“…51 A variety of commercial end uses are afforded by blending PP with a variety of fillers or other polymers in ratios that can accordingly tune the desired thermal, mechanical, or morphological properties of the final blend. 52 For example, the widespread availability of both PP and PS motivates the exploration of PP:PS blends to engineer materials with a range of uses. 53 Since the strong immiscibility of PP and PS hampers the mechanical performance of PP:PS, 54 low percentages (<5− 10 wt %) of compatibilizers such as maleic anhydride-grafted polypropylene (MA-g-PP) 55 or styrene-ethylene-butylenestyrene (SEBS) 56 are often incorporated into these blends to mitigate phase separation.…”

The development of high-throughput experimentation (HTE) methods to efficiently screen multiparameter spaces is key to accelerating the discovery of high-performance multicomponent materials (e.g., polymer blends, colloids, etc.) for sensors, separations, energy, coatings, and other thin-film applications relevant to society. Although the generation and characterization of gradient thin-film library samples is a common approach to enable materials HTE, the ability to study many systems is impeded by the need to overcome unfavorable solubilities and viscosities among other processing challenges under ambient conditions. In this protocol, a solution coating system capable of operating temperatures over 110 °C is designed and demonstrated for the deposition of composition gradient polymer libraries. The system is equipped with a custom, solvent-resistant passive mixer module suitable for high-temperature mixing of polymer solutions at ambient pressure. Residence time distribution modeling was employed to predict the coating conditions necessary to generate composition gradient films using a poly(3-hexylthiophene) and poly(styrene) model system. Poly(propylene) and poly(styrene) blends were selected as a first demonstration of high temperature gradient film coating: the blend represents a polymer system where gradient films are traditionally difficult to generate via existing coating approaches due to solubility constraints under ambient conditions. The methodology developed here is expected to widen the range of solution processed materials that can be explored via high-throughput laboratory sampling and provides an avenue for efficiently screening multiparameter materials spaces and/or populating the large data sets required to enable data-driven materials science.

“…In order to improve the mechanical properties of PLA and obtain strong PLA, inorganic nanoparticles can be introduced into the system to form a ternary composite toughened system. Montmorillonite, tricalcium phosphate and hydroxyapatite have been used [7]. It is proved that it can promote the mechanical properties of the material.…”

“…Esse resultado confirma a expectativa de aplicação desse aditivo, que por ser um copolímero de propileno-etileno rico em propileno e alto conteúdo amorfo, que quando misturado ao PPr não altera de forma significativa a transparência, resultado de grande interesse para a aplicação desse material. (CHUKOV et al, 2017;LU et al, 2017) A literatura técnica do AGt, fornecida pelo fabricante, reforça a sinergia entre os dois materiais e demonstra graficamente em seu estudo, que com a adição de até 10% desse material ao PPr não ocorre diferença na transparência do produto e obtêm-se peças com baixo índice de opacidade.…”
