Abstract

Smart materials are a family of materials that are listed in advanced materials. These groups of materials have self-accommodation with environment and they are classified according to their responses, such as physical (pressure, temperature, humidity, light, electric field, magnetic field), chemical (pH, CO2, etc.), or biological stimuli. The smart materials can convert the absorbed energy or their characteristics may undergo a change. Smart materials are getting high attentions due to their commercial applications in either actuator or sensor form. This work demonstrates an exclusive review of different types of smart materials with their specific characteristics, and some related investigations that improved smart material properties. In addition, the applications of smart materials are categorized according to the different application areas, such as medical implantation, reducing waste, and nano engineered systems.

Akıllı Malzemeler üzerine derleme: araştırmalar ve uygulamaları

Abstract

Akıllı malzemeler, ileri malzemeler grubunda yeralan, bir malzeme grubudur. Bu malzeme grupları, çevresi ile kendi kendine uyum içindedir ve bazı fiziksel (basınç, sıcaklık, nem, ışık, elektrik alan, manyetik alan), kimyasal (pH, CO2 vb.) veya biyolojik uyarılara verdikleri tepkilere göre sınıflandırılırlar. Akıllı malzemeler, soğurulan enerjiyi, karakteristik özelliklerini değiştirmek için dönüştürürler. Akıllı malzemeler, aktüatör veya sensör şeklindeki ticari uygulamaları nedeniyle yüksek oranda dikkat çeker. Bu çalışma, farklı türdeki akıllı malzemelerin spesifik özellikleriyle birlikte özel bir incelemesini ve akıllı malzemelerin özelliklerini iyileştiren bazı ilgili araştırmaları göstermektedir. Ayrıca, akıllı malzemelerin uygulamaları, tıbbi implantasyon, atıkları azaltma ve nano mühendislik sistemleri gibi farklı uygulama alanlarına göre kategorilere ayrılmaktadır
