In this study, a new strategy is provided to enhance mechanical, barrier, and optical properties by the synergetic effect of manipulating the amorphous chain entanglement network and constructing the “nano- walls” of highly aligned calcium sulfate whisker (CSW), zinc phenylphosphonate (PPZn), and well-defined crystals via biaxial stretching. PPZn is verified as a nucleator to accelerate the crystallization rate and induce α-form crystals. CSW is regarded as a supporting skeleton to strengthen the entanglement density of the chain network. The extensional stress, which is induced by biaxial stretching, regulates the amorphous chain entanglement network and facilitates the chain orientation. As a result, the synergetic structure displays an outstanding capacity for improving the mechanical, barrier, and optical properties of PLA. Compared to the PLA film, the biaxially stretched PLA/PPZn/CSW films exhibit high strength, excellent ductility, and superior crystallinity, which are significantly increased by up to 53.2%, 381.3%, and 748.9%, respectively. And their gas and water vapor barrier properties remarkably increased by 65.39% and 73.11%, respectively. The optical property with a haze value of 52.4% and good transmittance of 97.4% is also obtained via the synergetic effect. With the excellent comprehensive properties of PLA films, this new strategy explores a new field in environmentally friendly packaging materials and is relevant to future work.","PeriodicalId":11806,"journal":{"name":"e-Polymers","volume":null,"pages":null},"PeriodicalIF":3.7,"publicationDate":"2024-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141190471","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Research on fatigue damage characteristics and fatigue life prediction of fiber-reinforced composites can help to solve such problems. Carbon fiber-reinforced epoxy resin matrix composite laminates are taken as the object of this study. By analyzing the fatigue failure process and the fatigue failure micromorphology of the specimen, the primary damage forms and fatigue damage characteristics of its fatigue failure were obtained. The fatigue failure process of fiber-reinforced composites was simulated using finite element analysis software ABAQUS and its UMAT subroutine function. The tensile–tensile fatigue damage characteristics and failure mechanism of fiber-reinforced composites were studied, and the fatigue life of the composites was predicted. The feasibility of this life prediction method was verified by comparing it with experimentally obtained damage processes and fatigue lives. This intuitive and reliable life prediction method has good research potential for predicting the fatigue limit of fiber-reinforced composites.","PeriodicalId":11806,"journal":{"name":"e-Polymers","volume":null,"pages":null},"PeriodicalIF":3.7,"publicationDate":"2024-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141190482","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fiber spinning from starch biopolymer and its blends was widely attempted using electro-spinning; however, it is less attempted using melt spinning which is an industrially feasible method. In this study, native tapioca starch is converted into thermoplastic starch (TPS), blended with polylactic acid (PLA), and is attempted for melt spinnability in its neat and blended form TPS/PLA (70/30) with the intention of checking the possibility of melt spinning. The results from characterization of the prepared biopolymers show that thermal analysis of neat TPS does not reveal clear thermal transitions, glass transition (<jats:italic>T</jats:italic> <jats:sub>g</jats:sub>), and melting (<jats:italic>T</jats:italic> <jats:sub>m</jats:sub>), in the second heating curve, rather it influenced crystallization behavior of PLA as seen from differential scanning calorimetry result and degradation temperature (<jats:italic>T</jats:italic> <jats:sub>d</jats:sub>) was found to be in the range of 296–352°C from thermogravimetric analysis showing that addition of PLA improved thermal stability of TPS. Morphology analysis with AFM images revealed the presence of granular starch in neat TPS and phase separation in TPS/PLA blends with finer phase distribution in the presence of additives. Fourier transform infrared spectroscopy result shows the interaction between starch, glycerol, and PLA showing the effect of thermoplasticization of starch which brings rupture or weakening of the strong glycosidic bonds in between starch molecules and interaction between TPS and PLA as it can be seen from peak shift and peak intensity. The melt spinning trials show the possibility of melt spinning TPS-based biopolymers into fibers even with higher content of TPS as well as neat TPS giving an insight and motivation for more research engagement. The melt-spun fibers were found to have a diameter in the range of 160.0–117.0 μm. However, additional experiments and investigations are required to improve the mechanical and other properties of the fibers.","PeriodicalId":11806,"journal":{"name":"e-Polymers","volume":null,"pages":null},"PeriodicalIF":3.7,"publicationDate":"2024-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141190450","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fourier transform infrared spectroscopy, X-ray photoelectron spectrometer, and atomic force microscopy results show that a RC film with a thickness of 25 nm is generated in the upper layer of TMSC film on the silicon wafer.

However, stress concentration around holes at the bolted joints leads to a decrease in bearing capacity. Composites often result in mechanical degradation subjected to a complex hydrothermal environment. Therefore, to study the tensile behavior of CFRP bolted joints subjected to hydrothermal aging, the tensile tests are conducted carefully. The influence of aging time and temperature on tensile strength is investigated based on the response history, strain contour, and failure morphology. The failure mechanism is revealed via digital image correlation technology. Finally, the experimental results demonstrate that the bearing capacity of the structure in hydrothermal aging decreases significantly. Compared with the unaged specimens, the peak force of the specimens aged for 6 weeks at 25°C and 65°C is reduced by 22.79% and 35.63%, respectively.
