1. 1. Deacetylated Hyaluronan : Exploration of deacetylation techniques for hyaluronan (oligo and polysaccharides)

   University essay from Uppsala universitet/Institutionen för materialvetenskap

   Author : Sima Mardini; Hanna Björk; Marcus Möller; Carl Lagergren; Oscar Samuelsson; [2023]
   Keywords : hyaluronic acid; deacetylated hyaluronan; N-deacetylation; re-acetylation; hydrogels;

   Abstract : Hyaluronic acid is an organic polysaccharide with a wide range of uses in medical and cosmetic industries due to its physiological properties. Crosslinked hyaluronic acid is a commonly used filler agent because of its water retention capabilities. N-deacetylation can be performed to enable new derivatives of hyaluronic acid. READ MORE

3. 2. Development of corrosion resistant coatings using natural biopolymer and pollen

   University essay from KTH/Materialvetenskap

   Author : Alessandro Armani; [2020]
   Keywords : ;

   Abstract : Corrosion is a mechanism that highly reduces the lifetime of metals in different environments, especially in water or moisture environment. The worldwide maintenance cost due to corrosion is estimated in billions of dollars per year, and actual solutions in terms of coating usually contains toxic or environmentally harmful species.

4. 3. A novel chitosan-stearic coating with bee-pollen microcapsules for corrosion protection

   University essay from KTH/Materialvetenskap

   Author : Albin Andersson; [2020]
   Keywords : ;

   Abstract : In this project a novel chitosan-stearic acid (CS-SA) coating with bee-pollen microcapsules for encapsulation of 2-mecraptobenzothiazole (MBT) as a waterborne formulation for a biocompatible corrosion protection coating was developed and the coating properties was analyzed. Hydrophobic stearic acid (SA) was crosslinked with via a carbodiimide reaction to form micelles and is assembled on the bee- pollen grains and the chitosan matrix was further self-crosslinked using glutaraldehyde (GA).

5. 4. A Study of Various Parameters Affecting Adhesion of Coatings to Metal Substrates

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Worabhorn Pathanatecha; [2019]
   Keywords : adhesion; coatings; metal substrates; silanes; polyurethanes; surface energy; crosslinking agent; adhesion promoters; vidhäftning; beläggningar; metallunderlag; silaner; polyuretaner; ytenergi; tvärbindningsmedel; vidhäftningspromotor;

   Abstract : The adhesion of coatings is of high importance in the coating industry and a more thorough understanding of adhesion behavior is required. In this thesis work, seven parameters affecting adhesion of silane-modified poly(urethane urea) (PUSi) coatings on pretreated steel and aluminum substrates were studied. READ MORE

6. 5. Enhancing the durability of fluorocarbon-free Durable Water Repellant (DWR) formulation

   University essay from KTH/Skolan för kemivetenskap (CHE)

   Author : Meron Solomon; [2017]
   Keywords : Hydrophobicity; textile coating; cross-linker; nanoparticles; surface roughness;

   Abstract : The focus of the project was to alter and optimize the water repellant textile coating formulations to reach enhanced durability. For this purpose, the project was approached with three methods. Firstly, bio-based components were implemented in the mother emulsion to act as surfactant and crosslinking agent and to provide hydrophobic properties. READ MORE
