A novel biodegradable polymer blend was developed for potential biomedical applications. A 50:50 poly(lactide-co-glycolide) (PLAGA) was blended in a 50:50 ratio with the followiing polyphosphazenes (PPHOS): poly[(25% ethyl glycinato)(75% p-methylphenoxy)phosphazene[, poly[(50% ethyl glycinato)(50% p-methylphenoxy)phosphazene], and poly[(75% ethyl glycinato)(25% p-methylphenoxy)phosphazene] to obtain Blends A, B, and C, respectively, using a mutual solvent technique. The miscibility of these blends was determined by measuring their glass transition temperature (Tg) using differential scanning calorimetry. After fabrication using a casting technique, the degradation of the matrices was examined. Differential scanning calorimetry showed one glass transition temperature for each blend which was between the Tg's of their respective parent polymers indicating miscibility of the blends. Surface analysis by scanning electron microscopy showed the matrices to have smooth uniform surfaces. Degradation studies showed near-zero order degradation kinetics for the blends with Blends A and B losing 10% of their mass after two weeks and Blend C degrading more rapidly (30% mass loss during the same period). These findings suggest that these novel biodegradable PLAGA/PPHOS blends may be useful for biomedical purposes.
This research output has an Altmetric Attention Score of 9. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 15 March 2012.
All research outputs
#5,056,682
of 34,054,827 outputs
Outputs from Biomaterials
#2,347
of 13,209 outputs
Outputs of similar age
#8,275
of 131,683 outputs
Outputs of similar age from Biomaterials
#5
of 36 outputs
Altmetric has tracked 34,054,827 research outputs across all sources so far. Compared to these this one has done well and is in the 83rd percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 13,209 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 7.8. This one has gotten more attention than average, scoring higher than 72% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 131,683 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 89% of its contemporaries.
We're also able to compare this research output to 36 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 80% of its contemporaries.
