Investigation of Mechanical and Structural Properties of Blend Lignin-PMMA

Abstract

Thisin vitrostudy investigated the mechanical and structural characteristics of lignin-added PMMA resin composites at concentrations of 1, 3, and 5% by weight. Four sample groups were formed. For the transverse strength test, the specimens were prepared in accordance with ANSI/ADA specification number 12, and for the impact test ASTM D-256 standards were used. With the intent to evaluate the properties of transverse strength, the three-point bending (n=10) test instrument (Lloyd NK5, Lloyd Instruments Ltd., Fareham, Hampshire, UK) was used at 5 mm/min. A Dynatup 9250 HV (Instron, UK) device was employed for the impact strength measurements (n=10). All resin samples were tested by using a thermomechanical analyzer (Shimadzu TMA 50, Shimadzu, Japan). Mechanical tests revealed that, although the control group was found to have the value of highest transverse strength, the highest impact strength was observed in the PMMA-L-1 group. Upon examining the thermomechanical analysis data, it could be seen that theEvalue of the control sample was higher than that of all the other samples. Adding lignin powder into PMMA performs plasticizer effect on resin matrix.

Comparison of the thermal, dynamic mechanical and morphological properties of PLA-Lignin & PLA-Tannin particulate green composites

“…[26][27][28] However, this behavior was shown to vary for certain polymeric systems as shown in a study on PMMA based Lignin blends where, Lignin was shown to reduce transverse modulus & strength but improve impact resistance. [29] The structural complexity of Lignin also provides prospect for chemical modification. It was found that alkylated Lignin blended with PP to increase compatibility, improved both the impact strength and damping effect even with upto 40wt% alkylated Lignin content.…”

Behavior of epoxy reinforced banana glass fiber hybrid composite with nanoclay interference

“…This may due to the lower content of lignin present in the natural fiber which enhances the impact strength of the composites. 39,40 Lignin content of banana fiber is lower than abaca fiber.…”

Compatibilization of polyvinyl chloride ‐ polymethyl methacrylate polymer blends with maleic anhydride‐styrene‐methyl methacrylate terpolymer

“…In studies where the mixing of different polymers can be achieved, it has been observed that the resulting blend usually has the superior properties of the components. [1][2][3] Polyvinyl chloride (PVC) is a common commercial polymer. Due to its halogen content, it shows superior properties in terms of nonflammability and low-cost features.…”

“…In another study, Imren D. et al made PVC and EVA miscible with a maleic anhydride‐based compatibilizer and improved its thermomechanical properties 1 . Materials similar to the chosen Maleic anhydride based agent as a compatibilizer were used in our previous studies and successful results were obtained on different polymer pairs 1–3,11 . The advantage of this study from previous studies is that the compatibilizer used was synthesized in our own laboratory and the mixtures were prepared by solution casting, which is a simple and inexpensive process.…”
