“…Such a strategy does retain the intrinsic properties of carbon nanotubes, but, unfortunately, interfacial stress transfer might not be so effective in the treatment for the nanocomposites. It is usually difficult for this modification strategy to improve the interfacial properties efficiently [224,225], and considerable improvements remain to be exploited.…”

The current state of characterization techniques for the interface in carbon nanotube-reinforced polymer nanocomposites is reviewed. Different types of interfaces that exist within the nanocomposites are summarized, and current efforts focused on understanding the interfacial properties and interactions are reviewed. The emerging trends in characterization techniques and methodologies for the interface are presented, and their strengths and limitations are summarized. The intrinsic mechanism of the interactions at the interface between the carbon nanotubes and the polymer matrix is discussed. Special attention is given to research efforts focused on chemical functionalization of carbon nanotubes. The benefits and disadvantages associated with covalent and noncovalent functionalization methods are evaluated, respectively. Various techniques used to characterize the properties of the interface are extensively reviewed. How the mechanical and thermal properties of the nanocomposites depend on the physical and chemical nature of the interface is also discussed. Better understanding and design of the interface at the atomic level could become the forefront of research in the polymer community. Potential problems going to be solved are finally highlighted.

“…Most prominently, polyester nanocomposites are filled with carbon nanotubes and graphene nanofillers. [52][53][54] EMI shielding efficiency of polyester/nanocomposite needs to be enhanced to 20 dB to obtain technologically important materials. Preliminary studies indicated that using modified carbon nanotubes 98,99 and functional graphene nanosheets [100][101][102] may result in improved shielding efficiency for these materials.…”

Polyester is a versatile commercially significant polymer (thermoplastic/thermoset) well-known for its biodegradability and excellent thermal, mechanical, and chemical properties. Synthetic aromatic polyester resins usually have better moisture resistance, nonflammability, liquid crystal, strength, thermal, and environmental features compared with natural/aliphatic polyesters. Nanofillers can reinforce these important polymers to further enhance the final nanocomposite structural and physical characteristics. This review presents research devoted to polyester nanocomposites with essential nanofillers such as; nanodiamond, fullerene, carbon nanotube, graphene, and graphene oxide. High-performance polyester/nanocomposites have been developed based on modified polyester design, nanofiller functionality, and optimized interaction between matrix and nanofiller. This article also presents state-of-the-art technological development in the field of polyester/nanocomposites predominantly in supercapacitors, fuel cells, shape memory materials, electromagnetic shielding materials, textiles, and biomedical appliances. Furthermore, future scenarios in scientific development of these nanocomposites are discussed.

“…PCA is aliphatic polyester that has electron deficient alkyne units which can be functionalized with a variety of reactive groups such as azides, amines, and dienes using common organic reactions compared to others. [22][23][24][25] The importance of fabrication of reactive, clickable and biodegradable polymeric fibers like PCA for several applications has been recently studied and reviewed in the literature. [26][27][28][29] In the light of the all of aforementioned information, herein, PCA fibers were produced from their solutions in chloroform by means of basic electrospinning system under ambient conditions for the first time.…”

production of environmentally friendly and biodegradable materials in academia and industry. [1] Three main classes of biodegradable polymers can be categorized in the literature: i) natural polymers such as polysaccharides, cellulose, starch and chitin or chitosan ii) synthetic polymers achieved after polymerization reactions such as polylactic acid (PLA) and poly(εcaprolactone) (PCL) or iii) blended form of both. [2] From the viewpoint of material development, thermoplastic linear aliphatic polyesters such as particularly PLAs, PCLs, polyglycolides (PGAs), poly(β-hydroxybutyrates) (PHBs) have a leading position and popularity in various areas ranging from biomedical to packaging industries due to their compostability, biocompatibility, degradability, eco-friendly and easy processability features. [3,4] Besides these attractive attributes, their good mechanical and thermal properties meet greatly the requirements of environmental, agricultural and surgical concerns. In addition, various functional groups on their hydrocarbon main chains can be easily modified for use in common chemical reactions and allow the material to be easily adapted to different processing methods. [5-9] Therefore, it is obvious that the production of innovative aliphatic polyesters with various functional groups and properties is of great importance for use in a wide variety of application areas. A variety of effective strategies have been used to generate the continuous fiber of natural, synthetic or blend polymers and inorganic materials origin including centrifugal or electro spinning, mechanical drawing, melt blowing, self-assembly, phase separation, template synthesis and freeze-drying for targeted applications. [10-13] However, unmanageable procedures, unsuitability for some polymers, non-adjustable fiber diameter and direction are among the disadvantages of most of these techniques. As a straightforward fiber fabrication method, electrospinning is adaptable to a variety of materials, and versatile technique for producing fibers with well-controlled surface topography, morphology and size distribution within a fiber diameter down to the nanometer by means of the electrostatic forces. [14] In this method, there are a number of process variables that need to be carefully optimized for the production This study is conducted to evaluate the biodegradation and thermal features of poly(1,4-cyclohexanedimethylene acetylene dicarboxylate) (PCA) based films and fibers. The PCA is characterized by Fourier transform infrared (FT-IR) and proton nuclear magnetic resonance (1 H-NMR) spectroscopies and gel permeation chromatography (GPC). The beadless fibers of PCA are achieved by electrospinning from its solution under ambient conditions for the first time. The effects of applied voltage and tip-to-collector distance (TCD) on the various properties such as morphology, wettability, thermal, and biodegradability behaviors of fibers are investigated by comparing the non-electrospun PCA. Morphologies and average frequency distributions of the electro...
