Fumed silica particles (SiO2) were directly added into poly (butylene succinate) (PBS) by melt mixing process. The effects of amount of fumed silica particles on mechanical properties of PBS/fumed silica composites, those are tensile strength, tensile modulus, impact strength as well as flexural strength, were investigated. It was found that the mechanical properties decreased with increasing fumed silica loading (0-3 wt%). In order to increase polymer-filler interaction, fumed silica was treated with 3-glycidyloxypropyl trimethoxysilane (GPMS), and its structure was analyzed by FT-IR spectrophotometry. The PBS/modified was found to possess better tensile strength, tensile modulus, impact strength and flexural strength that those of PBS/fumed silica composites.

Specific Material

Polylactide (PLA), poly(butylene succinate) (PBS) and blends thereof have been researched in the last two decades due to their commercial availability and the upcoming requirements for using bio-based chemical building blocks. Blends consisting of PLA and PBS offer specific material properties. However, their thermodynamically favored biphasic composition often restricts their applications. Many approaches have been taken to achieve better compatibility for tailored and improved material properties. This review focuses on the modification of PLA/PBS blends in the timeframe from 2007 to early 2019. Firstly, neat polymers of PLA and PBS are introduced in respect of their origin, their chemical structure, thermal and mechanical properties. Secondly, recent studies for improving blend properties are reviewed mainly under the focus of the toughness modification using methods including simple blending, plasticization, reactive compatibilization, and copolymerization. Thirdly, we follow up by reviewing the effect of PBS addition, stereocomplexation, nucleation, and processing parameters on the crystallization of PLA. Next, the biodegradation and disintegration of PLA/PBS blends are summarized regarding the European and International Standards, influencing factors, and degradation mechanisms. Furthermore, the recycling and application potential of the blends are outlined.

New Type

Poly (butylene succinate) (PBS) was mixed with Poly (lactic acid) (PLA) through Haake Reomix, a new type of biodegradable materials can be obtained. With the increasing addition of PBS and the raise of the solution basicity, the degradation rate of blends increase sharply. The GPC analysis can approve the reduction of molecular weight in the degradation process of PLA/PBS blends.

Thermal Stability Of

The biodegradable films of the blend of pregelatinized starch and poly(butylene succinate) were prepared by using mixture of water and glycerin as plasticizing agent. The mechanical properties, thermal performance of the films and molecular weight of PBS were investigated. Gel permeation chromatography (GPC) results indicate that the molecular weight of PBS has no obvious change in spite of the presence of water. Starch can be well plasticized and uniformly dispersed in PBS matrix without obvious particles and agglomeration observed. When starch content was 10 wt% of total resin, the mechanical properties of the blend film is similar to that of pure PBS. With the further increase in the starch content, the mechanical properties were reduced; the crystallization temperature of the blend increased and the crystallization time is shortened. The thermogravimetric analysis found that pregelatinized starch and PBS decomposed in their respective temperature, the thermal stability of materials decreased.
