Caffeine adsorption by using cyclodextrin hydrogel
Collection: Theses (Master's degree) - Polymer Science and Engineering / วิทยานิพนธ์ - วิทยาการและวิศวกรรมพอลิเมอร์Type: Thesis(Silpakorn University, 12/7/2019)Caffeine is found in various kinds of food and drink and it can affect the human nervous system. This research aims to prepare the hydrogel between cellulose and β-cyclodextrin from co-precipitation and crosslink method. ... -
Development of Bio-based Epoxy Materials from Vegetable Oil
Collection: Theses (Master's degree) - Polymer Science and Engineering / วิทยานิพนธ์ - วิทยาการและวิศวกรรมพอลิเมอร์Type: Thesis(Silpakorn University, 4/7/2023)Epoxy material from vegetable oil has more attention because of its environmental friendliness. In present research, a bio-based epoxy resin formulated from the crosslinking reaction between epoxidized linseed oil and ... -
Influence of linseed oil and its derivative on moisture absorption and mechanical properties of thermoplastic starch
Collection: Theses (Master's degree) - Polymer Science and Engineering / วิทยานิพนธ์ - วิทยาการและวิศวกรรมพอลิเมอร์Type: Thesis(Silpakorn University, 12/7/2019)Thermoplastic starch (TPS) is a bio-based and biodegradable polymer that has tendency to replace many petroleum-based polymers. However, one of the important weakness of TPS is moisture sensitivity. This research aims to ... -
Study on preparation and absorption of hydrophilic-hydrophobic hydrogels
Collection: Theses (Master's degree) - Polymer Science and Engineering / วิทยานิพนธ์ - วิทยาการและวิศวกรรมพอลิเมอร์Type: Thesis(Silpakorn University, 18/6/2021)The hydrogel is a three-dimensional structure material made from hydrophilic polymers. Hydrogel, therefore, can absorb and contain a lot of water. The primary aim of the present work is to develop the elastic porous ... -
study on preparation and water absorption of cellulose / oligo-chitosan hydrogel
Collection: Theses (Master's degree) - Polymer Science and Engineering / วิทยานิพนธ์ - วิทยาการและวิศวกรรมพอลิเมอร์Type: Thesis(Silpakorn University, 18/6/2021)Water-absorbing materials can be synthesized from hydrophilic polymers. Cellulose and chitosan are the natural polymers, which have a potential to prepare water-absorbing materials. The conventional cellulose/oligo-chitosan ...
