“…Comparing w and v 0.87 , the equation implies that both were influenced mainly by the wood content A and the interaction of AB in a negative manner. Besides, they also shared the presence and tendency of −AE and –AD, both in minor manifestations. It is known that the water absorption characteristics of TPU are comparably low, which explains the low influence of factor B in the above equations.…”

“…The incorporation of wood into PVC has drawbacks like the deterioration of stability against UV radiation and a negative public perception (chlorine content and plasticizer discussion). With respect to TPU, there are very few studies (nano‐composites exempted) about lignocellulosic composites . Publications about wood‐based TPU composites are confined to the paper by Lemos and de Martins that deals with a PLA‐based blend consisting of 30% TPU.…”

This research reports the influence of the mechanical properties of thermoplastic polyurethane (TPU) as a function of wood filler percentage. Wood flour was mixed with two different chemically based TPUs. Also, moisture content during compounding process as well as the origin of moisture (wood or TPU) were studied. All experimental designs and statistical analysis were done with the software Design Expert Version 10. Composite preparation took place in a multi‐stage process. The results showed that 70% wood filler can be incorporated in the composite manufacture. The properties of the composite were mainly influenced by the proportion of wood and TPU. Wood flour increased the density, hardness, water absorption, and tensile modulus with a decrease in impact resistance and abrasion resistance of the composite. Tensile strength exhibited a decrease up to ∼35% wood content, but an increase with further addition of wood. Moisture content had only a minor influence on the mechanical and water absorption properties despite the noted severe moisture sensitivity of TPU, which usually leads to decline in mechanical properties. © 2018 Wiley Periodicals, Inc.

PU formulation can be tuned to deliver desirable properties in specific applications 21 . Furthermore, composites may also be used as alternative to improve mechanical and thermal properties of PU [21][22][23] .…”

Polyurethane/poly (Ionic Liquids) Cellulosic Composites and their Evaluation for Separation of CO2 from Natural Gas

The development of both versatile and inexpensive sorbents for CO 2 /CH 4 separation has become one of the greatest challenges to the environment and natural gas processing. This study reports the preparation and characterization of polyurethane (PU)/ cellulose based poly(ionic liquid)(CPIL) composites for CO 2 /CH 4 separation. PU matrix was reinforced with CPIL in the range of 10-30 wt%. Several characterization techniques (TGA, DSC, DMTA and FESEM) were used to study the physical properties of composites when the PU matrix is reinforced with cellulose based poly (ionic liquids) (CPIL) up to 30%. CO 2 sorption, reusability and CO 2 /CH 4 selectivity were assessed by pressure-decay technique. Results showed that CPIL addition in PU matrix promoted the increase in both thermal stability and mechanical properties when compared to PU. The best result for CO 2 sorption (35.0 mgCO 2 /g) was obtained for PU/CPIL-TBP 10% which presented a higher sorption value when compared to PU (24.1 mgCO 2 /g) and PU/CELLULOSE 10% (26.8 mgCO 2 /g). PU/ CPIL-TBP 20% demonstrated higher CO 2 /CH 4 selectivity. PU/CPIL composites appear as promissory materials for CO 2 capture. These compounds combine the benefits of ionic liquids (ILs) (high ionic conductivity, chemical and thermal stability) and cellulose (thermal stability) with PU properties (mechanical stability, processing and tunable macromolecular design).

Abstract. Pineapple leaf fibre (PALF) was hybridized with kenaf fibre in order to achieve superior physical and flammability performance. The mixing effects of kenaf fibre and pineapple leaf fibre in phenolic composites are evaluated at various fibre ratios and investigated various physical properties such as density, void content water absorption, thickness swelling and flammability. Pure kenaf fibre composite showed lowest void content, water absorption and thickness swelling while pineapple leaf fibre revealed the opposite trend. After adding pineapple leaf fibre in kenaf composites, it absorbed more moisture and developed more void contents. Density of PALF composite was lower and kenaf fibre composite was highest but PALF/kenaf hybrid composite increased density with higher PALF. The flammability of hybrid composites were analysed by using UL-94 test method. Vertical and horizontal UL-94 test conducted to analyse fire resistance of composites from different angles. Phenolic resin is itself a fire resistant polymer and the percentage of polymer in all samples are fixed though ratios of both fibres pineapple leaf fibre and kenaf were change to analyse fire resistant of fibres and compatibility with polymers. The 70 % pineapple leaf fibre and 30 % kenaf fibre hybrid composites were very affective to improve the flammability of PALF/KF hybrid composites. 1.Introduction As far as the environment is the concern, renewable resources of materials are the best alternative material of good economic potential and protection of nature, since, the renewable resources are characterized as biodegradable and recyclable, lignocellulosic fibres belong to this category [1]. Nowadays, natural fibres as reinforced material have been increased considerably due its low price compared to synthetic fibers [2]. Waste management of lignocellulosic and renewable materials and poor mechanical strength and thermal stability of polymers can be improved by developing natural fibres reinforced polymer composites [3][4][5]. Some plants fibres have potential to be applied in industries as raw materials such as pineapple, kenaf, coir, abaca, sisal, cotton, jute, bamboo, banana, Palmyra, talipot, hemp, and flex [6][7]. Pineapple leaf fibre (PALF) is one of the waste materials in agriculture sector, which is widely grown in Malaysia as well as Asia. After banana and citrus, pineapple (Ananas comosus) is one of the most essential tropical fruits in the world [8]. Natural fibres influenced mechanical strength due to chemical composition such as to cellulose, hemicellulose and lignin and its orientation and some other factors such as type of plant, environmental factors during growth as well as extraction methods used [9]. Usage of natural fibre can replace synthetic fibres to minimise health hazards, low density and high flexibility [10].Recently, polymer hybrid composites have become the attraction into production of mechanical stable and renewable products [11]. Polymer hybrid composites are formed by incorporating two and
