Abstract
Controlling the course of the degradation of aliphatic polyesters is a key question when designing new degradable materials.
Highlights
A paradigm shift has occurred in the field of biodegradable polymers, in which the current trend is to design and synthesize polymers with unique chemistry and diverse structures that can tailor their properties towards specific applications while taking into consideration sustainability in their creation.[1,2,3] This environmentally responsible approach contemplates the use of materials from renewable feedstock and further engineering of degradation pathways under a reasonable timeframe
Predefined hydrolysis paths were achieved by controlling the heterogeneity of the amorphous phase in aliphatic block copolyesters
Copolymers presenting strong secondary interactions between its blocks were characterized by the presence of a more homogeneous amorphous phase, represented by PCL and PεDL in the composition
Summary
A paradigm shift has occurred in the field of biodegradable polymers, in which the current trend is to design and synthesize polymers with unique chemistry and diverse structures that can tailor their properties towards specific applications while taking into consideration sustainability in their creation.[1,2,3] This environmentally responsible approach contemplates the use of materials from renewable feedstock and further engineering of degradation pathways under a reasonable timeframe. Taking “full advantage” of these materials is hindered by some unsolved problems. Among these challenges is the lack of deep insight and true under-. Degradation of these polymers can be both a desirable and undesirable process depending on the time of occurrence. By controlling this phenomenon, it is possible to predict the lifetime of materials and tailor them to specific needs. The degradation occurs through cleavage of hydrolytically sensitive bonds in the polymer backbone, leading to disintegration of the material.
