“…Absorption ability in the oil system was studied by weighing the samples before (W i ) and after (W t ) immersing them in oil (Soybean, Engine) as percent weight gain (Q%) per the following equation. The test was repeated several times until the absorption process reached equilibrium [ 46 , 47 ]. :

With increasing industrial development, frequent oil spillages in water; therefore, it is imperative and challenging to develop absorbents materials that are eco-efficiency, cost-effective, and pollution prevention. In this study, sorbents obtained from Lignin incorporated with Polypropylene in different levels loading 0, 10, 20 % wt using thermally induced phase separation Technique (TIPS). The Polypropylene/Lignin blend monoliths were fabricated and compared in terms of morphological, thermal, and wetting characterizations. The successfully blending of different lignin concentrations with preserved the chemical structure of the polymer was confirmed by FTIR analysis. Thermogravimetric tests displayed that the existence of Lignin has changed the onset temperature (Tonset) of the blending sorbents, decreasing as the loading of Lignin is increased. The contact angle measurement showed a decrease in the hydrophobicity of sorbents with increasing lignin loading, Polypropylene/Lignin blend monoliths showed better absorption toward oils (soybean – engine) as compared to Polypropylene itself. PP10L showed an improvement in the oil sorption capacity around 2 times compared to the Polypropylene. These excellent features make Polypropylene/Lignin blend monoliths more competitive promising candidates than commercial absorbent.

“…The absorption ability was studied by weighing the samples before (W i ) and after (W t ) immersing them in oils (soybean, engine) as percent weight gain (Q) [38,39]. Samples were lifted and placed with free oil dripping out for 24 h, weight was measured ( W d ), then the retention was calculated (R) [40], and the weight gain and retention were calculated according to Eqs.…”

Polypropylene is widely used in oil spillage cleanup due to excellent characteristics. However, polypropylene is not renewable and biodegradable, which is unacceptable to introduce new pollutants while solving environmental disasters. Therefore, there is a high demand to explore a low-cost, environmentally friendly, and renewable technique for the fabrication of porous materials. In this work, lignin was chosen as the second blend in the polymer matrix. Polypropylene and renewable lignin sponges were successfully prepared using simple, inexpensive, controllable, scalable, and an environment-friendly method named thermally induced phase separation (TIPS). The surface morphology of obtained sponges was investigated using FTIR and SEM. FTIR analysis indicated that PP and lignin were physically blended. SEM analysis observed an interconnected porous network that acts as a capture site of oil, and lignin merged into PP. The contact angle of PP, PP5L, PP10L, PP15L, and PP20L was found to be 127.4°, 118.71°, 113.89°, 109.45°, and 107°, respectively. Furthermore, polypropylene/lignin sponges have good adsorption ability toward oils compared to polypropylene itself. The research detected that the highest oil sorption tests exhibited by PP10L sponge, which could absorb 983% of soybean oil, 788% of engine oil, and 550% of lubricating oil in the oil system, with high oil retention more than 90% after 24-h dripping. Besides, the results revealed that temperature has a significant effect on oil absorption. All of these features make polypropylene/lignin blend sponges promising sorbents for the oil spills cleanup, not only for oil recovery but also helps in cleaning the environment.

“…Recently, PP micro-nanofibrous fabrics have been proposed as a fashion, because the softness and comfort of the fabrics are mainly affected by the fiber properties and fabric structure. 6,7 Additionally, some nonwoven processes, including melt electrospinning and melt-blowing, have been used to prepare PP micro-nanofibrous fabrics. Lyons et al 8 reported PP micro-nanofibrous fabrics with fiber diameters that ranged from 0.79 to 30 μm created using a melt electrospinning setup with various structural features, for example, multi-jet, 9 needle-less, 10 high-speed hot-air blowing (Zetta spinning), 11 and centrifugal electrospinning.…”

The softness of polypropylene (PP) fabrics, which is related to fiber properties and fabric structure, is a pivotal perception for their application in skin contacts. However, tailoring the softness of PP fabrics remains challenging. The effects of mixing different percentages of polyethylene (PE) and PP during the melt-blowing process on the polymer properties and morphology characteristics, including the softness, preparation, and characterization of the micro-nanofibrous fabrics were determined. Rheological tests and differential scanning calorimetry results showed that the addition of PE helped destroy the crystalline integrity of PP. Moreover, scanning electron microscopy images depicted a fluffy structure consisting of micro-nanofibers with average diameters ranging from 1.3 to 3.2 μm. Furthermore, the softness scores ranged from 70.39 to 83.11 by changing the die temperature and PE mass ratio by applying a response surface model. Consequently, this micro-nanofibrous fabric may become a good material for skin contacts, such as baby diapers, feminine sanitary, and other personal hygiene uses.
