“…All mechanical and thermal properties of the Biopolymer nanocomposites improved with addition of the bio-fillers to neat polymers [25]. The tensile strength and the Young's modulus increased and the elongation decreased with the increase of the electrochemical-mechanical liquid exfoliation (EMLE) graphene content in the composites [26]. The titanium dioxide nanoparticle enhanced the functional properties of potato starch film [27].…”

Plastic is an amazing material, and wonderful invention, it has changed the world. Plastic is used everywhere and every day across the globe. But despite its varied uses, its disposal has threatened the environment. Biodegradable plastics can meet these needs and can easily be disposed to the environment. This work focuses on the characterization and performance analysis of starch bioplastics and composite bioplastic to reduce the plastic pollution by its various uses. TGA, DSC, SEM, FTIR, and surface roughness analyses were used to characterize, the mechanical properties, thermal properties and the morphology of the starch bioplastics and composite bioplastic. Starch bioplastics were fabricated using starch vinegar and glycerol. Composite bioplastics ware fabricated using starch, vinegar, glycerol and titanium dioxide. The addition of titanium dioxide improved the tensile strength of the bioplastics from 3.55 to 3.95 MPa and decreased elongation from 88% to 62%. According to Differential Scanning Calorimetry (DSC) Test, the melting point (T m ) and Glass Transition Temperature (T g ) significantly affected by the presence of titanium dioxide (TiO 2 ). The degree of nano-composite crystallinity was formed by the strong interfacial interaction between the titanium dioxide nanoparticles and the amorphous region of the chain. The decomposition temperature of starch bioplastic was increased by mixing with titanium dioxide nanoparticles. The results gained from SEM showed that better compatible morphologies in composite bioplastic compared to starch bioplastic for its fewer voids, holes, and crack. The functional group O–H, C–H, C=O, and C–O indicate the formation of starch bioplastics and composite bioplastics has already occurred which was confirmed by FTIR spectroscopy. The result is also verified with the available results of other researchers. Therefore, composite bioplastic is a modified elevation of a starch bioplastic with a modified upgrade feature. It can be an alternative to existing conventional plastic, especially packaging applications.

In this study, cassava starch (CS) was prepared as conductive biodegradable material on zinc anode (ZnC) in zinc-air fuel cell (ZAFC) by using electrochemistry method. Successful formation of cassava on Zn anode was tested its conductivity by using four-point probe instrument and proven the enhancement of conductivity of anode after the deposition of CS. The optimization of conductivity study was further carried out in different concentrations of cassava. From conductivity analysis, it was shown the increment 30% of conductivity values from original conductivity of pure zinc. Moreover, scanning electron microscopy (SEM) and fourier-transform infrared spectroscopy (FTIR) also were conducted to evaluate the morphology and chemical chain of cassava.

Cassava starch bioplastics have been known well as an alternative plastic replacing conventional petrochemical plastics, which have difficulty degrading rapidly in the environment. Cassava peels as waste is a potential eco-friendly starch source for biodegradable plastic. This study investigated the effect of graphene as a nanofiller on the hydrophobic properties of cassava peel starch film. Bioplastic was synthesized using the melt blending method by adding graphene in various amounts, which were 3 wt%, 5 wt%, and 7 wt%. Graphene was found to be able to increase the contact angle of the films up to 93° with the addition of 5 wt%. Graphene also affects water absorption properties. These results indicate that the hydrophobic properties of cassava peel starch films could be modified by adding graphene nanofiller.
