“…As shown in Figure , the nanokeratin film presented a dense and compacted structure which was held by the strong hydrogen network established between the hydroxyl groups present on the keratin chains. WVP of the nanokeratin film was 4.53 ± 1.15 e −14 (kg m s −1 m −2 Pa −1 ), which was similar to that previously reported for hydrophilic films such as sodium caseinate and starch . However, it was not possible to measure; it provided an average in the test, the oxygen permeability of the pure nanokeratin films since the material partially disintegrated when subjected to the high relative humidity conditions (80% RH) used for the standard oxygen permeability measurements.…”

This work reports on the combination of polyhydroxyalkanoate (PHA)‐based materials and nanokeratin extracted from poultry feathers (a food by‐product) using different approaches. In the first approach, high‐barrier nanobiocomposites based on the combination of PHAs with a nanokeratin additive were successfully developed via both (i) direct melt compounding and (ii) preincorporated into an electrospun masterbatch of PHA which was subsequently melt compounded with PHA pellets. Enhanced barrier properties for the nanobiocomposites were obtained which were seen to depend on the PHA grade used. In the second approach, nanokeratin films were obtained via solution casting which were successfully hydrophobized by coating them with electrospun PHA fibers. The multilayered approach showed good adhesion and also lead to enhanced barrier performance. © 2015 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 42695.

Regarding the growing interest in the development of biodegradable films from renewable sources, this work is focused on the utilization of cassava roots bagasse as a natural filler of cassava starch films. Homogenous films could be obtained by casting molding from gelatinized cassava starch suspensions, plasticized with glycerol and containing 1.5% w/w bagasse. In order to study the particle size effect on films properties, three different fibrous residue fractions (particles sized between 500–250, 250–53, and particles <53 μm) were used and compared to films reinforced with bagasse particles sized under 500 μm. Chemical composition and particle size distribution of cassava bagasse helped to explain the starch films morphology and mechanical and barrier properties modifications. SEM micrographs evidenced that the filler was structurally incorporated in the matrix, reinforcing cassava–starch matrices regardless of bagasse particle size. The filler increased the UV-barrier capacity and opacity of the materials, though water vapor permeability increased with solids content and filler particle size. Moreover, the developed biocomposite materials can be heat-sealed, indicating their suitability for flexible packaging manufacture. Even though starch-based materials are essentially biodegradable, the biodegradation kinetics of the reinforced biocomposites was studied showing the slowest degradation process for materials with larger filler particles.

Anahtar kelimeler Biyopolimerler Endüstriyel polimerler Ambalaj sektörü Doğal ve sürdürülebilir kaynaklar Özet Polimerler; istenilen özellikte sentezlenebilme, kolay işlenebilme, korozyona uğramama, hafiflik ve düşük maliyete sahip olma gibi özelliklere sahip gelişmiş materyallerdir. Sahip oldukları bu özellikler sayesinde polimerler, endüstride birçok kullanım alanı bulmuştur ve bu alanlar gün geçtikçe artmaktadır. Endüstriyel polimerler göstermiş oldukları yüksek potansiyel ve özelliklerin aksine, doğal bir süreç ile yok edilememesi sonucu kirlilik oluşturmakta ve ancak maliyetli parçalanma işlemleri sonucunda bertaraf edilebilmektedir. Bununla birlikte, petrol kaynakları gibi tükenir kaynaklardan elde edilmeleri, polimer sektöründe süreklilik ve çevre uyumu açısından yeni arayışlara yol açmıştır. Biyopolimerler, endüstriyel polimerlerin tükenir kaynaklardan elde edilmeleri ve bertarafının zor olması gibi dezavantajları sonucu, başta ambalaj sektörü olmak üzere birçok alanda alternatif materyal olarak ön plana çıkmıştır. Doğal ve sürdürülebilir kaynaklardan elde edilen biyopolimerler, mekanik ve termal özellikleri sayesinde endüstriyel polimerlerin taşıdığı özelliklere eşdeğer özelliklerde olup; biyopolimerlerin ilerleyen yıllarda polimer endüstrisinde önemli bir yere sahip olacağı öngörülmektedir. Bu derleme çalışmasında biyopolimerin çeşitleri hakkında bilgiler verilmiş ve sektörlere göre kullanım alanları incelenmiştir.
