“…Broken fibers have been detected in all compositions, thus revealing some degree of interaction between the cellulose and the biopolyesters. This is in agreement with previous results and could be attributed to the formation of a hydrogen‐bonding‐type interaction between carbonyl groups of PHBV and hydroxyl groups of the cellulose . However, when analyzing the interphase, as for the TPU second phase, some detachment is also detected at some point, revealing a weak interphase interaction.…”

Poly(hydroxybutyrate‐co‐valerate) (PHBV) is a biopolymer that has gained a lot of attention because of its biodegradability, good thermal resistance, and balanced mechanical properties with respect to some commodity plastics. However, it presents two big limitations that hinder its potential application in replacing plastics for rigid injected parts: high cost and low toughness. Aiming at overcoming these limitations, the use of two additives in a PHBV matrix was explored: thermoplastic polyurethane (TPU) as an impact modifier and cellulose as reinforcing filler. Compounds of PHBV with different TPUs and cellulose contents were prepared by extrusion and, subsequently, injection molding. The morphology, thermal, and mechanical properties of the so‐obtained materials were analyzed. Also, the biodisintegrability under standard composting conditions of the studied compositions was also assessed. The results of this work show that the obtained PHBV/TPU/cellulose compounds are biodisintegrable and show balanced properties in terms of thermal resistance–stiffness–toughness. These properties point these compounds as potential candidates to replace commodities in rigid part applications that require biodisintegration in their end‐of‐life, being able to be processed in a conventional injection molding industrial facility. © 2018 Wiley Periodicals, Inc.

“…The samples show the peaks at 1,732 and 1,697 cm −1 corresponding to the stretching vibration of free and hydrogen bonded C = O, respectively .The hydrogen bonds fraction of C = O ( F H–CO ) can be calculated using the following Equation [13]:

F_{H - CO} = \frac{A_{normalH} / r}{A_{normalH} / r + A_{normalf}} = \frac{A_{normalH}}{A_{normalH} + r A_{normalf}}

where A H and A f are the peak areas of hydrogen bonded C = O and free C = O, respectively. The r stands for the specific absorption ratio of the above two bands, which is 1.5 for hydrogen bonding carbonyl groups . The F H‐CO of XNBR–BCWs nanocomposites are evaluated and shown in Table .…”

Water-induced mechanically adaptive rubber nanocomposites were prepared by mixing bacterial cellulose whiskers (BCWs) suspension with carboxylated acerlonitrilebutadiene rubber (XNBR) latex, followed by latex blending method. The introduction of BCWs into XNBR enhanced the tensile storage modulus (E') significantly, which originated from the formation of a rigid 3D filler network within matrix as well as the interfacial interaction between filler and matrix. The water uptake ratio of nanocomposite films increased with BCWs content, from 5.5% for neat XNBR to 54% for nanocomposite with 20 phr (parts per hundred rubber) BCWs. Upon submersed in water, the nanocomposite films showed dramatic decrease in E 0 , especially for which filled with high BCWs loadings. For example, E 0 of nanocomposite with 20 phr BCWs was decreased by 98.04% after equilibrium swelling compared with only 52.02% for nanocomposite with 3 phr BCWs. The remarkable watertriggered modulus changes are attributed to the disentanglement of BCWs network after swelling. The prepared XNBR-BCWs nanocomposites with mechanically adaptive properties could contribute to develop the new type of rubber-based smart materials. POLYM. ENG. SCI., 00:000-000, 2018.

“…[27,28] Furthermore, the processing of cellulose using ILs were also reported; for example, preparation of cellulose films [29], fibers [30,31], and composite materials of cellulose and other polymers. [32][33][34] The cellulose-[Bmim]Cl solution is highly viscous and leads to spontaneous gelation. [35] Moreover, many researchers have exploited IL solubility to investigate acetylation, acylation and silylation [36][37][38][39] of cellulose and also bioethanol production from cellulose.…”

Cellulose is a ubiquitous natural fiber used in various industrial materials and applications. We prepared micron-sized cellulose particles by the solvent releasing method (SRM) in which cellulose-[Bmim]Cl-N,N-dimethylformamide (DMF) droplets are dispersed in hexadecane (HD) containing dissolved surfactant. The dispersion is then poured into a large amount of 1-butanol. Since 1-butanol is miscible with HD, [Bmim]Cl, and DMF but not with cellulose, the cellulose particles precipitate out. FTIR and (1)H NMR analyses confirmed that this technique precipitated cellulose and completely removed [Bmim]Cl and DMF from the cellulose-[Bmim]Cl-DMF droplets. Interestingly, the obtained cellulose particles were almost the same size as the original droplets (cellulose, 7 wt%), indicating a microporous structure of the cellulose particles with a large medium content. Although the microporous structure collapsed as the medium evaporated, it was maintained by a freeze-drying technique.
