Nanohydroxyapatite/poly(lactic-co-glycolic) acid
(n-HA/PLGA) composite was reinforced by bamboo fiber (BF), and the
effects of BF of different lengths (≤1, 4–5, and 9–10
mm) on the mechanical properties, crystallization behavior, and in
vitro degradation of the composite were investigated by an electromechanical
universal tester, scanning electron microscopy, differential scanning
calorimetry, polarized optical microscopy, and soaking in simulated
body fluid (SBF) at 37 °C for 2, 4, 8, and 12 weeks, compared
with the n-HA/PLGA composite. The results showed that BF (4–5
mm) had excellent comprehensive reinforce performance based on the
best interface bonding and the best promotion crystallization effect.
However, the in vitro degradation experiment revealed that the BF
(≤1 mm) had the slightest tensile strength reduction percent,
because the shortest size has difficulty escaping from the n-HA/PLGA
matrix. The present work would provide important guidance significant
for selecting the appropriate bamboo fiber length to prepare an ideal
PLGA-based composite used for bone materials.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
