Synthesis and Characterizations of Polyurethane Based Coatings Containing Telechelic Siloxane Oligomers
Öz
Polyurethanes (PU) are a large family of polymers that have urethane bonds formed as a result of the reaction of diisocyanate and diol monomers in their main chain. Telechelic siloxane oligomers (TSO) are unique materials that have various reactive functional groups at their end groups and can chemically bond from these functional groups with various oligomer blocks, allowing to obtain block copolymers that can be used in many applications depending on their molecular weight and composition. In this study, Polyurethane/Polydimethylsiloxane (PU/PDMS) multiblock copolymers were synthesized by using telechelic Polydimethylsiloxane (PDMS) oligomers. Basic functional properties such as insulation and adhesion performance of PU/PDMS-based materials intended to serve as coating material were determined. Also hardness, mechanical and thermal characteristics, and combustion behaviors of PU/PDMS based coatings were examined and the optimum composition was determined by revealing the structure-property relationship as a result of the examinations carried out.

Telekelik Siloksan Oligomerleri İçeren Poliüretan Esaslı Kaplamaların Sentezi ve Karakterizasyonları
Öz
Poliüretanlar (PU) diizosiyanat ve diol monomerlerinin reaksiyonu sonucu oluşan üretan bağlarını ana zincirinde barındıran geniş bir polimer ailesidir. Telekelik siloksan oligomerleri (TSO) uç gruplarında çeşitli reaktif fonksiyonel gruplar taşıyan ve bu fonksiyonel gruplar ile oligomerik yapıdaki farklı polimer bloklarıyla kimyasal olarak bağlanarak, molekül ağırlıkları ve ana zincirdeki bileşimlerine bağlı olarak pek çok uygulamada görev alabilecek blok kopolimerlerin eldesine imkân sağlayan eşşiz malzemelerdir. Çalışmada telekelik Polidimetilsiloksan (PDMS) oligomerlerinin kullanımı ile Poliüretan/Polidimetilsiloksan (PU/PDMS) multiblok kopolimerleri sentezlendi, kaplama malzemesi olarak görev yapması hedeflenen PU/PDMS esaslı malzemelerin bu fonksiyonu yerine getirirken sağlaması gereken en temel fonksiyon özellik olan yalıtım, yapışma performansları başta olmak üzere sertlik özellikleri, mekanik ve termal karakteristikleri ile yanma davranışları belirlenerek, gerçekleştirilen incelemeler sonucu yapı-özellik ilişkisi ortaya konarak en uygun bileşimin belirlenmesi sağlandı.
