“…It has a greatest potentiality among polysaccharides owing to its excellent ability to form a continuous matrix in addition to its abundant, renewable, and low cost . It exists in many forms depending on the origin of raw materials . Starch‐based biodegradable polymers have several advantages in biomedical applications due to their good biocompatibility, biodegradability, and nontoxic degradation products, and so on .…”

Biodegradable starch (Str) polymer was derived from potato, a plant-based natural carbohydrate polymers source, by one-pot synthesis. Hydroxyapatite (HA) was produced from goat bone by step sintering. The inexpensive starch/HA thin film composites were fabricated by customized spin coating. This study revealed that the hydrogen bond energy and distance have significant effect on glass transition temperature of the polymer. The 40 wt % HA contained starch (StrHA40) composite thin film showed excellent tensile strength (3.03 + −0.03 MPa), elongation (21.5 + −5.5%) and modulus (15.5 + −0.2 MPa) closed to human skin. The in vitro swelling and biodegradation kinetics of pristine starch and pure HA has been controlled and improved by using suitable composition. This study postulated the probable water molecule-adsorption mechanisms of pristine starch and starch/HA composite films. The StrHA40 composite showed excellent biocompatibility to the human-blood derived lymphocyte cells. Therefore, the starch/HA thin film composite-based biodegradable scaffolds developed in the present study can be an excellent potential candidate for soft tissue regeneration and/or replacement applications.

“…On the other hand, compared with synthetic polymers, starch films are highly hydrophilic with poor mechanical properties [3,4]. It has been reported that the different properties of starch-based films vary with the botanical source [10][11][12][13][14][15]. These variations are mainly due to the amylose content in the native starches (18%-30%) [16].…”

Apple starch films were obtained from apples harvested at 60, 70, 80 and 90 days after full bloom (DAFB). Mechanical properties and water vapor permeability (WVP) were evaluated. The apple starch films at 70 DAFB presented higher values in the variables of tensile strength (8.12 MPa), elastic modulus (3.10 MPa) and lower values of water vapor permeability (6.77 × 10−11 g m−1 s−1 Pa−1) than apple starch films from apples harvested at 60, 80 and 90 DAFB. Therefore, these films were chosen to continue the study incorporating ellagic acid (EA). The EA was added at three concentrations [0.02% (FILM-EA0.02%), 0.05% (FILM-EA0.05%) and 0.1% (FILM-EA0.1%) w/w] and compared with the apple starch films without EA (FILM-Control). The films were characterized by their physicochemical, optical, morphological and mechanical properties. Their thermal stability and antioxidant capacity were also evaluated. The FILM-Control and FILM-EA0.02% showed a uniform surface, while FILM-EA0.05% and FILM-EA0.1% showed a rough surface and insoluble EA particles. Compared to FILM-Control, EA modified the values of tensile strength, elasticity modulus and elongation at break. The antioxidant capacity increased as EA concentration did. EA incorporation allowed obtaining films with higher antioxidant capacity, capable of blocking UV light with better mechanical properties than film without EA.

“…Depending on origin of starch, give rise to a variety of films. The films based on maize , banana (Sartori et al, 2016), cassava (Bourtoom et al, 2008, Souza et al, 2013, potato starch (Talja et al, 2007), have been already presented in the literature. The most widely used technique for the laboratorial production of starch-based films is casting method (Vicentini et al, 2002;Mali et al, 2005a;Müller et al, 2008).…”

Due ecological reasons there is a considerable interest in biodegradable films made from renewable and natural polymers, such as starch. Starch films are not meant to totally replace conventional packaging polymer films, but they might be a competition in several application, where traditional packaging cannot function. Moreover, starch as a raw material exhibit many benefits, such as relatively low price, abundant, biodegradable, and edible. Films prepared from starches are isotropic, odourless, tasteless, colourless, non-toxic and biodegradable. Finally, they are nutritious and safe, so they are used in the marketing of food. Unfortunately, the starch films present poor tensile properties and sensitivity to moisture content. In order to modify starch films properties the addition of various plasticizers is used. Commonly as a plasticizer water and glycerine is used. In this work, we use glycerol derivatives as a modern plasticizers for starch films obtained from potato starch by the tape casting technique, which allows to obtained films with constant thickness and 20 cm length. The influence of the ratio of various plasticizers: glycerol, pentaerythiolethoxylate, glycerol ethoxylate and Poligliceryn-3 on the mechanical properties and surface free energy was investigated. The plasticizers selected by us are characterized by a large number of functional hydroxyl groups. The starch films with the mixture of plasticisers reveal better usable properties and higher mechanical properties than with only one plasticizer. However, glycerol derivatives they cannot be used without the addition of glycerol. Furthermore, surface free energy was determinate by Owens-Wendt and van Oss-Chaudhury-Good method. The values of SFE are in the range 50-60 mJ/m 2 and higher than values of typical plastic films, which are used in packaging industry. Obtained starch films are characterized by quite high polar component of SFE, with may be related with the influence of hydroxyl groups. Our results support the use of glycerol derivatives as modern plasticizers for biodegradable films and may open up new possibilities for applications of these compounds.
