  • Polyurethane elastomers are segmented cocoplymer with an [HS]n-type structure. Typically, these materials are two-phase systems, prepared from relatively polar and stiff component called the hard segment(H) and relatively flexible component known as the soft segment(S). Diisocyanate and chain extender together form the hard segment, which is dispersed within a matrix of the soft segment, composed of the macrodiolos.(omitted)

  • Waterborne Polyurethane dispersions continue to show growth in commercial usage due to the ever increasing environmental legislation to reduce VOC in Coating and adhesive materials. The transition from solvent-based to waterborne Polyurethane(WPu) has also been facilitated by advances in both the chemistry and technology employed and the formulation expertise required.

  • The domestic textile industry is currently making an active effort to present high value-added materials that can respond immediately to the wants and needs of consumers sensitive to the of originality of design and emotionally appealing fashion materials. This paper attempted to present the creative development of materials in the contemporary clothing culture in which consumers' needs are individualized and differentiated and the cycle of life in fashion materials is getting shorter. To be specific, the paper presented the texture of peculiar expression to diverse cotton materials using the Woolsmok technique in the processing of felt. The chosen Merino wool was felted to 8 kinds of cotton with different density and structure. The touch, texture, visibility and complex susceptibilities of new materials were presented as different materials of cotton and wool were transformed into one material. In felting cotton fiber through wool, the transformation of diverse textures was presented and compared in the method using the washing machine in an attempt to enhance the efficiency of the traditional craft technique and work. This study proposed the possibility of placing the new material made up of cotton and wool beyond the range of functionality of each simple material, activating it as the peculiar material and expanding it to the range of its use as fashion material in the clothing industry. It is expected that this material will become competitive material at home and abroad by being activated as the clothing material of artistry, workability and marketability that can satisfy the tastes of consumers who call for high quality and diversification.

  • A new class of materials based on organic and inorganic species combined at a molecule level has obtained more attention recently[1]. HPA(heteropolyacid) shows unmatched applied perspective in terms of synthesis chemistry, analysis chemistry, biology, medicine and materials science[2]. As a potential photochemical material, the hybrid system of HPA and polymer has been investigated. However, the design and synthesis of heteropolyacid-based hybrids, which are at the forefront of the materials chemistry research, is still in its infancy. (omitted)
