Composites from biodegradable and biocompatible methylcellulose, poly(d,l‐lactide‐co‐glycolide) and poly(1,4‐butylene succinate) with enhanced properties

Abstract

Polymer materials based on fossil resources have brought great convenience to various industries. However, environmental pollution is becoming increasingly conspicuous due to their difficult degradation in nature. Therefore, biodegradable composites are highly desired. In the present work, a simple and feasible preparation approach was presented to fabricate biodegradable and biocompatible composite films including methylcellulose/poly(d,l‐lactide‐co‐glycolide) (MC/PLGA) and methylcellulose/poly(1,4‐butylene succinate) (MC/PBS). The effects of MC/PLGA and MC/PBS mass ratios on the morphology, crystalline state, mechanical properties and thermal stability of the composite films were systematically investigated. At the same time, the influence of thermal compression treatment on mechanical properties (tensile strength and elongation) and the cyclic utilization of the composite films were also estimated. The composite films displayed enough good mechanical properties, re‐usability and thermal stability.

“…Furthermore, the average pore diameters were tremendously reduced to 128.97 nm and 33.07 nm for PBS/TPS 1.5% BM and PBS/TPS 3% BM films, respectively. This implied that the nucleating effect of BM particles were more likely to show up when mixing with TPS and PBS components together [ 47 , 48 ]. The total pore volume remained insignificant change for PBS/TPS 1.5% BM and PBS/TPS 3% BM films as comparing to PBS/TPS film, possibly the TPS plasticizer still taking strong effect in enclosing the porosity of the film.…”

High performance polyvinyl alcohol/polylactic acid materials: Facile preparation and improved properties

“…[1][2][3][4][5][6] In this context, much attention has been payed to green and biodegradable products fabricated from nontoxic and biodegradable feedstocks such as polyvinyl alcohol (PVA), polylactic acid (PLA), poly(D,L-lactide-co-glycolide) (PLGA), poly(1,4-butylene succinate) (PBS), and so on. [7][8][9][10] In recent years, PVA has gained a significant interest because of its fascinating features including film forming, low friction factor, biocompatibility, biodegradability and permeability. [11][12][13] However, PVA has poor mechanical property and water-retention property, and it is difficult to be directly processed into desired product.…”

Cellulose blends from gel extrusion and compounding with polylactic acid

“…The combination of cellulose and polylactic acid (PLA) in green composites is a current topic in this context and could replace fossil materials in various applications. [1][2][3][4][5] Apart from using cellulose as a filler in thermoplastic matrices, only few attempts with regard to thermoplastic processing of cellulose as a matrix have been reported so far. In addition to dry processes using high shear and pressure, 6,7 the plastic deformation of cellulose has been studied mainly in wet processes.…”

“…The idea of using cellulose in thermoplastic processing has been an ever‐present topic in material research for a century. The combination of cellulose and polylactic acid (PLA) in green composites is a current topic in this context and could replace fossil materials in various applications 1–5 .
