“…The significant decrease in the Tr was profoundly affected by the introduction of nanocellulose on the interface structure. This phenomenon may be attributed to (a) the presence of SPNFCs nanofiller, (b) high surface area of SPNFCs at 14.01 m 2 /g, [22] (c) strong interaction between the SPNFCs nanofiller and the SPS starch matrix, and (d) homogeneously random distribution of SPNFCs in the matrix. Wang et al [45] also stated that increasing the cotton linter nanocellulose content within soy protein thermoplastic resulted in a decreased optical transmittance (Tr) of nanocomposite films, as congruently described by Pelissari et al [32] that banana nanocellulose reinforced with banana starch behaved in the same way.…”

“…Some of their fascinating performances are large surface area (100 m 2 /g) which successively improve the surface to volume ratio of 100 as well as their low density, better crystallinity, enhanced mechanical performance, production of stronger porous mesh, and reduced weight and density. [22] Moreover, these nanofibers were described to exhibit high modulus (150 GPa) and high strength (10 GPa), as they are very suitable for the reinforcement of composite material. In addition, the material also has low production cost due to the abundance of resources, consume less energy during manufacturing process, and easy to recycle via combustion.…”

Sugar palm fiber (SPF) is an agro‐waste plant that can be used as potential source of biomass for various biomaterial applications. In this study, sugar palm nanofibrillated cellulose (SPNFC) that was isolated from SPF was used as a nanofiller to reinforce sugar palm starch (SPS) to produce bionanocomposites. To attain SPNFCs, SPF was undergo strong acid and alkaline treatments. Later, the SPNFCs were prepared from SPFs via high pressurized homogenization process. The reinforcement of SPNFCs (0‐1.0 wt%) and SPS is done by using solution casting methods. The films were characterized in terms of physical properties such as light transmittance, moisture content, water solubility, and water absorption. The resulting nanocomposites permitted better water resistance, low moisture absorption, and low light transmittance as compared to control SPS film. Adding 1 wt% SPNFCs loading significantly improved the water absorption and water solubility of the composite film by 24.13% and 18.60%, respectively, compared with the control SPS film. This was attributed to the high compatibility between the SPNFCs and SPS matrixes, which composed of the multi‐hydroxyl polymer having three hydroxyl groups per monomer. Thus, this study is to show the potential of SPS/SPNFCs nanocomposite films in packaging industries.

“…HPH is known as one of the eco-friendly methods due to its efficiency and simplicity and does not require any organic solvents during the process. HPH process involves passing the cellulose slurry through a very small nozzle at high pressure energy to break the cellulose slurry to the smallest possible size of the fibers from micro to nanoscale [16]. Recently, the application of NFCs as a load-bearing constituent in the development of novel and low-cost biodegradable materials has been raised [17][18][19][20].…”

This paper aims to study the degradation rate of sugar palm nanofibrillated cellulose (SPNFCs) and sugar palm starch (SPS). SPNFCs were isolated from sugar palm fiber, while SPS is extracted from sugar palm trunk. The SPNFCs were reinforced with SPS biopolymer as biodegradable reinforcement materials of different diameter/length based on the number of passes of high pressurize homogenization process (5, 10 and 15 passes represented by SPS/SPNFCs-5, SPS/SPNFCs-10, and SPS/SPNFCs-15). These SPNFCs were incorporated into SPS plasticized with glycerol and sorbitol via solution casting method. Soil burial experiment performed on SPS and SPS/SPNFCs bionanocomposites showed that SPS was degraded more rapidly by losing 85.76% of its mass in 9 days compared to 69.89% by SPS/SPNFCs-15 bionanocomposite. The high compatibility between SPNFCs nanofiber and SPS biopolymer matrices can be observed through field emission scanning electron microscopy (FE-SEM). Degradacja i właściwości fizyczne bionanokompozytów skrobi palmy cukrowej wzmocnionej nanowłóknami celulozowymi tej palmyStreszczenie: Zbadano szybkość degradacji nanowłóknistej celulozy wyizolowanej z palmy cukrowej (Arenga pinnata) (SPNFCs) oraz skrobi wydzielonej przez ekstrakcję z rdzenia pnia tej palmy (SPS). SPNFCs uzyskiwano z włókien palmy cukrowej, poddawanych homogenizacji pod wysokim ciśnieniem w 5, 10 lub 15 cyklach, otrzymując nanowłókna celulozy o różnej długości i średnicy. SPNFCs wprowadzano do SPS uplastycznionego mieszaniną (1 : 1) glicerolu i sorbitolu. Metodą odlewania z roztworu wytwarzano błony nanokompozytowe SPS/SPNFCs-5, SPS/SPNFCs-10 i SPS/SPNFCs-15. Test glebowy procesu biodegradacji wykazał, że SPS ulegało szybszej degradacji, tracąc 85,76% swojej masy w ciągu 9 dni, w porównaniu z ubytkiem masy 69,89% w wypadku bionanokompozytu SPS/SPNFCs-15. Na podstawie analizy metodą skaningowej mikroskopii elektronowej z emisją polową (FE-SEM) stwierdzono dużą kompatybilność między nanowłóknami SPNFCs i biopolimerową osnową SPS.Słowa kluczowe: palma cukrowa, homogenizacja wysokociśnieniowa, nanowłóknista celuloza, nanokompozyty, degradacja w glebie.Nowadays, total biodegradable green composite or biocomposite, which are made up of natural matrices and natural fibers, have attracted many researchers for the advantages they offer.

“…29 Moreover, nanofibrillated cellulose of sugar palm was obtained by several chemical pretreatment steps, such as pulping, bleaching, mercerization, finally followed by high-pressurized homogenization. 30 In contrast to previous works, this study aimed to obtain nanocellulose from sugar palm fiber by simple acid hydrolysis, directly combined with high-pressure homogenization. The structural and physical-chemical properties of the nanocellulose were evaluated by transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and CP/MAS 13 C-NMR spectroscopy.…”

Nanocellulose was isolated from sugar palm (Arenga pinnata) fiber, using a combined treatment of acid hydrolysis and high-pressure homogenization. Sugar palm fibers (SPF) were initially pretreated with an acid solution to dissolve cellulose. Then, the aqueous solution of cellulose fibers (0.2% w/v) was passed through a high-pressure homogenizer at 20 MPa during 15 cycles to provide sugar palm (SP) nanocellulose. The morphology and structure of SP nanocellulose was characterized using transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and CP/MAS 13 C-NMR spectroscopy. The results showed that the acid hydrolysis of SP fiber, combined with high-pressure homogenization, produced nanocellulose with increased crystallinity, but it did not change the chemical structure of cellulose.
