Description
Technical field
The present invention relates to polymeric material fields, more particularly to one kind to have excellent oxygen absorption function PEN material and its preparation
Methods and applications.
Background technique
(ethylene naphthalate) (PEN) is commercialized polyester new varieties the 1990s.With poly terephthalic acid
Equally, PEN can be processed into film, fiber, hollow container and sheet material to class plastics (PET).Due to its excellent combination property, have wide
Wealthy potential market, thus cause the concern of Polyester industry.
The structure of PEN is similar to PET, the difference is that PEN is by the bigger naphthalene nucleus of rigidity instead of benzene in strand
Ring, it is the polymer as obtained by 2,6-naphthalenedicarboxylic acid dimethyl ester and ethylene glycol polycondensation.In the molecular structure of PEN, due to naphthalene
The structure of ring be easier be in it is planar, make PEN that there is better barrier properties for gases, for example PEN is PET to the barrier property of aqueous vapor
3-4 times, the shelf-life of product is greatly improved as packaging material.The introducing of naphthalene nucleus improves the fragrance of macromolecular in molecule
Degree, so that PEN reveals more excellent heat resistance than pet sheet.The fusing point of PEN is 265 DEG C, and glass transition temperature is at 120 DEG C
More than, 50 DEG C or so are higher by than PET;Long-term use temperature is up to 160 DEG C, PEN placed in 180 DEG C of dry air 10h with
Afterwards, elongation is still able to maintain 50%.And PET will become not being available under similarity condition.In addition, the copolymer of PET/PEN
Also there is apparent effect to the hot property for improving PET.Young modulus and tensile modulus of elasticity the ratio PET of PEN is higher by 50%,
At 170 DEG C, the mechanical performance of PEN is significantly larger than PET.Since the twin nuclei of naphthalene has very strong ultraviolet absorption ability, it
The ultraviolet light that wavelength is less than 380nm can be obstructed, photostability is about 5 times of PET, the radioresistens in vacuum and O2
Ability is respectively up to 10 times of PET and 5 times.Although the ester group in PEN strand meets water decomposition, its decomposition rate is only
The 1/4 of PET, the ability of acid and alkali resistance is also superior to PET.
Since the air-tightness of PEN is good, molecular mass is relatively large, therefore at a temperature of actual use, the tendency of oligomer is precipitated
Small, the low aldehyde decomposed to give off in the case where processing temperature is higher than PET is also less than PET.Although PEN is crystallization as PET
Property material, but PEN transparent can be formed in non-crystalline state.Innocenzo of DuPont Display et al. is in SID
2003 have delivered the PEN plastic supporting base correlative study PEN that can be applicable to flexible display in the coating for adding people to have smooth effect
After layer, maximum prominent defect is not above 0.02 μm, and substrate is greater than 80% in the light transmittance of visible region, thermal stability ratio
PET is good, is highly suitable as the substrate of flexible display.But since luminous organic material is very sensitive to steam and oxygen,
To meet requirement of the Flexible Displays to substrate, 10-6g/m2/day need to be reached to the obstructing capacity of aqueous vapor, and blocking oxygen
Ability need to reach 10-3cc/m2/day.PEN individually hinder oxygen characteristic can not fully meet requirements at the higher level barrier film it is for example soft
The application of property Electronic Packaging.
By active oxygen scavenger, can be incorporated into the skeleton for constituting the basic polymer material of package wall, thus shape
At the polymer for removing oxygen.The oxygen-scavenging polymer can be used for mixing with other polymers, or as the removing in laminated vessel
Oxygen layer.The oxygen in environment can be reduced or be exhausted, at least can be used to overcome some limitations of passive barrier system.
For example, US 8,921,487 discloses the method for oxygen molecule in the clear thermoplastic article in addition to polyamides of one kind,
A kind of structural polymer with the carbon-to-carbon unsaturated bond easily to react with oxygen molecule.The terpolymer is gathered by big ring
What (alkyl-dimethyl acid diesters) oligomer, unsaturated functional polymer and epoxide function cinnamic acrylic ester oligomer formed
Polymerizate.
US 9,617,375 discloses a kind of method for removing oxygen in the thermoplastic article other than polyester, including will
Oxygen molecule reducing agent is mixed into thermoplastic compound, and reducing agent is that there is one kind carbon-to-carbon unsaturated bond easily to react with oxygen molecule
Copolymer, the polymerizate including cycloaliphatic monomer and unsaturated functional polymer.The Oxygen scavenging performance of copolymer by
It is produced after copolymer polymerization as the presence of the carbon-to-carbon unsaturated bond of the non-reacted parts of unsaturated functional polymer's reduction components
It is raw.
Since this method is that unsaturated copolymer is added directly into matrix resin to mix, although carbon-to-carbon is unsaturated double
Bond energy reacts with oxygen, it is also possible to there are two kinds of resin compatibles, it is understood that there may be the mutually separation of resin, thus shadow
Ring the absorption barrier property of oxygen.
