“…It is believed derivatives of cellulose are good candidates for making composites because they are naturally obtainable materials and have good physical features. Cellulose can be used to make composites by mixing with appropriate adhesives and other polymers, producing novel characteristic and meeting additional requirements [13]. Because of these characteristics, CA has been widely studied for a wide variety of potential applications in the form of electrospun nanofiber mats.…”

“…It is unsuitable for common uses because of its high melting temperatures, high viscosities and relatively low decomposition temperatures [13]. Ketoprofen (KET) is selected as a model drug, it is a non-steroidal antiinflammatory drug (NSAID) and is classified among the most effective inhibitors of the cyclooxygenase pathway of the arachidonic acid cascade; it also inhibits lipooxygenase, widely applied to alleviate pain and inflammation associated with tissue injury [22].…”

Sustained release cellulose acetate (CA) and ethyl cellulose (EC) polymer blend nanofibers loaded with ketoprofen (KET) were successfully prepared by electrospinning. Successful fiber formation has been investigated by using two different binary solvent systems, i.e., acetic acid + distilled water (2:1 v/v) and acetone + N,N-DMAc + ethanol (2:1:1 v/v). Scanning electron microscopy (SEM) images showed that morphological features gradually change as the ratio of both polymers change. Nanofiber diameter also decreases as the CA content is increased in the polymer blend solution from 77.25±27 to 72.39±30 nm. Drug release profiles were evaluated by in-vitro drug release experiments. Drug release follows a pseudo-Fickian behavior of diffusion and shows a sustained release mechanism. Nanofibers containing more CA show greater controlled release capacity as compared to EC. X-ray diffraction (XRD) patterns of CA and EC polymer blend nanocomposites show that crystalline ketoprofen has changed into an amorphous state. Fourier transform Infrared (FTIR) analysis indicates hydrogen bonding occurs between the drug and the polymer, accounting for molecular integration of the two components. The thermal stability of the prepared polymer blend was also studied using thermo-gravimetric analysis (TGA). A polymer blend sustained release drug delivery system prepared by electrospinning make it possible to fabricate other novel drug releasing systems.

“…The area of biodegradable material application is continuously extending thanks to their improving properties which in many cases resemble petrochemical polymers. In spite of many studies concerning the usage of biodegradable polymers, such as poly(lactic acid) (PLA) [2][3][4][5][6][7][8][9][10], poly(butylene adipate-co-terephthalate (PBAT) [11][12][13], polypropylene carbonate (PPC) [14][15][16], and starch [17][18][19][20], their commercial application is still not very common. Packaging industry appears as a branch which due to relatively low expectations towards mechanical properties allows for wide application of fully biodegradable polymers on a bigger scale [5].…”

expansion of petroleum-based polymers. Despite trials of the reducing polymeric waste and strong restrictions concerning storage and product end-life cycle performance, the amount of the non-degradable polymer gradually has become ballast for the environment. Therefore, the endeavor of introducing biodegradable polymers in industrial-scale production gained ground among scientists [1]. The area of biodegradable material application is continuously extending thanks to their improving properties which in many cases resemble petrochemical polymers. In spite of many studies concerning the usage of biodegradable polymers, such as poly(lactic acid) (PLA) [2][3][4][5][6][7][8][9][10], poly(butylene adipate-co-terephthalate (PBAT) [11][12][13], polypropylene carbonate (PPC) [14][15][16], and starch [17][18][19][20], their commercial application is still not very common. Packaging industry appears as a branch which due to relatively low expectations towards mechanical properties allows for wide application of fully biodegradable polymers on a bigger scale [5]. The low thermo-mechanical stability of green composites, next to relatively high price, became their biggest disadvantage in comparison to petroleum-based non-biodegradable polymers [5,13]. Therefore, it is well founded to use recycled thermoplastic biodegradable polymers as a matrix for composites filled with organic and inorganic fillers [7,11].Except for the application of the specially prepared fiberlike natural fillers (e.g., bamboo, kenaf, jute and flax), great attention is placed on incorporation of agricultural waste materials into polymeric matrix [2,[21][22][23][24][25]. Extensive studies showed that presence of the natural fillers in biodegradable polymers may strongly accelerate biodegradation process thanks to faster hydrolysis followed by oxidation of both biopolymer, as well as the filler. Moreover, presence of natural filler increases water absorption, which highly influences biodegradation process of the composites, in comparison to neat polymer. In case of natural composites Abstract The aim of this study was to determine thermal and mechanical properties and applicability of ground chestnut shell waste as a filler for poly(lactic acid) composites. The used amount of filler was ranging from 2.5 to 30 wt%. Spectroscopic analysis of composites and its ingredients was conducted by means of FT-IR method. The mechanical and thermal properties of the composites were determined in the course of static tensile test, Dynstat impact strength test, DMTA analysis, and DSC method. The fractured surface morphology of biocomposites was evaluated by SEM analysis. Incorporation of the filler influenced the overall mechanical properties of the composites characterized by high stiffness and lowered impact resistance. Fabricated composites with different amounts of non-reactive natural waste filler exhibited acceptable mechanical and thermal properties. Therefore, these composites can be used as eco-friendly, biodegradable materials for low-demanding applications.

“…polymerizing with additional backbone components [9][10][11], cross-linking [12][13], end-capping [14][15][16] and hydrogen-bonding [17][18][19][20][21][22]. In these methods, performance improvement of polymer blends or composites via the hydrogen-bonding interaction is a rather effective method.…”

Impact strength, initial decomposition temperature and glass transition temperature of pure PPC and PPC/SF-PA66 composites Via hydrogen-bonding interaction, poly(propylene carbonate) (PPC) was firstly reinforced by polyamide 66 short fiber (SF-PA66). The tensile and impact strength, thermal stability of composites increased when the SF-PA66 content ranges from 5% to Downloaded by [UNSW Library] at 03:31 19 August 2015 2 20%, then decreased at 30%. The increment in impact strength, decomposition temperature of 5% mass loss and glass transition temperature of PPC/20%PA66 is 315.81%, 32.2 °C and 3.8°C, respectively. FTIR and 1 H NMR results illuminate that the introduction of hydrogen bonding interaction between PPC and SF-PA66. Moreover, the network structure formed when SF-PA66 content is higher than 20 wt%. It is confirmed by rheological responding curves that a plateau at low angle frequency occurs. In addition, a significant aggregation of SF-PA66 occurs when its content is 30 wt%, which causes the decrease in mechanical and thermal properties of PPC/SF-PA66 composites.
