A method for plasma ion processing is described, including flowing a gas into porous material; and exposing the gas to a pulsed electric field whilst the gas is in the pores. The pulsed electric field ionises the gas to generate a plasma. The method may additionally include exposing the porous material to a gas so as to generate functionality. The method may additionally include exposing the functionalised porous material to a functional species so as to covalently attach said functional species to the surfaces of the pores.

A composite resin molded product of the invention is a composite resin molded product, including: a main agent resin; and a plurality of natural fibers dispersed in the main agent resin. The plurality of natural fibers each contain a microorganism or an enzyme. When the composite resin molded product is 100% by mass, a content rate of the plurality of natural fibers each containing the microorganism or the enzyme in the composite resin molded product is 10% by mass or more and 99% by mass or less. At least one of the plurality of natural fibers is exposed on a surface of the composite resin molded product. At least a part of a surface of the at least one of the plurality of natural fibers is coated with a hydrolyzable coating resin.

An objective of the present invention is to provide a production method that enables PHA (e.g. PHA powder) to be produced with high productivity. The above is achieved by providing: a method for producing a polyhydroxyalkanoate, including the steps of (a) preparing an aqueous suspension that contains a polyhydroxyalkanoate and an alkylene oxide-based dispersing agent and has a pH of not more than 7 and (b) spray-drying the aqueous suspension prepared in the step (a); and the like.

Nanoscopic dispersion of trace enzymes and random heteropolymers in plastics provides to fully functional plastics with eco-friendly microplastic elimination and programmable degradation.

Provided are a liquid crystal polymer (LCP) film and a laminate comprising the same. The LCP film has a first surface and a second surface opposite each other, and a Kurtosis (Rku) of the first surface ranges from 3.0 to 60.0. With the Rku, the LCP film is able to improve the peel strength with a metal foil and ensure that a laminate comprising the same maintains the merit of low insertion loss.

The invention relates to the manufacturing of porous polymer membranes by (a) providing pellets comprising a polymer matrix and particles in the ratio 90:10 to 10:90, (b) converting said pellets into a non-porous film by a solvent-free process; (c) removing said particles from said film with an aqueous composition to thereby obtain said membrane. The invention further relates to pellets useful in such manufacturing process as well as porous polymer membranes obtainable or obtained by such manufacturing process as well as textile materials and articles containing such membranes; to the use of such pellets, membranes, and articles.

A process for chemically recycling polyethylene terephthalate (PET) which utilizes a microwave absorber to optimize glycolytic depolymerization of PET via microwave irradiation. The method of chemically degrading PET to its reactive intermediate, bis(2-hydroxyethyl) terephthalate (BHET), is carried out by: (a) combining PET with ethylene glycol and a catalytic system comprising a catalyst and a microwave absorber to produce a heterogeneous reaction mixture; and then (b) heating by microwave irradiating the reaction mixture to a temperature sufficient to produce a reaction product comprising BHET. The BHET monomer then can be purified and re-polymerized to form new, virgin PET.
