The morphology of PSU/Nylon 6, 6 blend nanocomposites with various amounts of clay has been examined using scanning electron microscope (SEM), transmission electron microscope (TEM), and wide-angle X-ray diffraction (WAXD). In the case of 80/20 (w/w) PSU/Nylon 6, 6 without clay, the Nylon 6, 6 is dispersed in the PSU matrix with an average particle size of about 6.81 micrometers (μm). After adding clay (2%, 4%, and 8%), the domain size of nylon 6, 6 decreases, although the decrease rate is much slower than initially observed. However, we discovered that when the organoclay level exceeds 2%, the matrix-domain structure transforms into a co-continuous morphology for the 60/40 (w/w) blends. The TEM studies clearly demonstrate that the organoclay preferentially positions itself in the nylon 6, 6 phase, exhibiting a high degree of exfoliation, while the PSU phase of the nanocomposites remains devoid of clay, irrespective of the amount present. This study indicates that the size of clay platelets dispersed in the PSU/Nylon 6, 6 blend plays an important role in determining the morphology and stability of these blends. Moreover, the co-continuous structures were stable against further annealing at high temperatures, thus inhibiting the coalescence of the dispersed phase in addition to reducing interfacial tension.","PeriodicalId":17446,"journal":{"name":"Journal of Thermoplastic Composite Materials","volume":"33 1","pages":""},"PeriodicalIF":3.3,"publicationDate":"2024-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141871714","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To keep eye on that, this review paper focused on the replacement fossil based polymer with introducing biopolymer Polylatic Acid (PLA) polymer matrix composite with the incorporation of different leaf fiber. The intention of the current review is to represent the detailed idea for the development of PLA polymer matrix composite with the incorporation of different leaf fiber and with the proper selection compatibilizer to enhance the mechanical, degradation and other properties. Among these, leaves, once relegated to the realms of waste, have risen as potent contributors to the realm of fiber composites. The spotlight of exploration falls on green composites reinforced with leaf fibers, showcasing mechanical properties and modulus that surpass other classes of polymer composites. This revelation not only reshapes our understanding of plant-based fibers but also propels them into the forefront of innovation across industries. The modified composite can be used as various packaging materials in different areas like in textile industry, medicine and drug packaging, food industry for food packaging etc. This overview will support the researchers to engage in the development of degradation capability with enhancing mechanical properties of bio-sourced materials as composite materials. In essence, this review not only describes the essence of leaf fiber based composites but also acts as a main role for a greener, more sustainable future. It deliberates the necessity of leaves, transforming them from waste into a usable product thereby producing more strength in composite materials.","PeriodicalId":17446,"journal":{"name":"Journal of Thermoplastic Composite Materials","volume":"16 1","pages":""},"PeriodicalIF":3.3,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141772456","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Trans-1,4-polyisoprene has crystallinity and toughness properties, whereas polystyrene has transparent and brittle nature. These matrices have revealed shape memory effects through the inclusion of carbon nanoparticles like graphene and carbon nanotube, as well as inorganic nanoparticles like titania, silica, and metal nanoparticles. The nanoparticle addition has been found to induce shape changes as well as microstructural and physical property alterations in the matrices. This state-of-the art review article reports on the stimuli responsiveness of important categories of trans-1,4-polyisoprene and polystyrene based nanocomposites. These nanomaterials revealed important thermal, electric, and radiation induced responses. High performance shape memory effects have been observed depending upon the nanoparticle type, contents, and interactions with the polymer network. With the carbon nanoparticles like carbon nanotube, graphene, or carbon black, trans-1,4-polyisoprene revealed high shape recovery responses of 95%–99%. The nanocomposites of copolymers or blends of trans-1,4-polyisoprene also depicted the shape recovery of up to 100%. The shape memory nanocomposites of polystyrene and its blends and copolymers with different types of nanoparticles exhibited effective thermo responsive and electro active shape memory behavior. Consequently, the effective shape memory effects have been attributed to the homogeneous nanoparticle dispersion as well as the network formation for an active polymer chain switching.","PeriodicalId":17446,"journal":{"name":"Journal of Thermoplastic Composite Materials","volume":"41 1","pages":""},"PeriodicalIF":3.3,"publicationDate":"2024-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141737686","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This means that huge amounts of the resources utilized in food production are wasted. Greenhouse gas emissions caused by food degradation that gets wasted results in serious environmental and human health impacts. Food losses could be caused by microbes, temperature, humidity, UV-lights, or other factors related to the current pandemics, that have serious jeopardy impacts on the food security and the environment. Thus, smart packaging-based 2D-nanomaterials (2DMs) including sensors and pH-responsive tags have developed for achieving the quality and prolong the shelf-life of foodstuffs. Because they are capable to detect, sense, record internal or external changes in the product’s area. They also can give a prompt message or color changing to the producer or consumer to decide about the shelf lives and expiration dates for consuming the foodstuffs without deteriorating food and packaging. This study reviews the recent advancements in 2DMs regarding preparation, characterization, and applications including active/intelligent food packaging industries. Facile and green functionalization of 2DMs-based graphene oxide (GO) by folic acid or natural dyes enabling them be used in several sensor/artificial intelligence disciplines are discussed.

Filling these gaps and voids can be challenging during the consolidation due to the high viscosity of thermoplastic composites, especially in the case of vacuum-bag-only (VBO) consolidation, where the applied pressure is limited. Therefore, the current work investigates whether one bar pressure is sufficient to fill the gaps and voids during VBO consolidation. For this purpose, two experiments are performed. First, a hot plate setup is built and used to capture the real-time gap-filling behavior during the VBO consolidation. Second, VBO consolidation of tailored preforms is performed to study the filling of ply-drop induced void pockets. Here, the tailored preform consists of plies of different orientations dropped at different locations to verify if one bar pressure available during the VBO process is sufficient to fill the void pockets. The results from both experiments answered the main question that one bar pressure is sufficient for filling the gaps and void pockets for the given material systems, and further, it was confirmed that the transverse squeeze flow was dominant in filling gaps. However, in the case of fillings of ply-drop induced void pockets, the orientation of the dropped ply and covering plies majorly dictated the filling behavior.","PeriodicalId":17446,"journal":{"name":"Journal of Thermoplastic Composite Materials","volume":"68 1","pages":""},"PeriodicalIF":3.3,"publicationDate":"2024-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141737895","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The optimal blend, which includes equal amounts of sepiolite and graphene nanoplatelets (phr, 1 part per hundred resin each), exhibited a tensile strength of 54.5 MPa, representing an increase in tensile strength by 46.5% and an increase in percent strain by 59% as the GNP content increased from 0.2 to 1 phr, replacing sepiolite.

The impact strength also showed a notable 83% rise from HNC-G0.0 (252.97 J/m) to 463.18 J/m (HNC-G1.0). Despite these mechanical enhancements, Thermo Gravimetric Analysis (TGA) demonstrated the thermal stability of the nanocomposites. At the same time, Differential Scanning Calorimetry (DSC) confirmed that the melting temperature remained stable, ensuring consistent processing conditions.

A mechanical bench was specifically designed to study the interlaminar shear behavior of polymer-based laminates during the thermal aggression (imposed by a cone calorimeter). In C/PPS laminates, with respect to the reference values (as received state), the flexural modulus and the apparent ILSS (under 50 kW/m2) decreases by about 80%.
