“…According to Antoniou et al, the arrangement of nanoemulsions can clog the films pores causing more tortuous pathways for the diffusion of the water vapor molecules. Reduction in WVP found by Ilyas et al while studying sugar palm nanocrystalline cellulose reinforced sugar palm starch composite was also attributed to the tortuous path caused by the presence of nanostructures. Despite increasing the water vapor barrier with the addition of carnauba wax nanoemulsions and neem oil nanoemulsions, only the Noil30 formulation differed statistically from the pure pectin sample, showing efficiency in increasing the water vapor barrier.…”

The search for biodegradable materials motivated the development of new materials for the food industry. Biomaterials (pectin, starch, and chitosan) are considered promising biodegradable polymers for developing or improving materials. This study aimed to develop biodegradable bionanocomposite films with neem oil and carnauba wax nanoemulsion using pectin (high methyl esterification) polymer matrix; and to evaluate the nanoemulsions effects on the water vapor permeability (WVP), mechanical, thermal, and biodegradability properties of the films. Nanoemulsions were characterized by the polydispersity index and mean particle diameter. These results showed an average diameter of 59 to 69 nm. The pectin and 30% of neem oil nanoemulsions showed a 27% reduction in WVP. In addition, the mechanical property was optimized. Young module showed a 66% to 75% reduction for pectin and 30% of carnauba wax film and pectin and 30% of neem oil film. In the biodegradability analysis was presented a very fast degradation in soil. In addition, there was no macroresidue formation in soil with neem oil films during the biodegradation process. This result showed a weight loss after 45 days of testing. Developed bionanocompositie materials have great potential for application in emerging packagings (edible films and coatings) for the food industry and agribusiness area (food and seeds).

“…Besides, the high crystallization of SPNFCs in accordance with an increment of SPNFCs concentration in the nanocomposite might also be ascribed to the decrease of the diffusion coefficient and water uptake at the equilibrium of the biofilms. [57,58] As a result, the increase in the concentrations of SPNFCs nanofiller had resulted in low water uptake. It could be concluded that the SPNFCs reinforced biofilms possessed higher water resistance compared to control SPS.…”

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.

“…Biodegradability test was conducted to measure the weight loss of control biopolymer films and nanocomposites films after they were buried in a soil for a certain time. The biopolymer films with a size of 3 × 1 cm were buried into the soil with a depth of 10 cm beneath the soil surface [1,6,26,27]. After 24, 48, 72, 168, 216, and 264 h, the samples were dug out, washed with distilled water and weighed.…”

“…Among various types of renewable polymers, starch is one of the most widely used and favorable materials for biodegradable plastic due to its low cost and high availability [3][4][5]. In the last decade, the thermoplastic starch, or plastic starch (PS), has gained attention and offered an attractive alternative to petroleum-based polymers when long-term biodegradation is unnecessary and rapid degradation is needed [6,7]. However, plastic starch biopolymer still exhibits some drawbacks, such as poor mechanical properties and high hydrophilic nature.…”

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. The major factors contributing to the increase of interest include the rise in petroleum prices and the inevitable environmental pollution contrib-1)
