Amorf polimerler, moleküllerin düzenli ve yapılandırılmış bir düzenlemesine sahip olan kristalli polimerlerin aksine, rastgele ve düzensiz bir molekül düzenlemesine sahiptir. Amorf polimerler, kristal bir yapıya sahip olmadıklarından daha esneklerdir. Bu malzemeler grubu şeffaflık, esneklik ve darbe direncinin önemli olduğu uygulamalarda kullanılmaktadır. Kristal yapıya sahip olmadıkları için ışığı dağıtmazlar, bu da onları lensler veya ekranlar gibi optik netliğin önemli olduğu uygulamalarda kullanım için ideal kılmaktadır. Amorf polimerlerin yapı eksiklikleri, işlemede tekdüzelik elde etmeyi zorlaştırabileceğinden, işlenmeleri kristal polimerlere göre daha zor olabilmektedir. Ayrıca kristal polimerlerden daha düşük erime noktalarına sahip olduklarından yüksek sıcaklıklarda deformasyona veya erimeye karşı daha duyarlıdırlar. Teknoloji ilerledikçe ve yeni malzemeler geliştirildikçe, amorf polimerler, ambalajdan elektroniğe ve tıbbi cihazlara kadar uzanan endüstrilerde büyük olasılıkla önemli rol oynamaya devam edecektir. Bu makale kapsamında amorf ve kristalin polimerlerin yapısı ve çeşitleri araştırılmış, kıyaslamalı bir şekilde polimerlerdeki amorf ve kristalin düzen incelenmiş, polimerlerin genel olarak sınıflandırılması yapılmış ve fiziksel özelliklerine de yer verilmiştir.

AMORPHOUS POLYMERS

Öz

Amorphous polymers have a random and disordered arrangement of molecules, unlike crystalline polymers, which have an ordered and structured arrangement of molecules. Amorphous polymers are more flexible as they do not have a crystalline structure. This material group is used in applications where transparency, flexibility and impact resistance are important. Because they do not have a crystalline structure, they do not scatter light, making them ideal for use in applications where optical clarity is important, such as lenses or displays. Amorphous polymers can be more difficult to process than crystalline polymers, as the structural deficiencies can make it difficult to achieve uniformity in processing. Also, since they have lower melting points than crystalline polymers, they are more susceptible to deformation or melting at high temperatures. As technology advances and new materials are developed, amorphous polymers will likely continue to play an important role in industries ranging from packaging to electronics to medical devices. Within the scope of this article, the structure and types of amorphous and crystalline polymers were investigated, and they have been included in the article in a comparative way. The amorphous and crystalline order in the polymers was investigated. Polymers have been broadly classified and their physical properties have been studied.
