11.3 Polycaprolactone (PCL)
PCL is biodegradable polyester with a low melting point of around 60 °C and a glass transition temperature of about −60 °C. PCL is prepared by ring-opening polymerization of ε-caprolactone using a catalyst such as stannous octanoate.
Similarly Where is PCL used? Biomedical applications
PCL has been widely used in long-term implants and controlled drug release applications. However, when it comes to tissue engineering, PCL suffers from some shortcomings such as slow degradation rate, poor mechanical properties, and low cell adhesion.
Is PCL hydrophobic? PCL was selected as a hydrophobic and polyvinyl alcohol (PVA) as a hydrophilic additive. These additives are already approved by FDA for application in human [15].
Additionally, Is PCL conductive?
PCL provides the structural support and mechanical cues while PPy-b-PCL provides conductive properties that can be exploited for neuronal regeneration.
Is PCL biocompatible?
Although derived from fossil sources, PCL is also biodegradable, biocompatible, and bioabsorbable. However, the high mechanical performance of PLA/PCL blends remains challenging to achieve due to the immiscibility of the polymers.
Is PCL amorphous? In the case of PCL, the glass transition is approximately −60 °C which means the amorphous regions of PCL are in a rubbery state at ambient conditions (25 °C) [19]. However, due to the semi-crystalline nature of PCL, the bulk material is a brittle and rigid solid below the melt and a liquid above the melt.
Is PCL soluble in water? At room temperature, PCL is highly soluble in chloroform, dichloromethane, carbon tetrachloride, benzene, toluene, cyclohexanone and 2-nitropropane; slightly soluble in acetone, 2-butanone, ethyl acetate, dimethylformamide and acetonitrile; and insoluble in alcohols, petroleum ether, diethyl ether and water.
Is PCL biobased? Biodegradable fossil-based polymers
Polymers such as polybutyrate adipate terephthalate (PBAT), polybutylene succinate (PBS), polycaprolactone (PCL) and polyvinyl alcohol (PVOH, PVA) are biodegradable polymers as their structure contains chemical groups that can be easily broken down by the action of microorganisms.
Does PCL absorb water?
PCL’s oxygen permeability is fairly comparable with that of polyethylene, that is, it cannot be used as a good oxygen barrier material. By contrast, with PE, however, it absorbs moisture and its water vapor permeability is especially high due to the polar ester groups in its molecular structure.
Is polycaprolactone a thermoplastic? Properties and Applications
Polycaprolactone (PCL) is a biodegradable, semi-crystalline thermoplastic polyester produced by cationic or anionic ring-opening polymerization of ε-caprolactone at elevated temperatures (≤ 200°C) and in the presence of a suitable catalyst such as dibutyltin dilaurate.
Is polycaprolactone hygroscopic?
The PCL Filler Possesses an Original Mechanism of Action
The immediate effect is related to the CMC gel by the filling capacity of the injected volume and the highly hygroscopic properties of CMC.
Is PCL hydrophilic or hydrophobic? 1.2.
Polycaprolactone (PCL), a hydrophobic polymer with semicrystalline structure, is made of caprolactone subunits linked together by the process of ring-opening polymerization.
Is PCL a thermoplastic?
Polycaprolactone (PCL) is a biodegradable, semi-crystalline thermoplastic polyester produced by cationic or anionic ring-opening polymerization of ε-caprolactone at elevated temperatures (≤ 200°C) and in the presence of a suitable catalyst such as dibutyltin dilaurate.
What is liquid PCL?
PCL-Liquid is a liquid oil-soluble emollient (mixture of alkyl branched fatty acid esters) providing outstanding skin suppleness that makes the skin soft and smooth. PCL-Liquid has been developed to mimic water-resistance and lipid auto-spreading of preen gland oil.
Is polycaprolactone Food Safe? PCL is an Food and Drug Administration (FDA) approved material that is used in the human body as (for example) a drug delivery device, suture (sold under the brand name Monocryl or generically), adhesion barrier and is being investigated as a scaffold for tissue repair via tissue engineering, GBR Membrane.
Is PVOH biobased? Hydroplast products are based on a polyvinyl alcohol (PVOH). This is a hydrophilic (water liking) and water-soluble polymer which is well documented as being inherently biodegradable.
Is PBAT bio based?
PBAT combines some of the beneficial attributes of synthetic and biobased polymers. It is derived from common petrochemicals—purified terephthalic acid (PTA), butanediol, and adipic acid—and yet it is biodegradable.
Is polycaprolactone a thermoplastic? Polycaprolactone (PCL) is a biodegradable, semi-crystalline thermoplastic polyester produced by cationic or anionic ring-opening polymerization of ε-caprolactone at elevated temperatures (≤ 200°C) and in the presence of a suitable catalyst such as dibutyltin dilaurate.
Does PCL undergo hydrolysis?
PCL is a long-term stable polymer when subjected to hydrolytic degradation conditions, and therefore requires 2–4 years for its complete degradation, depending on the starting molecular weight of the PCL [14].
Why is PCL used in tissue engineering? One of such polymers is poly(ε-caprolactone) (PCL), which is a polyester that has been widely used in tissue engineering field for its availability, relatively inexpensive price and suitability for modification.
