitrimer; imin; resin; dynamiska kovalenta bindningar; biobaserad härdplast; fotohärdning; kemisk återvinningsbarhet; självläkning; digital light processing DLP ; 3D-utskrift;

   Abstract : Överkonsumtionen av engångsartiklar i fossilbaserad plast är ett av dagens stora miljöproblem. Således finns en efterfrågan på strategier för framställning av biobaserade plaster i allmänhet och härdplaster i synnerhet. READ MORE

3. 2. Recyclability by Design for Multilayer Plastic Flexible Packaging

   University essay from Lunds universitet/Förpackningslogistik

   Author : Sonika Singh; [2020]
   Keywords : Recyclability by design; multilayer flexible packaging; PE; PP; plastic recycling; circular plastic economy; Technology and Engineering;

   Abstract : Various recyclability by design (RBD) guidelines for multilayer plastic flexible packaging (MPFP) were assessed for consistency among parameter values. 9% consistency was observed, which is on the lower end of devised consistency scale. READ MORE

4. 3. Effects of processing techniques on the microstructure of renewable pulp-fiber reinforced composites and their mechanical performance

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Predrag Jagunic; [2018]
   Keywords : composites; mechanical performance; microstructure; renewable; processing techniques;

   Abstract : Commingled composites are stronger than those manufactured with the standard manufacturing method. The objective of the thesis is to answer why that is, to investigate the microstructure of the composites, to model composite strength and compare experimental values with theoretical for composites having poly lactic acid (PLA) as matrix material and composites having poly propylene (PP) as matrix material.

5. 4. Polymeric single Li+-ion conductors: preparation and characterisation

   University essay from Lunds universitet/Centrum för analys och syntes

   Author : Hannes Nederstedt; [2016]
   Keywords : single ion conductors; electrolytes; polymers; lithium ion batteries; polymer technology; polymerteknologi; Chemistry; Technology and Engineering;

   Abstract : Lithium-ion batteries are a common type of light-weight, rechargeable batteries. There are safety concerns because these batteries typically use an organic solvent electrolyte which presents fire hazards. By using dry polymer electrolytes, the fire hazards can be eliminated.

6. 5. Shear and Tensile Fracture Analysis of HDPE and PP-Experimental Results Combined with Simulation

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Md. Shafiqul Islam; Abdullah Khan; [2013]
   Keywords : MSYM; Fracture toughness; energy release rate; Abaqus; Poly Propylene; High Density Polyethylene;

   Abstract : For the past many years, packaging have been designed just to preserve food items and to catch the attention of the customers by concentrating on the design rather than making it easy to open. But now companies like Tetra Pak are focusing on the flexibility of packaging design by making it user friendly without compromising the design quality. READ MORE
