“…This thermal responsiveness holds significant implications for designing and optimizing materials with tailored properties. For instance, using the grafted semi or fully-fluorinated polymer units brings about an increment in thermal stability and decrement in the flammability of the polymers [15][16][17][18]. As well as thermal behavior, it is important which gaseous substances are released when the polymers are exposed to the increasing temperature.…”

In this study, the thermal degradation behavior of both poly(3,3,4,4,5,5,6,6,7,7,8,8,8-dodecafluoro-5-methyloctyl-4-(acryloyloxy) benzoate), poly(ABCF13) and its graft copolymers onto high-density polyethylene (HDPE) was investigated in detail. The homopolymers and grafted copolymers were synthesized using the bulk-melt polymerization method in the presence of benzoyl peroxide; 10% and 40% of ABCF13 were used in the graft copolymers. The combined analytical technique, Thermo Gravimetric Analysis coupled with Fourier Transform Infrared Spectroscopy (TGA/FTIR), was utilized to understand the obtained products' thermal behavior and formed decomposition chemicals. The thermal tests were carried out in both air and N2 atmospheres. The experimental results showed that the first weight loss of poly(ABCF13) in air and N2 atmospheres started at about 226°C (1.00%), and the primary and early decomposition product was determined as CO2. The weight loss pattern in graft copolymers at lower concentrations closely resembled that of the homopolymer. However, at higher concentrations, the resulting products exhibited a distinct decomposition mechanism characterized by a gradual decrease in trend. This segmented behavior may indicate the coexistence of the homopolymer and grafted copolymers within the matrix. Moreover, the findings showed that the semi-fluorinated grafted unit had a substantial retardation effect on the polymer.

“…12 Here, it was to be emphasized that the existence of high compatibility and good adhesion between components led the formed composites to exhibit better mechanical performance compared to both partly miscible and immiscible polymer matrices. 13,14 In other words, the formation of relatively stronger and effective intermolecular attraction forces (Van der Waals forces) between the component polymer chains in the matrix provides both the additional endurance and relatively larger withstanding capability against the deformation to the polymeric materials, 15 which results in the reinforcement of the polymer composites. Furthermore, the various chemical methods like silane and alkaline treatments, acetylation, and bleaching were also used in order to get rid of this compatibility problem coming out in the polymer matrices.…”

This present study centers sensitively on the determination of the effect of natural turkey feather fibers (TFFs) loading on fundamental features (thermal, mechanical, water-uptake, and micro-structural) of thermoplastic polyurethane (TPU). The composites with different TFFs contents (3, 6, 9, and 12 wt.%) were fabricated by the melt blending method using the twin screw extruder and micro-injection molder. The samples were characterized by means of differential scanning calorimeter (DSC), universal mechanical (tensile and hardness) tester, water-uptake, and scanning electron microscope (SEM) techniques. The thermal analysis depicted that the melting temperatures of the soft and hard segments as well as the crystallinity degree of TPU increased consistently with the increase of TFFs loading level thanks to the formation of better close-packed TPU chains in the matrices. As for the mechanical test results, when compared neat TPU, the tensile strengths were reinforced by 26.8% and 19.7%, and the modulus increased by 6.6% and 45.1% for the composite samples including 3% and 6% of TFFs, respectively. However, drastic diminishment were observed at further contents. Additionally, TFFs loadings brought about gradual increase in the water-uptake capacities of the composites due to the increasing of the number of voids and omnipresent flaws in TPU matrices. The taken SEM images also revealed that, at low contents, there existed the enrichment of interfacial adhesion between TFFs and TPU matrix, whereas the morphological appearance of the composites get worse at high contents accompanied by the formation of micro-structural defects.
