[ACS Sustainable Chemistry & Engineering] Flexible and Degradable Paper-Based Strain Sensor with Low Cost
It is a challenge to fabricate low-cost and flexible electronic devices with degradable materials. In this work, a flexible and degradable strain sensor was fabricated on a paper substrate by dip-coating in an aqueous suspension of carbon black (CB) and carboxymethyl cellulose (CMC). The composition of CB and CMC in the suspension was first studied for producing a uniform conducting layer o...

[Macromolecular Materials & Engineering] Mechanically Robust, Tough, and Self-Recoverable Hydrogels with Molecularly Engineered Fully Flexible Crosslinking Structure
How to reasonably fabricate polymer network for high performance hydrogels is a critical issue but remains a challenge. This work reports an approach to high performance hydrogels by molecularly engineering fully ?exible crosslinking (ffC) network. A model network cross-linked by fully ?exible crosslinking points of triblock copolymer micelles and ionic interactions is fabricated. Due to the...

[Adv. Mater.] One-Step Assembly of a Biomimetic Biopolymer Coating for Particle Surface Engineering
Advances in material design and applications are highly dependent on the development of particle surface engineering strategies. However, few universal methods can functionalize particles of different compositions, sizes, shapes, and structures. We describe the amyloid-like protein assembly-mediated surface modification and functionalization of particles and living colloids with different compos...

A Kind of Cotton-like Micro- and Nano- Poly (lactic acid) Nonwoven Fiber Fabricated by Centrifugal Melt-spinning for Tissue Engineering.
Biodegradable materials in the form of nonwoven fibers have attracted increasing attention for tissue engineering applications because they offer large surface areas and interconnected networks. In this study, cotton-like nonwoven poly(lactic acid) (PLA) fibers were successfully fabricated by centrifugal melt-spinning. The effects of centrifugal speed and secondary melt-spinning processing on t...

【[Frontiers of Chemical Science and Engineering]】Laser Ablation of Block Copolymers with Hydrogen-Bonded Azobenzene Derivatives
We investigated laser interference ablation
of block copolymer supramolecular assemblies. Supramolecular assemblies
(PS-b-P4VP(AzoR)) are fabricated by hydrogen-bonding azobenzene derivatives
(AzoR) to poly(4-vinyl pyridine) blocks of polystyrene-block-poly(4-vinyl
pyridine) (PS-b-P4VP). PS-b-P4VP(AzoR) forms phase separated nanostructures
with a period of ~75-105 nm. A second len...

【[ACS Sustainable Chemistry & Engineering]】Biodegradable PLA Nonwoven Fabric with Controllable Wettability for Efficient Water Purification and Photocatalysis Degradation
Although many bioinspired superwetting materials with excellent capability for oil/water separation have been constructed, functional surfaces combining effective separation property, biodegradability, and easy-controllability are still highly desired. In this work, a facile strategy to realize the controllable wettability on the polylactic acid (PLA) nonwoven fabric has been developed; the result...

50. [Chemical Engineering Journal] Tough and pH-sensitive hydroxypropyl guar gum/polyacrylamide hybrid double-network hydrogel
Using a facile two-step method, the researchers synthesized a pH-responsive double-network (DN) hydrogel with high strength and toughness, consisting of a B(OH)4? linked hydroxypropyl guar gum (HPG) network and a covalently cross-linked polyacrylamide (PAAm) network. The mechanical strength of HPG/PAAm DN gel was investigated as a function of synthesis conditions, HPG content, sodium borate conc...

ACS SUSTAINABLE CHEMISTRY & ENGINEERING------Designing Multi-functional Coatings for Cost-effectively Sustainable Water Remediation
Multi-functional coatings derived from bio-inspired dopamine (DA) engage
lots of attention for water environmental remediation recently. Nevertheless,
high cost of DA monomers seriously hampers their broad applications. Herein, an
elegant multi-functional coating which could be deployed as selective adsorbents
or loose nanofiltration membranes for removing of dyes and antibiotics fro...

【Chemical Engineering Journal】Preparation of lipase/Zn3(PO4)2 hybrid nanoflower and its catalytic performance as an immobilized enzyme
A facile and rapid method is reported in this paper to prepare a novel immobilized enzyme named lipase/Zn3(PO4)2 hybrid nanoflower. The growth mechanism of the nanoflower has been studied in detail and can be described as the following four steps: crystallization and coordination, in-situ precipitation, self-assembly, size growth. Addition amount of lipase, reaction temperature and stirring...

【Chemical Engineering Journal】 One-step thiol-isocyanate dispersion polymerization: preparation of uniform, cross-linked and functional particles
Uniform and highly cross-linked particles with functional groups are very useful but difficult to be achieved in traditional dispersion polymerization. Herein, we develop a one-step dispersion polymerization based on thiol-isocyanate reaction to prepare such particles. This polymerization proceeds energy-efficiently at ambient temperature without additional catalyst/initiator or UV treatmen...
