“…Cellulose, the most abundant renewable biopolymer, has been incorporated into a wide range of consumer products in various forms. Cellulose's unique characteristics include, but are not limited to, surface chemical reactivity, biocompatibility, low toxicity, and mechanical properties [3][4][5][6][7][8][9][10]. Nanocellulose, as an example of cellulose forms, is produced after raw cellulosic material has undergone chemical and/or mechanical processes.…”

Evaluation of Acetaminophen Release from Biodegradable Poly (Vinyl Alcohol) (PVA) and Nanocellulose Films Using a Multiphase Release Mechanism

Biodegradable polymers hold great therapeutic value, especially through the addition of additives for controlled drug release. Nanocellulose has shown promise in drug delivery, yet usually requires chemical crosslinking with harsh acids and solvents. Nanocellulose fibrils (NFCs) and 2,2,6,6-tetramethylpiperidine-N-oxyl (TEMPO)-mediated oxidized nanocellulose fibrils (TNFCs) with poly (vinyl alcohol) (PVA) could be aqueously formulated to control the release of model drug acetaminophen over 144 h. The release was evaluated with a multiphase release mechanism to determine which mechanism(s) contribute to the overall release and to what degree. Doing so indicated that the TNFCs in PVA control the release of acetaminophen more than NFCs in PVA. Modeling showed that this release was mostly due to burst release-drug coming off the immediate surface, rather than diffusing out of the matrix.

The change in the properties of low-density polyethylene after adding starch, oxo-material, polylactic acid, and their mixture was studied. Different amounts of the additives were added, and films were prepared by using a twin-screw extruder at 150-225 C. By Minitab software, the optimum percentages of the additives were selected. The films were kept under different environmentalconditions including "open atmosphere," "buried underground," and "buried underground with regular daily irrigation" for 6 months. The degradability, tensile strength, elongation at breaking point, and dart impact were measured. Thermogravimetric analysis and FTIR spectrum changes were used to monitor changes. SEM images illustrated that the starch changed the morphology significantly, while other additives did not show remarkable effects. Mechanical and chemical properties changed significantly when starch was added. The highest changes were recorded for the sample with three additives, which was showing the high efficiency of the film decomposition. The highest amount of chemical changes was recorded for the same film. After 6 months, the lowest crystallinity was recorded by DSC and XRD for the same sample. Different environmental conditions showed different effects on the films mechanical properties. However, chemical properties of the films, excluding the film with starch, did not change significantly.

“…Although many studies have been performed to understand the properties of RPUFs reinforced with nanocellose, most of those studies were conducted using nanocrystalline cellulose (CNC) obtained via hydrolysis . Some recent investigations using BNC have shown that BNC can be incorporated into solid polyurethane composites to improve the mechanical properties; however, the effect of incorporating BNC into RPUFs has barely been studied.…”

Nanocellulose reinforced foams are lightweight with improved mechanical properties; however, the strain‐rate effect on their mechanical response is not yet fully understood. In this work, rigid polyurethane foams (PUFs) nanostructured with bacterial nanocellulose at 0.2 wt % (BNCF) and without it (PUF) are synthesized and subjected to compression tests at different strain rates. The BNC acts as a nucleation agent, reducing the cell size but maintaining a similar apparent density of 40.4 ± 3.3 kg m−3. Both BNCF and PUF exhibit strain‐rate effect on yield stress and densification strain. The BNCF exhibits localized progressive crushing and reduced friability, causing a remarkable recovery in the transverse direction. Numerical simulations show that functionally graded foams subjected to impact could be designed using different layers of PUF and BNCF to vary energy absorption and acceleration rate. The results presented herein warrant further research of the mechanical properties of nanostructured foams for impact applications. © 2019 Wiley Periodicals, Inc. J. Appl. Polym.
