“…In addition, photodegradation process of PVC leads to the formation of cross-linked chains which could be the reason for the honeycomb porous structure formation. Previous reports indicated that cross-linked materials are ideal for the production of honeycomb-like structures in which condensed water was stabilized [42, 43, 44, 45, 46, 47]. For example, deep irradiation (6 h at 25 °C) of crossed linked polystyrene thin film leads to the formation of a honeycomb-like structure [43].…”

“…The honeycomb film was fabricated using the phase separation method which involves the use of chloroform and methanol mixture (9:1 by volume) [43]. Also, a honeycomb film of poly(acrylic glycidyl ether) was produced upon irradiation of the polymeric material, with a UV light for a short time, in dichloromethane or chloroform as a solvent, using the breath figure technique [44].…”

The fabrication of tunable poly(vinyl chloride) porous films containing polyphosphate as an additive was successful. Irradiation of poly(vinyl chloride) films containing polyphosphate at a low concentration (0.5% by weight) with an ultraviolet light (λmax = 313 nm) for 300 h leads to the formation of a honeycomb like structure. The scanning electron microscopy images, at different magnification power, confirmed the production of the PVC honeycomb-like structure. The morphological images of the polymeric film showed a rough surface and a large number of regularly distributed hexagonal pores. The number of pores increased upon irradiation time and it was maximum after 300 h. The honeycomb structure formation could be due to the regular aggregation of polyphosphate among the polymeric chains, the increase in solution intrinsic viscosity and evaluation of hydrogen chloride gas through dehydrochlorination process.

“…This study selected the hydrogel prepared from 2‐(dimethylamino)ethyl methacrylate (DMAEMA)and crosslinker N , N ′‐methylene diacrylamide (MBA), and hydroxyethyl acrylate (HEA) through photopolymerization as an example. The monomer glycidyl methacrylate (GMA) that possesses two different functional groups, namely, double‐bond acrylate, which can be radically photopolymerized, and an epoxy group, which can be cationic photopolymerized, was photografted on the hydrogel surface through hydrogen abstraction photopolymerization. Cationic photopolymerization of epoxy on each building block of polyglycidyl methacrylate (PGMA) was then used to crosslink the PGMA polymer chain .…”

This study reports an effective method for controlling substance-release sites of hydrogel. Glycidyl methacrylate, which contains two functional groups, namely, double-bond acrylate and epoxide, is photografted on a hydrogel surface through hydrogen abstraction photopolymerization due to the existence of a hydrogen donor, such as an amine, in the hydrogel matrix. The remaining epoxide group crosslinks the polymer chain of polyglycidyl methacrylate. Substance release of hydrogel is changed due to the altered surface texture of hydrogel. Rate and site-controlled substance release are achieved by controlling the thickness and site of surface grafting and the extent of epoxide ring opening. This study may provide a novel method for achieving hydrogel function or modified performance of other biomaterials to meet biological activity requirements.

“…Crosslinking of the polymer matrix via UV irradiations has been widely applied due to its versatility under soft conditions. Indeed, this method, which does not require heating, can be used for a wide range of polymers including polystyrene (PS), [ 11–13 ] poly(meth)acrylates [ 14–18 ] or polybutadiene (PB).

“…Methacrylate based homopolymer was also used to fabricate cross‐linked HC film where linear homopolymer poly(glycidyl methacrylate) (PGMA) is considered as a template for chemical vapor deposition (CVD) of SiO 2 particles. [ 15 ] After the HC formation, the film was immersed into photo‐initiator solution and exposed under UV light during 2 min. They proved that a short polymer film exposure under UV irradiation improved thermal stability and solvent resistance through crosslinking of epoxy groups.…”

This review is in line with the principles of bio‐inspiration and biomimicry in order to envisage a softer and more environmentally friendly chemistry. Here, the source of inspiration is a microalga from the oceans with the ability to build an exoskeleton of silica under ambient conditions. Following this model, this review is interested in different ways of creating porous silica films with a hierarchical porosity similar to diatoms. For this purpose, polymeric/hybrid/inorganic films structured in honeycomb using the breath figure method are reported. This versatile and easy to implement method based on the principle of rapid evaporation of a solvent in a humid atmosphere is widely used in the formation of structured films with micron‐sized pores. In addition to this, the self‐assembly of copolymer at the nanoscale can be addressed to obtain a hierarchically structured film. Following this structuration step, the degradation of a sacrificial block is then described from the most energy‐intensive to soft process, allowing an added nanoporosity to the micron porosity of the BF method. Finally, hierarchical porous silica films are described using the sol–gel process, which is known as a soft chemistry process.
