“…The spherical, dark, aggregated CuO is clearly visible, and 1% CuO is evenly distributed uniformly on the surface. This is owing to the surfactant CTAB's assistance in the binding between BC and CuO, as described in earlier investigations [16]. The graphene was filled porosity by adding graphene to BC/CuO nanocomposite tissue.…”

Bacterial cellulose (BC) is a widespread, low-cost biopolymer that has generally been produced from plants and biomass waste. A method for improving the range of applications for bacterial cellulose is adding graphene material. It has an outstanding feature that can increase the performance of nanocomposite materials. The research aims to observe the effect of graphene on the surface morphology, crystallinity, chemical bonding, and tensile strength of BC/CuO nanocomposite. For this study's synthesis, BC was synthesized by fermenting pineapple peel extract for 10 to 14 days. The produced BC was crushed, homogenized with a nano homogenizer machine, and filtered. Filtered BC, CuO, and graphene were added to obtain a solution, and the mixture was first stirred magnetically, followed by an ultrasonic homogenizer, and finally dried using a freeze-dry method to make a porous nanocomposite. According to SEM analysis, the addition of CuO and graphene can fill porosity nanocomposite. By XRD analysis, the addition of graphene reduces the crystallinity of BC/CuO. The FTIR data showed that adding graphene reduces hydrogen bonding and makes some Cu-O-C bonding. The tensile test has demonstrated that the tensile strength of BC-based nanocomposite with graphene reinforcement tends to decrease.

“…This is caused by the presence of chitosan during the composite synthesis process 21 . Graphite is characterized by flat flakes with sharp corners, while PVA appears evenly dispersed in the composite 22,23 . The interactions between G and PVA fillers in the BC matrix are attributed to hydrophobic and electrostatic interactions with CTAB as a surfactant.…”

Bacterial cellulose (BC) is a biodegradable natural polymer with high mechanical strength and non-toxicity. This biopolymer is widely used as a candidate in biomedical fields, such as drug delivery, wound healing, and filtration systems. However, BC lacks antibacterial activity which limits its use in biomedical applications. So, modification of BC-based composite is required. This study aims to examine the effects of modifying BC-based composites with fillers such as graphite (G) and polyvinyl alcohol (PVA) on the release of tetracycline hydrochloride (TCH) drugs. Adding fillers to BC can alter its physical and mechanical properties, reducing its porosity and swelling rate in acidic and alkaline mediums. The drug release of TCH from modified BC-based composites follows the Korsmeyer-Peppas and Hixson-Crowell kinetics models. Adding filler and TCH antibiotic to the composite enhances its antibacterial activity against Staphylococcus aureus with a significant inhibition zone. The results of the inhibition zone show that composites have the potential to be applied in biomedical fields, especially in transdermal patches.

“…Bacterial Cellulose (BC) is widely known as a natural polymer, one of them is a membrane [5]. The membrane from cellulose has character with a thin layer that acts as a barrier to a specific species, BC membrane can separate substances of different sizes and limit the transport of different species based on their physical and chemical properties.…”

Indonesian pineapple production can reach 200 tons per day; however, pineapples generate a significant amount of waste. Pineapple peel waste can be used to make membranes. Composite membranes containing TiO2 have dense properties, low porosity, and increase the mechanical strength of the cellulose sheet. This research uses various ultrasonic homogenizers to homogenize the distribution of nanocellulose and TiO2 (50% and 100% power with 30, 60, and 90 minutes). The casting method is used to shape the membrane. The SEM test shows that the higher the power used and the longer the sonication time, the less agglomeration of about 1.63%/ cm2 and a thickness of 16.56 µm. Identification of X-ray diffraction (XRD) results shows that sonication treatment for too long causes the peak at an angle of 25o to disappear. The analysis revealed no new peaks in the diagram pictures that were found using Fourier Transform Infrared Spectroscopy (FTIR) to analyze the functional groups, but it is known that changes occur in the O-H bonds of cellulose and C=C. The 50% sample with a power of 60 minutes had the lowest roughness value of 1.008 µm. Furthermore, as the power and time on the sample are increased, the roughness increases.
