“…The addition of α‐1,3‐glucan improved the properties of TPU, most notably the modulus and strength, when 80% by weight of α‐1,3‐glucan was incorporated. The modulus and strength obtained by the addition of 80% α‐1,3‐glucan was within the same order of magnitude as polystyrene packing material 26,27 and paper pulp 28 . This improvement of modulus and strength, which is not obtainable from TPU without the addition of the α‐1,3‐glucan filler material, demonstrates the feasibility of using this composite as films and packaging materials.…”

This study explores the use of α‐1,3‐glucan, which can be produced through an enzymatic polymerization process, as additive for thermoplastic polyurethane composite systems. Most importantly, highly filled thermoplastic polyurethane composites can be achieved with up to 80% by weight polysaccharide content. Analysis of mechanical properties demonstrates that strength and modulus can be significantly improved, while the plasticizer content allows for adjustments of compound flexibility. The addition of 60% α‐1,3‐glucan increased the flexural modulus of the thermoplastic polyurethane by 497% while adding 80% α‐1,3‐glucan increased the flexural modulus by 3193%. Citrate esters can be incorporated as plasticizer to improve processibility and flexibility of the compounds. An increase in impact strength of 55% was achieved when 10% of tributyl citrate was added to the 80% α‐1,3‐glucan composite. Based on the compatibility and property enhancements, the use of these engineered polysaccharides may provide additional options for producing sustainable composite materials with high renewable content and unique properties.

“…4, the percentage elongation of OA 20 SBE is calculated as 3.21 %. The percentage elongation of OA 20 SBE was considered to be high by comparison with the research done by [6]. according to [6], the highest percentage elongation obtained by testing on various types of biopolymers was only 2.6 %.…”

In this paper, the mechanical properties of carboxymethyl cellulose-oleic acid (CMC-OA) solid bio-polymer electrolyte (SBE) were examined. The host, CMC was doped with different weight percentage (wt. %) of OA in the CMC-OA solution. The SBEs were tested by using the Universal Material Testing Machine where the readings of tensile strength and Young’s modulus can be obtained from the stress-strain curve produced by the software during the tension test. The sample of CMC doped with 20% wt. of OA was found to obtain the highest value of tensile strength and Young’s modulus which is 0.2069 MPa and 4.615 MPa respectively.
