In this regard, the effect of mentioned additives on the mechanical properties, oxygen permeability, water absorption rate and anti-microbial properties of recycled PET/ABS blend were examined. The results revealed that the addition of ABS to PET can lead to an increase in tensile strength, while it can lead to a decrease in the elongation at break and Young's modulus. Moreover, the addition of Oak shell and potassium sorbate to the PET/ABS mixture can enhance the antimicrobial properties. However, these additives can lead to a significant increase in the water absorption and oxygen permeability within the PET/ABS mixture. On the other hand, reinforcement of PET/ABS with egg shell nanoparticles not only improves the mechanical properties of PET/ABS but also can lead to a decrease in the water absorption and oxygen permeability compared with neat PET/ABS. The main aim of this study is to develop anti-bacterial and degradable plastic structures based on recycled PET/ABS to find a solution for recycling plastic based scraps or improving their natural degradability.","PeriodicalId":20353,"journal":{"name":"Polymers from Renewable Resources","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/204124791700800403","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46460313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, the use of bioactive compounds has been directly associated with the promotion of health aspects; the ingestion of bioactive compounds is related with minimizing risks of some diseases such as hypertension, diabetes, and coronary heart diseases. Therefore, the present study carried out a review of the current scenario in the film's production with natural antioxidants addition. The prebiotics and probiotics compound addition in films properties produced were also discussed in this work. Additionally, the film biodegradation properties should also be taken into account for their right disposal in the environment. Some factors that can to affect the biodegradation process are the nature of the polymer, the interactions among the blend components, its crystallinity, and the environmental conditions (light, temperature, O2 concentrations; and humidity). Therefore, the evaluation of relationships between structure and the polymers biodegradability is the extreme importance.","PeriodicalId":20353,"journal":{"name":"Polymers from Renewable Resources","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/204124791700800402","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46971858","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work aimed to produce nanosized filler for biobased materials from renewable resource by an efficient production. Banana and tapioca starch nanocrystals (SNCs) were prepared from mild acid hydrolysis method. The effects of acid type, acid concentration, reaction time, and temperature on percent yield and degree of crystallinity were investigated in order to find the suitable condition for SNCs preparation. The chemical structure, degree of crystallinity, and morphology of the obtained SNCs were examined by Fourier transform infrared spectroscopy (FT-IR), X-ray powder diffraction (XRD), and transmission electron microscopy (TEM), respectively. Thermal properties were characterized by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). The results revealed that the suitable conditions for preparing SNCs were by using 3.5 M H2SO4 at 40°C for 7 hrs or 10 hrs depending on starch type, which leading to high degree of crystallinity as 47.13% and 60.06% for banana and tapioca SNCs, respectively. The particle size of both SNCs was less than 200 nm, approximately 30–70 nm. The banana SNC displayed parallelepiped nanoplatelets with C-type crystallinity, while the tapioca SNC showed spherical nanoplatelets with A-type crystallinity. The degradation temperature of banana and tapioca SNCs occurred in ranging between 280 and 310°C, which was lower than their native starches due to the disintegration of the SNC molecular chain during acid hydrolysis reaction. Nevertheless, melting enthalpy (ΔH) of SNC fillers enhanced after hydrolysis indicating that there was an increment of degree of crystallinity owing to the chain rearrangement of starch molecules.","PeriodicalId":20353,"journal":{"name":"Polymers from Renewable Resources","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/204124791700800302","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48870831","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, the mucilage of the fruit of Cordia lueta has been extracted and characterised in order to explore its potential applications. Thermogravimetric tests were used to measure the water content of this natural mucilage. Differential scanning calorimetry allowed assessing thermal transitions and thermal degradation of the samples. Steady flow rheometry was used to measure the viscosity of the samples as a function of the shear rate. Dynamic oscillatory rheometry was used to study the variation of the storage and loss modulus of the mucilage as function of the oscillatory frequency and stress. The results showed that this mucilage is a polysaccharide network that behaves as a pseudoplastic fluid. Its storage modulus is not completely independent from the oscillation frequency. In addition, the stress sweeps showed that C. lutea mucilage has a reversible stress softening behaviour. The findings reported in the present work suggest that this mucilage can be used as a rheology modifier for commercial foods and biomedical materials.","PeriodicalId":20353,"journal":{"name":"Polymers from Renewable Resources","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/204124791700800301","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41642000","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
