“…However, they can also be, as in liquid medium according to ASTM standard, degraded by a fractionated way (Figure 23). This behavior is similar to that observed by Mayer et al [Mayer et al, 1995] who studied the biodegradation in soil and compost of a material combining cellulose acetate from degree of substitution 2.5 and propylene glycol. Indeed, the authors had to extend the incubation to detect weight loss on cellulose acetate in the blend.…”

“…Additionally, blending two or more chemically and physically dissimilar natural polymers has shown potential to overcome these difficulties. Over the years several materials have been blended with starch to improve its processability, including, but not restricted to, several synthetic polymers, such as polyethylene [156], polycaprolactone [157], polyethylene-co-vinyl alcohol [158], poly(hydroxybutyrate-co-valerate) [159], among others [160,161], or even other natural origin materials such as other polysaccharides [162] and proteins [163]. Starch has also been extensively modified by chemical methods such as oxidation [164] and grafting of acryl reactive groups [165].…”

The present paper intends to overview a wide range of natural-origin polymers with special focus on proteins and polysaccharides (the systems more inspired on the extracellular matrix) that are being used in research, or might be potentially useful as carriers systems for active biomolecules or as cell carriers with application in the tissue engineering field targeting several biological tissues. The combination of both applications into a single material has proven to be very challenging though. The paper presents also some examples of commercially available natural-origin polymers with applications in research or in clinical use in several applications. As it is recognized, this class of polymers is being widely used due to their similarities with the extracellular matrix, high chemical versatility, typically good biological performance and inherent cellular interaction and, also very significant, the cell or enzyme-controlled degradability. These biocharacteristics classify the natural-origin polymers as one of the most attractive options to be used in the tissue engineering field and drug delivery applications.

“…The majority of these products is biocompatible and biodegradable and has shown potential applications as bioresorbable sutures, drug delivery, implants, tissue scaffolding, and amongst others. 5,[7][8][9][10] In fact, a variety of cellulose esters exists; however, cellulose acetate and cellulose acetate butyrate (CAB) are the main commercial forms used in the pharmaceutical and medical fields. The versatility and relatively straightforward processing method for CAB make it likely a contender for modern medical devices.…”

Cellulose acetate butyrate/poly(caprolactonetriol) blends: Miscibility, mechanical properties, and in vivo inflammatory response

et al. 2014

This study reports the results of the characterization of cellulose acetate butyrate and polycaprolactone-triol blends in terms of miscibility, swelling capacity, mechanical properties, and inflammatory response in vivo. The cellulose acetate butyrate film was opaque and rigid, with glass transition (T g ) at 134℃ and melting temperature of 156℃. The cellulose acetate butyrate/polycaprolactone-triol films were transparent up to a polycaprolactone-triol content of 60%. T g of the cellulose acetate butyrate films decreased monotonically as polycaprolactone-triol was added to the blend, thus indicating miscibility. FTIR spectroscopy revealed a decrease in intramolecular hydrogen bonding in polycaprolactone-triol, whereas no hydrogen bonding was observed between cellulose acetate butyrate and -OH from polycaprolactone-triol. The increase in polycaprolactone-triol content in the blend decreased the water uptake. An increase in polycaprolactone-triol content decreased the modulus of elasticity and increased the elongation at break. A cellulose acetate butyrate/polycaprolactone-triol 70/30 blend implanted in rats showed only an acute inflammatory response 7 days after surgery. No change in inflammation mediators was observed.
