Her alanda etkin ve ilerici değişikliklerin oluşturulmasında itici bir güç olan nanoteknoloji, orman ürünleri sektöründe de kendine yer bulmaya başlamıştır. Özellikle son yıllarda nanobilimi, malzeme bilimi ve orman ürünleri biliminin multidisipliner bir yapı ile ortaklaşa çalışması yeni nesil kompozit malzemelerin, biyokompozitlerin ve nanokompozitlerin geliştirilmesinde büyük rol oynamıştır. Geliştirilen bu inovatif malzemeler geleneksel malzemelerin yerini almakta ve geleneksel üretim tekniklerinin, makinelerinin de rollerini değiştirmesini ve kendini güncellemesini sağlamaktadır. Ağaç malzemenin bileşenlerinden birisi olan selüloz kendi içerisinde birbirine bağlı nano boyutta yapıtaşlarına sahiptir. Nanoselüloz adı verilen bu yapıtaşları saç kalınlığının yaklaşık 10 binde biri küçüklüğünde lifleri ve partikülleri içermektedir. Nanoselüloz ağaç malzemeye mekaniksel gücünü veren doğal, yenilenebilir ve mucizevi bir polimerdir. Doğal polimerik yapısı birçok uygulamada kullanılmasına olanak sağlayan nanoselüloz günümüzde otomotiv, elektronik, inşaat ve ambalajlama gibi sektörlerde kullanılmaya başlanmıştır. Nanoselüloz, hafif olmasına karşın sağladığı yüksek performans özellikleri ile endüstri ve akademi tarafından ilgi gören, geleceğin değerli malzemelerinden birisi olarak kendine yer oluşturmaya başlamıştır. 

Bu çalışmada, nanoteknoloji ve geleceğin malzemesi nanoselüloz hakkında son yıllarda yapılmış çalışmalardan detaylı bilgiler derlenmiş ve söz konusu malzemelerin türleri, üretim teknolojileri, küresel üreticileri ve gelecekteki kullanım alanları hakkında teknik bilgiler paylaşılmıştır.

The nanotechnology that produced innovative changes in many industries has been getting attention in the forest products industry as well. Especially, the increase in multidisciplinary studies motivated researchers to work and study on new-generation nanocomposites and biocomposites that will be a strong alternative to traditional materials with the value-added properties. The cellulose, a crucial component of the trees, is made of small blocks. These blocks which are called nanocellulose contain fibrils and particles. Nanocelluloses are green polymers that have received considerable attention in materials science, engineering research, and research & product development fields in the industry. Nanocellulose is a bio-nano polymer that is widely used as reinforcing materials and added to polymer matrices to create innovative nanocomposites for use in many industries. Today, nanocellulose materials have been used in automotive, packaging, pharmaceutical, insulation and construction industries. The enhancements in the nanocellulose manufacturing processes, the increase in the number of global producers, and the increased demand for green and eco-friendly materials have made the nanocellulose more attractive for the industry and the institutions. 

In this study, a concise, critical state-of-the-art review on nanocellulose materials, manufacturing technologies, global producers and their current and future applications were studied and reported.
